mikoBasic PRO for PIC32 Active Comments The idea of Active Comments is to make comments alive and give old fashioned comments new meaning and look. From now on, you can assign mouse event on your comments and ‘tell’ your comments what to do on each one. For example, on left mouse click, open some web address in your browser, on mouse over show some picture and on mouse double click open some file.
mikroBasic PRO for PIC32 You can notice that when you start typing a name, properties pane is automatically displayed so you can edit properties if you wish. A Comment will be is created when you click button. Properties are consisted of two major categories - Attributes and Events. Attributes can be: - URL - Valid web address. - Image - Image has to be previously added to Project (Project Manager > Images). - File - File has to be previously added to Project (Project Manager > Other Files).
mikoBasic PRO for PIC32 First three event types can have one of the following three actions: 1. OpenUrl - Opens entered URL in default Web browser. 2. OpenFile - Opens a file within a default program associated with the file extension (defined by Windows). 3. None - Does nothing. The fourth event, OnMouseOver, has only 2 actions: 1. PreviewImage - Shows image when cursor is moved over a comment. 2. None - Does nothing. Attributes are tightly bounded with events.
mikroBasic PRO for PIC32 You can see the contents of the created XML file by expanding Active Comment Editor: As we mentioned above you can add image or file which are already included in project. If the the desired image or file aren't added, you can do it directly from here by clicking the 97 or button.
mikoBasic PRO for PIC32 Next file dialog will be opened: There, you should select the desired image to be added. In our example, Easy_GSM_GPRS.jpg image will be added.
mikroBasic PRO for PIC32 Now, when image has been selected, we can assign an event to it. For example, OnMouseOver will be used for PreviewImage action, and OnLeftClick + Alt will be assigned to OpenUrl action: Now we can save our changes to Active Comment by clicking the Save button. Note: Setting file attributes is same as for image, so it won't be explained separately.
mikoBasic PRO for PIC32 There is another way to add an active comment to an active project. You can do it simply by typing a comment in old fashion way, except with ac: prefix. So it would look like this: Notice that when you stop typing, Add Comment To Project button will show. By clicking on it, you will open Active Comment Editor and comment name will be already set, so you need only to adjust attributes and settings.
mikroBasic PRO for PIC32 If you click No, comment will be removed from the source code.
mikoBasic PRO for PIC32 Now click again Rename button. Now you have renamed your Active Comment in such a way that its filename, source code name are changed: Deleting Active Comment Deleting active comment works similar like renaming it. By clicking on delete button, you will remove an active comment from both code and Project Manager.
mikroBasic PRO for PIC32 Export Project This option is very convenient and finds its use in relocating your projects from one place to another (e.g. from your work computer to your home computer). Often, project contains complicated search paths (files involved within your project could be in a different folders, even on different hard disks), so it is very likely that some files will be forgotten during manual relocation.

mikroBasic PRO for PIC32 Regular Expressions Introduction Regular Expressions are a widely-used method of specifying patterns of text to search for. Special metacharacters allow you to specify, for instance, that a particular string you are looking for, occurs at the beginning, or end of a line, or contains n recurrences of a certain character. Simple matches Any single character matches itself, unless it is a metacharacter with a special meaning described below.
mikoBasic PRO for PIC32 Examples: count[aeiou]r finds strings 'countar', 'counter', etc. but not 'countbr', 'countcr', etc. count[^aeiou]r finds strings 'countbr', 'countcr', etc. but not 'countar', 'counter', etc. Within a list, the "-" character is used to specify a range, so that a-z represents all characters between "a" and "z", inclusive. If you want "-" itself to be a member of a class, put it at the start or end of the list, or precede it with a backslash.
mikroBasic PRO for PIC32 Metacharacters - Predefined classes \w - an alphanumeric character (including "_") \W - a nonalphanumeric character \d - a numeric character \D - a non-numeric character \s - any space (same as [\t\n\r\f]) \S - a non space You may use \w, \d and \s within custom character classes. Example: so on.
mikoBasic PRO for PIC32 Examples: count.*r ß- matches strings like 'counter', 'countelkjdflkj9r' and 'countr' count.+r - matches strings like 'counter', 'countelkjdflkj9r' but not 'countr' count.?r - matches strings like 'counter', 'countar' and 'countr' but not 'countelkj9r' counte{2}r - matches string 'counteer' counte{2,}r - matches strings like 'counteer', 'counteeer', 'counteeer' etc.

F7 Step Over Executes the current program line, then halts.
mikoBasic PRO for PIC32 mikroICD Debugger Example Here is a step-by-step mikroICD Debugger Example. First you have to write a program.
mikroBasic PRO for PIC32 After successful compilation and MCU programming press F9 to start the mikroICD. After the mikroICD initialization a blue active line should appear. We will debug the program line by line. Pressing [F8] we are executing code line by line. However, it is not recommended that user does not use Step Into [F7] and Step Over [F8] over Delays routines and routines containing delays. Instead use Run to cursor [F4] and Breakpoints functions.
mikoBasic PRO for PIC32 Step Into [F7], Step Over [F8] and Step Out [Ctrl+F8] are mikroICD debugger functions that are used in stepping mode. There is also a Real-Time mode supported by the mikroICD. Functions that are used in the Real-Time mode are Run/Pause Debugger [F6] and Run to cursor [F4]. Pressing F4 executes the code until the program reaches the cursor position line. Run(Pause) Debugger [F6] and Toggle Breakpoints [F5] are mikroICD debugger functions that are used in the RealTime mode.
mikroBasic PRO for PIC32 Breakpoints are divided into two groups: hardware and software breakpoints. The hardware breakpoints are placed in the MCU and provide fastest debugging. Number of hardware breakpoints is limited to 8 (6 instruction, 2 data). If all hardware brekpoints are used, then the next breakpoint will be software breakpoint. These breakpoints are placed inside the mikroICD and simulate hardware breakpoints. Software breakpoints are much slower than hardware breakpoints.

mikroBasic PRO for PIC32 CHAPTER 6 mikroBasic PRO for PIC32 Specifics The following topics cover the specifics of mikroBasic PRO for PIC32 compiler: - Basic Standard Issues - Predefined Globals and Constants - Accessing Individual Bits - Interrupts - Linker Directives - Built-in Routines - Code Optimization 133 MikroElektronika
mikoBasic PRO for PIC32 GOTO Table If a certain routine is allocated on the address higher than 64kB and can not be accessed directly, a GOTO table is created just after the Interrupt Vector Table to enable this routine call. GOTO table comprises of addresses of those routines that are allocated on the addresses higher than 64kB. So, whenever a call is made to a routine which is not directly accessible, it jumps to an assigned GOTO table block which contains address of a desired routine.
mikroBasic PRO for PIC32 - sbit - bit - iv Related topics: Keywords, PIC32 Specific Predefined Globals and Constants To facilitate PIC32 programming, the mikroBasic PRO for PIC32 implements a number of predefined globals and constants. All PIC32 SFRs are implicitly declared as global variables of volatile word. These identifiers have an external linkage, and are visible in the entire project. When creating a project, the mikroBasic PRO for PIC32 will include an appropriate (*.
mikoBasic PRO for PIC32 Accessing Individual Bits The mikroBasic PRO for PIC32 allows you to access individual bits of 16-bit variables. It also supports sbit and bit data types. Lets use the Zero bit as an example. This bit is defined in the definition file of the particular MCU as: const Z = 1 dim Z_bit as sbit at SR.B1 To access this bit in your code by its name, you can write something like this: ‘ Clear Zero Bit SR.
mikroBasic PRO for PIC32 See Predefined Globals and Constants for more information on register/bit names. sbit type The mikroBasic PRO for PIC32 compiler has sbit data type which provides access to registers, SFRs, variables, etc. You can declare a sbit varible in a unit in such way that it points to a specific bit in SFR register: module MyModule dim Abit as sbit sfr external ‘ Abit is precisely defined in some external file, for example in the main program unit ... implements .... end.
mikoBasic PRO for PIC32 at keyword You can use the keyword “at” to make an alias to a variable, for example, you can write a library without using register names, and later in the main program to define those registers, for example: module MyModule dim PORTAlias as byte external ‘ here in the library we can use its symbolic name ... implements ... end. program MyProgram ... dim PORTAlias byte as at PORTB ‘ this is where PORTAlias is fully defined ... main: ... end.
mikroBasic PRO for PIC32 Interrupts The PIC32MX generates interrupt requests in response to interrupt events from peripheral modules. The Interrupt module exists external to the CPU logic and prioritizes the interrupt events before presenting them to the CPU. The PIC32MX Interrupts module includes the following features: - Up to 96 interrupt sources. - Up to 64 interrupt vectors. - Single and Multi-Vector mode operations. - Five external interrupts with edge polarity control. - Interrupt proximity timer.
mikoBasic PRO for PIC32 Interrupt Priorities In the Multi Vector Mode, the user is able to assign a group priority and group subpriority level to each of the interrupt vectors. The user-selectable priority levels range from 1 (the lowest priority) to 7 (the highest). If an interrupt priority is set to zero, the interrupt vector is disabled for both interrupt and wake-up purposes. Interrupt vectors with a higher priority level preempt lower priority interrupts.
mikroBasic PRO for PIC32 where: - iv - reserved word that inform the compiler that it is an interrupt service routine. - IVT_ADC - appropriate Interrupt Vector. - ilevel 7 - Interrupt priority level 7. - ics Interrupt Context Saving; Interrupt Context Saving can be performed in several ways: 1. ICS_SOFT - Context saving is carried out by the software. 2. ICS_SRS - Shadow Register set is use for context saving. 3. ICS_OFF - No context saving 4.
mikoBasic PRO for PIC32 Interrupt Example Here is a simple example of handling the interrupts from Timer1 (if no other interrupts are allowed): program Timer1_interrupt sub procedure Timer1Int() iv IVT_TIMER_1 ilevel 7 ics ICS_SRS T1IF_bit = 0 ‘ Clear T1IF LATB = not PORTB ‘ Invert PORTB end sub main: AD1PCFG = 0xFFFF TRISB = 0 LATB = 0xAAAA ‘ Initialize AN pins as digital ‘ initialize PORTB as output ‘ Initialize PORTB value TMR1 = 0 PR1 = 65000 ‘ reset timer value to zero ‘ Load period register T1IP0_
mikroBasic PRO for PIC32 Linker Directives mikroBasic PRO for PIC32 uses internal algorithm to distribute objects within memory. If you need to have a variable or routine at the specific predefined address, use the linker directives absolute and org. When using these directives, be sure to use them in proper memory segments, i.e. for functions it is the KSEG0 and for variables it is the KSEG1. Linker directives are used with the virtual addresses.
mikoBasic PRO for PIC32 org directive can be used with main routine too. For example: program Led_Blinking main: org 0x800 ... end ‘ main procedure starts at 0x800 Directive orgall Use the orgall directive to specify the address above which all routines and constants will be placed. Example: main: orgall(0x200) ‘ All the routines, constants in main program will be above the address 0x200 ... end. Built-in Routines The mikroBasic PRO for PIC32 compiler provides a set of useful built-in utility functions.

The main features are: Constant folding All expressions that can be evaluated in the compile time (i.e. constant) are being replaced by their results.
mikroBasic PRO for PIC32 Single Static Assignment Optimization Introduction In compiler design, static single assignment form (often abbreviated as SSA form or SSA) is an intermediate representation (IR) in which every variable is assigned exactly once. An SSA-based compiler modifies the program representation so that every time a variable is assigned in the original program, a new version of the variable is created.
mikoBasic PRO for PIC32 0x9D000004 0x9D000008 L__SSA_Test7: 0x10400002 0x70000000 BEQ NOP R2, R0, L__SSA_Test2 Without SSA enabled, sub procedure SSA_Test this example is consisted of 5 asm instructions : ;Example.
mikroBasic PRO for PIC32 Asm code and SSA optimization If converting code from an earlier version of the compiler, which consists of mixed asm code with the C code, keep in mind that the generated code can substantially differ when SSA optimization option is enabled or disabled. This is due to the fact that SSA optimization uses certain working registers to store routine parameters (W10-W13), rather than storing them onto the function frame.
CHAPTER 7 mikoBasic PRO for PIC32 PIC32 Specifics In order to get the most from the mikroBasic PRO for PIC32 compiler, the user should be familiar with certain aspects of PIC32 MCU. This knowledge is not essential, but it can provide a better understanding of the PIC32’s capabilities and limitations, and their impact on the code writing as well.
mikroBasic PRO for PIC32 Types Efficiency First of all, the user should know that PIC32’s ALU, which performs arithmetic operations, is optimized for working with 32-bit types. Also, it performs hardware multiplication and division on the integer level, so the floating multiplication and division is slower and consumes more memory comparing it to the integer. The PIC32 supports 64-bit data types, but they are less efficient. They provide higher precision, but lack the code size and the execution.
mikoBasic PRO for PIC32 PIC32 Memory Organization The PIC32MX microcontrollers provide 4 GB of unified virtual memory address space. All memory regions, including program memory, data memory, SFRs and Configuration registers reside in this address space at their respective unique addresses. The program and data memories can be optionally partitioned into user and kernel memories. In addition, the data memory can be made executable, allowing the PIC32MX to execute from data memory.
mikroBasic PRO for PIC32 PIC32MX Memory Layout The PIC32MX microcontrollers implement two address spaces: virtual and physical. All hardware resources, such as program memory, data memory and peripherals, are located at their respective physical addresses. Peripherals, such as DMA and Flash controllers, use physical addresses and access memory independently of the CPU. Virtual addresses are exclusively used by the CPU to fetch and execute instructions.
mikoBasic PRO for PIC32 As it can be seem, the entire 4 GB virtual address space is divided into two primary regions: User and Kernel space. The lower 2 GB of space called USEG/KUSEG, and the upper 2 GB are divided into KSEG0, KSEG1, KSEG2 and KSEG3. Virtual vs Physical Addresses The PIC32MX’s CPU uses virtual addresses to address the peripherals, which means that to access the PIC32MX’s peripherals we (and the CPU) must be operating within the virtual boundaries of KSEG1.
mikroBasic PRO for PIC32 Memory Type Specifiers The mikroBasic PRO for PIC32 supports usage of all memory areas. Each variable may be explicitly assigned to a specific memory space by including a memory type specifier in the declaration, or implicitly assigned. The following memory type specifiers can be used: - code - data - rx (reserved for compiler purposes only) - sfr code Description The code memory type may be used for allocating constants in program memory.
mikoBasic PRO for PIC32 Read Modify Write Problem The Microchip microcontrollers use a sequence known as Read-Modify-Write (RMW) when changing an output state (1 or 0) on a pin. This can cause unexpected behavior under certain circumstances. When your program changes the state on a specific pin, for example RB0 in PORTB, the microcontroller first READs all 8 bits of the PORTB register which represents the states of all 8 pins in PORTB (RB7-RB0). The microcontroller then stores this data in the MCU.
mikroBasic PRO for PIC32 Actual voltage levels on MCU pins are relevant. MODIFY Data is modified to set the RB0 bit: WRITE PORTB is written with the modified data. The output driver for RB0 turns on, and the capacitor starts to charge: The second line, PORTB.
mikoBasic PRO for PIC32 To correct the problem in the code, insert a delay after each PORTB.Bx = 1 line, or modify the entire PORTB register in a single line PORTB = 0b00000011. This problem can be avoided by using LATx register when writing to ports, rather than using PORTx registers. Writing to a LATx register is equivalent to writing to a PORTx register, but readings from LATx registers return the data value held in the port latch, regardless of the state of the actual pin.
mikroBasic PRO for PIC32 The second line, LATB.B1 = 1; will be decoded like in this way: READ LATB is read: STORE Since the voltage levels on MCU pins are no longer relevant, we get the expected value: Actual voltage levels on MCU pins are no longer relevant when using LATx for output MODIFY Data is modified to set the bit: WRITE LATB is written with the new data.

mikoBasic PRO for PIC32 Whitespace Whitespace is a collective name given to spaces (blanks), horizontal and vertical tabs, newline characters and comments. Whitespace can serve to indicate where tokens start and end, but beyond this function, any surplus whitespace is discarded. For example, two sequences dim tmp as byte dim j as word and dim dim tmp j as as byte word are lexically equivalent and parse identically.
mikroBasic PRO for PIC32 Comments Comments are pieces of text used to annotate a program, and are technically another form of whitespace. Comments are for the programmer’s use only; they are stripped from the source text before parsing. Use the apostrophe to create a comment: ‘ Any text between an apostrophe and the end of the ‘ line constitutes a comment. May span one line only. There are no multi-line comments in mikroBasic PRO for PIC32.
mikroBasic PRO for PIC32 Literals Literals are tokens representing fixed numeric or character values. The data type of a constant is deduced by the compiler using such clues as numeric value and format used in the source code. Long and Unsigned Suffixes Integral values can be represented in decimal, hexadecimal or binary notation. In decimal notation, numerals are represented as a sequence of digits (without commas, spaces or dots), with optional prefix + or - operator to indicate the sign.
mikoBasic PRO for PIC32 Character Literals Character literal is one character from the extended ASCII character set, enclosed with quotes (for example, “A”). Character literal can be assigned to variables of byte and char type (variable of byte will be assigned the ASCII value of the character). Also, you can assign character literal to a string variable. String Literals String literal is a sequence of characters from the extended ASCII character set, enclosed with quotes.
mikoBasic PRO for PIC32 Keywords Keywords are special-purpose words which cannot be used as normal identifier names. Beside standard BASIC keywords, all relevant SFR are defined as global variables and represent reserved words that cannot be redefined (for example: P0, TMR1, T1CON, etc). Probe Code Assistant for specific letters (Ctrl+Space in Editor) or refer to Predefined Globals and Constants.

You can replace them by your own definitions, if you plan to develop your own libraries. For more information, see mikroBasic PRO for PIC32 Libraries.
mikoBasic PRO for PIC32 Uniqueness and Scope Although identifier names are arbitrary (within the rules stated), errors result if the same name is used for more than one identifier within the same scope. Simply, duplicate names are illegal within the same scope. For more information, refer to Scope and Visibility. Identifier Examples Here are some valid identifiers: temperature_V1 Pressure no_hit dat2string SUM3 _vtext … and here are some invalid identifiers: 7temp %higher int j23.07.
mikroBasic PRO for PIC32 Parentheses Parentheses ( ) are used to group expressions, isolate conditional expressions, and indicate function calls and function parameters: d = c * (a + b) if (d = z) then ... func() sub function func2(dim n as word) ‘ ‘ ‘ ‘ Override normal precedence Useful with conditional statements Function call, no arguments Function declaration w/ parameters For more information, refer to Operators Precedence and Associativity, Expressions and Functions and Procedures.
mikoBasic PRO for PIC32 Program Organization mikroBasic PRO for PIC32 imposes strict program organization. Below you can find models for writing legible and organized source files. For more information on file inclusion and scope, refer to Modules and to Scope and Visibility. Organization of Main Module Basically, the main source file has two sections: declaration and program body. Declarations should be in their proper place in the code, organized in an orderly manner.
mikroBasic PRO for PIC32 Organization of Other Modules Modules other than main start with the keyword module. Implementation section starts with the keyword implements. Follow the model presented below: module include ‘******************************************************** ‘* Interface (globals): ‘******************************************************** ‘ symbols declarations symbol ... ‘ constants declarations const ... ‘ structures declarations structure ...
mikoBasic PRO for PIC32 ‘ functions declarations sub function sub_function_name([dim byref] [const] ParamName as [^]type, [dim byref] [const] ParamName2, ParamName3 as [^]type) as [^]type [ilevel 0x123] [overload] [forward] ... end sub end. Note: Sub functions and sub procedures must have the same declarations in the interface and implementation section. Otherwise, compiler will report an error.
mikroBasic PRO for PIC32 Name Spaces Name space is a scope within which an identifier must be unique. The mikroBasic PRO for PIC32 uses two distinct categories of identifiers: 1. Global variables are visible throughout the whole unit, from the place of declaration. Also. they can be seen in other units, if they are declared above the Implementation section. 2. Local variables, parameters, types, function results - must be unique within the block in which they are declared.
mikoBasic PRO for PIC32 Here’s an example: program MyProgram include “utils” include “strings” include “MyUnit” ... For the given module name, the compiler will check for the presence of .emcl and .mbas files, in order specified by search paths. - If both .mbas and .emcl files are found, the compiler will check their dates and include the newer one in the project. If the .mbas file is newer than the .emcl, then .mbas file will be recompiled and new .emcl will be created, overwriting the old .emcl.
mikroBasic PRO for PIC32 Interface Section Part of the module above the keyword implements is referred to as interface section. Here, you can place global declarations (constants, variables, labels, routines, structures) for the project. Do not define routines in the interface section. Instead, state the prototypes of routines (from implementation section) that you want to be visible outside the module. Prototypes must exactly match the declarations.
mikoBasic PRO for PIC32 For example, lets create a project which will calculate circle area and will have sub function and sub procedure definition in two different modules, and a call to these routines in the third, separate module. So, the project will be consisted of the main module, Main_Module.mpas and First_Module.mpas and Second_ Module.mpas modules. In the Main_Module we will define routine called r_squared (calculates radius squared).
mikroBasic PRO for PIC32 sub procedure CircleArea() ‘ Definition of the CircleArea routine dim res as real res = r_square(5) ‘ Calculate r*r pi_r_square(res) ‘ Calculate pi*r*r end sub end. Variables and PIC32 Every declared variable consumes part of RAM memory. Data type of variable determines not only the allowed range of values, but also the space a variable occupies in RAM memory. Bear in mind that operations using different types of variables take different time to be completed.
mikoBasic PRO for PIC32 Labels Labels serve as targets for goto and gosub statements. Mark the desired statement with label and colon like this: label_identifier : statement No special declaration of label is necessary in mikroBasic PRO for PIC32. Name of the label needs to be a valid identifier. The labeled statement and goto/gosub statement must belong to the same block. Hence it is not possible to jump into or out of routine. Do not mark more than one statement in a block with the same label.
mikroBasic PRO for PIC32 ‘... main: if cnt > MAXALLOWED then cnt = 0 PORT.1 = 0 MYDELAY end if Note: Symbols do not support macro expansion in a way the C preprocessor does. Functions and Procedures Functions and procedures, collectively referred to as routines, are subprograms (self-contained statement blocks) which perform a certain task based on a number of input parameters. When executed, a function returns value while procedure does not.
mikoBasic PRO for PIC32 Function calls are considered to be primary expressions and can be used in situations where expression is expected. A function call can also be a self-contained statement and in that case the return value is discarded.
mikroBasic PRO for PIC32 Example Here’s an example procedure which transforms its input time parameters, preparing them for output on Lcd: sub procedure time_prep(dim byref sec, min, sec = ((sec and $F0) >> 4)*10 + (sec and min = ((min and $F0) >> 4)*10 + (min and hr = ((hr and $F0) >> 4)*10 + (hr and end sub hr as byte) $0F) $0F) $0F) A function can return a complex type. Follow the example bellow to learn how to declare and use a function which returns a complex type.
mikoBasic PRO for PIC32 program Volume dim Volume as word sub function First(dim a as word, dim b as word) as word forward sub function Second(dim c as word) as word dim tmp as word tmp = First(2, 3) result = tmp * c end sub sub function First(dim a, b as word) as word result = a * b end sub main: Volume = Second(4) end. Functions reentrancy Functions reentrancy is allowed. Remember that the PIC32 have memory limitations that can vary between MCUs.
mikroBasic PRO for PIC32 Types Basic is strictly typed language, which means that every variable and constant need to have a strictly defined type, known at the time of compilation. The type serves: - to determine the correct memory allocation required, - to interpret the bit patterns found in the object during subsequent accesses, - in many type-checking situations, to ensure that illegal assignments are trapped.
mikoBasic PRO for PIC32 Derived Types The derived types are also known as structured types. They are used as elements in creating more complex userdefined types. The derived types include: - arrays - pointers - structures Arrays An array represents an indexed collection of elements of the same type (called the base type). Since each element has a unique index, arrays, unlike sets, can meaningfully contain the same value more than once.
mikroBasic PRO for PIC32 The number of assigned values must not exceed the specified length. Vice versa is possible, when the trailing “excess” elements will be assigned zeroes. For more information on arrays of char, refer to Strings. Multi-dimensional Arrays Multidimensional arrays are constructed by declaring arrays of array type. These arrays are stored in memory in such way that the right most subscript changes fastest, i.e. arrays are stored “in rows”.
mikoBasic PRO for PIC32 Be careful when handling strings in this way, since overwriting the end of a string will cause an unpredictable behavior. Array of string is declared in this manner: typedef str as string[5] ‘ first, declare str as a string of 5 elements dim buffer as str[5] ‘ now, declare buffer as a array of str elements String Concatenating mikroBasic PRO for PIC32 allows you to concatenate strings by means of plus operator.
mikroBasic PRO for PIC32 Pointers A pointer is a data type which holds a memory address. While a variable accesses that memory address directly, a pointer can be thought of as a reference to that memory address. To declare a pointer data type, add a carat prefix (^) before type. For example, in order to create a pointer to an integer, write: ^integer In order to access data at the pointer’s memory location, add a carat after the variable name.
mikoBasic PRO for PIC32 This leads to equality of the following declarations: dim ptr1 as ^const byte ‘ ptr1 pointer in data space pointing to a byte in code space const ptr1 as ^byte ‘ ptr1 pointer in data space pointing to a byte in code space Therefore, when declaring a pointer within constant declaration block, const qualifier refers to pointed object, not to pointer itself. Notes: - Pointer to constant space (Flash memory) is allocated in RAM.
mikroBasic PRO for PIC32 Sample = MyPtr^(1, 2, 3) ‘ Perform function call via pointer, call Func1, the return value is 3 MyPtr = @Func2 ‘ MyPtr now points to Func2 Sample = MyPtr^(1, 2, 3) ‘ Perform function call via pointer, call Func2, the return value is 5 MyPtr = @Func3 ‘ MyPtr now points to Func3 Sample = MyPtr^(1, 2, 3) ‘ Perform function call via pointer, call Func3, the return value is 0 end. @ Operator The @ operator constructs a pointer to its operand.
mikoBasic PRO for PIC32 Pointer Arithmetic Pointer arithmetic in the mikroBasic PRO for PIC32 is limited to: - assigning one pointer to another, - comparing two pointers, - comparing pointer to zero, - adding/subtracting pointer and an integer value, - subtracting two pointers. Assignment and Comparison The simple assignment operator (=) can be used to assign value of one pointer to another if they are of the same type. Assigning the integer constant 0 to a pointer assigns a null pointer value to it.
mikroBasic PRO for PIC32 Pointer Addition You can use Inc to add an integral value to a pointer. The result of addition is defined only if the pointer points to an element of an array and if the result is a pointer pointing to the same array (or one element beyond it). If a pointer is declared to point to type, adding an integral value n to the pointer increments the pointer value by n * sizeof(type) as long as the pointer remains within the legal range (first element to one beyond the last element).
mikoBasic PRO for PIC32 For example: dim a as byte[10] ptr as ^byte ‘ array a containing 10 elements of type byte ‘ pointer to byte main: ptr = @a[6] ptr = ptr - 3 ptr^ = 6 Dec(ptr) end. ‘ ‘ ‘ ‘ ptr is pointer to byte, pointing to a[6] ptr-3 is a pointer pointing to a[3] a[3] now equals 6 ptr now points to the previous element of array a: a[2] Also, you may subtract two pointers.
mikroBasic PRO for PIC32 For example, the following declaration creates a structure type called Dot: structure Dot dim x as float dim y as float end structure Each Dot contains two members: x and y coordinates; memory is allocated when you instantiate the structure, like this: dim m, n as Dot This variable declaration creates two instances of Dot, called m and n. A member can be of the previously defined structure type.
mikoBasic PRO for PIC32 Types Conversions Conversion of variable of one type to a variable of another type is typecasting. mikroBasic PRO for PIC32 supports both implicit and explicit conversions for built-in types.
mikroBasic PRO for PIC32 Explicit Conversion Explicit conversion can be executed at any point by inserting type keyword (byte, word, short, integer, longint, or float) ahead of the expression to be converted. The expression must be enclosed in parentheses. Explicit conversion can be performed only on the operand left of the assignment operator. Special case is the conversion between signed and unsigned types.
mikoBasic PRO for PIC32 Typedef Specifier The specifier typedef introduces a synonym for a specified type. The typedef declarations are used to construct shorter or more convenient names for types already defined by the language or declared by the user. The specifier typedef stands first in the declaration: typedef synonym as The typedef keyword assigns synonym to . The synonym needs to be a valid identifier.
mikroBasic PRO for PIC32 Qualifier volatile The qualifier volatile implies that a variable may change its value during runtime independently from the program. Use the volatile modifier to indicate that a variable can be changed by a background routine, an interrupt routine, or I/O port. Declaring an object to be volatile warns the compiler not to make assumptions concerning the value of an object while evaluating expressions in which it occurs because the value could be changed at any moment.
mikoBasic PRO for PIC32 Arithmetic Operators Arithmetic operators are used to perform mathematical computations. They have numerical operands and return numerical results. Since the char operators are technically bytes, they can be also used as unsigned operands in arithmetic operations. All arithmetic operators associate from left to right.
mikroBasic PRO for PIC32 Relational Operators Use relational operators to test equality or inequality of expressions. All relational operators return TRUE or FALSE. All relational operators associate from left to right. Relational Operators Overview Operator Operation == equal <> not equal > greater than < less than >= greater than or equal <= less than or equal Relational Operators in Expressions The equal sign (=) can also be an assignment operator, depending on context.
mikoBasic PRO for PIC32 Bitwise Operators Use bitwise operators to modify individual bits of numerical operands. Bitwise operators associate from left to right. The only exception is the bitwise complement operator not which associates from right to left.
mikroBasic PRO for PIC32 Unsigned and Conversions If a number is converted from less complex to more complex data type, the upper bytes are filled with zeroes. If a number is converted from more complex to less complex data type, the data is simply truncated (the upper bytes are lost). For example: dim a dim b ‘ ...
mikoBasic PRO for PIC32 Boolean Operators Although mikroBasic PRO for PIC32 does not support boolean type, you have Boolean operators at your disposal for building complex conditional expressions. These operators conform to standard Boolean logic, and return either TRUE (all ones) or FALSE (zero): Operator Operation and logical AND xor logical exclusive OR (XOR) or logical OR not logical negation Unary Operators Unary operators are operators that take exactly one argument.
mikroBasic PRO for PIC32 See Pointers for more details on this subject Note: Besides these, sizeof and explicit conversion unary operators are supported also. Sizeof Operator The prefix unary operator sizeof returns an integer constant that represents the size of memory space (in bytes) used by its operand (determined by its type, with some exceptions). The operator sizeof can take either a type identifier or an unary expression as an operand.
mikoBasic PRO for PIC32 Expressions An expression is a sequence of operators, operands and punctuators that returns a value. The primary expressions include: literals, constants, variables and function calls. From them, using operators, more complex expressions can be created. Formally, expressions are defined recursively: subexpressions can be nested up to the limits of memory.
mikroBasic PRO for PIC32 if b*5 then... ‘ byte level - general rule will not give same result as a = b * 5 if a then... ‘ word level - general rule + left side exception if b*5 exceeds byte range. Explicit Typecasting Any expression can be evaluated at specific level by using explicit typecasting. Having in mind previous example, in order to get same calculation in conditional and assignment expression, the following should be done: if word(b*5) then...
mikoBasic PRO for PIC32 Conditional Statements Conditional or selection statements select one of alternative courses of action by testing certain values. There are two types of selection statements: - if - select case If Statement Use the keyword if to implement a conditional statement. The syntax of the if statement has the following form: if expression then statements [else other statements] end if When expression evaluates to true, statements execute. If expression is false, other statements execute.
mikroBasic PRO for PIC32 In order to force the compiler to interpret our example the other way around, we have to write it explicitly: if expression1 then if expression2 then statement1 end if else statement2 end if Select Case Statement Use the select case statement to pass control to a specific program branch, based on a certain condition. The select case statement consists of selector expression (condition) and list of possible values.
mikoBasic PRO for PIC32 Also, you can group values together for a match. Simply separate the items by commas: select case reg case 0 opmode = 0 case 1,2,3,4 opmode = 1 case 5,6,7 opmode = 2 end select Nested switch Note that the select case statements can be nested – values are then assigned to the innermost enclosing select case statement. Iteration Statements (Loops) Iteration statements let you loop a set of statements.
mikroBasic PRO for PIC32 If final_value is a complex expression whose value can not be calculated in compile time and number of loop iterations is not to be changed inside the loop by the means of final_value, it should be calculated outside the for statement and result should be passed as for statement’s final_value. statement_list is a list of statements that do not change the value of counter.
mikoBasic PRO for PIC32 Do Statement The do statement executes until the condition becomes true. The syntax of the do statement is: do statements loop until expression statements are executed repeatedly until expression evaluates true. expression is evaluated after each iteration, so the loop will execute statements at least once.
mikroBasic PRO for PIC32 end if Delay_ms(1000) wend ‘ Now we can work with CF card ...
mikoBasic PRO for PIC32 Here is a simple example: sub procedure Proc1() dim error as byte ... ‘ we’re doing something here if error = TRUE then return end if ... ‘ some code, which won’t be executed if error is true end sub Note: Return statements performs the same as exit statement except in functions. If breaking out of a function with return statement, return value will not be specified. In such cases exit statement should be used.
mikroBasic PRO for PIC32 Gosub Statement Use the gosub statement to unconditionally jump to a local label — for more information, refer to Labels. The syntax of the gosub statement is: gosub label_name ... label_name: ... return This will transfer control to the location of a local label specified by label_name. Also, the calling point is remembered. Upon encountering the return statement, program execution will continue with the next statement (line) after gosub.
mikoBasic PRO for PIC32 - Accessing local variable: _. - Accessing routine parameter: FARG__.
mikroBasic PRO for PIC32 Directives Directives are words of special significance which provide additional functionality regarding compilation and output. The following directives are at your disposal: - Compiler directives for conditional compilation, - Linker directives for object distribution in memory. Compiler Directives Any line in source code with leading # is taken as a compiler directive. The initial # can be preceded or followed by whitespace (excluding new lines).
mikoBasic PRO for PIC32 Here is an example: ‘ Uncomment the appropriate flag for your application: ‘#DEFINE resolution10 ‘#DEFINE resolution12 #IFDEF resolution10 THEN // #ELSE #IFDEF resolution12 THEN // #ELSE // #ENDIF #ENDIF Unlike #IFDEF, #IFNDEF checks if flag is not defined by means of #DEFINE, thus producing the opposite results.
mikroBasic PRO for PIC32 Explicit Path mikroBasic PRO for PIC32 uses internal algorithm to distribute objects within memory. If you need to have a variable or routine at the specific predefined address, use the linker directives absolute and org. When using these directives, be sure to use them in proper memory segments, i.e. for functions it is the KSEG0 and for variables it is the KSEG1. Linker directives are used with the virtual addresses.
mikoBasic PRO for PIC32 In first case, compiler will recognize your attempt, but in order to save Flash space, and boost performance, it will automatically replace all instances of this constant in code with it’s literal value. In the second case your constant will be placed in Flash in the exact location specified. To place a routine on a specific address in Flash memory you should write the following: sub procedure proc(dim par as word) org 0x9D000000 ‘ Procedure will start at the address 0x9D000000; ...

mikroBasic PRO for PIC32 CANSPI Library The SPI module is available with a number of the PIC32 MCUs. The mikroBasic PRO for PIC32 provides a library (driver) for working with mikroElektronika’s CANSPI Add-on boards (with MCP2515 or MCP2510) via SPI interface. The CAN is a very robust protocol that has error detection and signalization, self–checking and fault confinement.
