programming mikroICD - In Circuit Debugger ™ What is Debugging? Every developer comes to a point where he has to monitor the code execution in order to find errors in the code, or simply to see if everything is going as planed. This hunt for bugs, or errors in the code is called debugging.
Here is a short overview of which debugging commands are supported in mikroElektronika compilers. You can see what each command does, and what are their shortcuts when you are in debugging mode. It will give you some general picture of what your debugger can do. Toolbar Icon Command Name Shortcut Description Start Debugger [F9] Starts Debugger. Run/Pause Debugger [F6] Run/Pause Debugger. Stop Debugger [Ctrl + F2] Stops Debugger. Step Into [F7] Executes the current program line, then halts.
The UART (universal asynchronous receiver/transmitter) is one of the most common ways of exchanging data between the MCU and peripheral components. It is a serial protocol with separate transmit and receive lines, and can be used for full-duplex communication. Both sides must be initialized with the same baud rate, otherwise the data will not be received correctly. Enabling RS-232 RS-232 serial communication is performed through a 9-pin SUB-D connector and the microcontroller UART module.
Modern PC computers, laptops and notebooks are no longer equipped with RS-232 connectors and UART controllers. They are nowadays replaced with USB connectors and USB controllers. Still, certain technology enables UART communication to be done via USB connection. FT232RL from FTDI® convert UART signals to the appropriate USB standard. In order to use USB-UART module on EasyPIC™ v7, you must first install FTDI drivers on your computer.
communication USB connection USB connector (CN4) which enables microcontrollers that support USB communication to establish a connection with the target host (eg. PC, Laptop, etc). Selection of communication lines is done using jumpers J12 or J18, depending on the target microcontroller.
mikroBUS sockets Easier connectivity and simple configuration are imperative in modern electronic devices. Success of the USB standard comes from it’s simplicity of usage and high and reliable data transfer rates. As we in mikroElektronika see it, Plug-and-Play devices with minimum settings are the future in embedded world too.

connectivity Input/Output Group One of the most distinctive features of EasyPIC™ v7 are it’s Input/Output PORT groups. They add so much to the connectivity potential of the board. Everything is grouped together PORT headers, PORT buttons and PORT LEDs are next to each other, and grouped together. It makes development easier, and the entire EasyPIC™ v7 Figure 10-1: I/O group contains PORT headers, tri-state pull cleaner and well organized.
connectivity Headers Buttons LEDs With enhanced connectivity as one of the key features of EasyPIC v7, we have provided four connection headers for each PORT. I/O PORT group contains two male IDC10 headers (like CN10 and CN15 on Figure 10-3). These headers are all compatible with over 70 mikroElektronika accessory boards, and enable simple connection. There is one more IDC10 header available on the left side of the board, next to the section with displays.
displays LCD 2x16 characters Liquid Crystal Displays or LCDs are cheap and popular way of representing information to the end user of some electronic device. Character LCDs can be used to represent standard and custom characters in the predefined number of fields. EasyPIC™ v7 provides the connector and the necessary interface for supporting 2x16 character LCDs in 4-bit mode. This type of display has two rows consisted of 16 character fields. Each field is a 7x5 pixel matrix.
Display connector is routed to PORTB (control lines) and PORTD (data lines) of the microcontroller sockets. Since the same ports are used by 2x16 character LCD display, you cannot use both displays simultaneously. You can control the display contrast using dedicated potentiometer P3. Full brightness display back light can be enabled with SW4.5 switch, and PWM-driven back light with SW4.6 switch.
displays Touch panel controller Touch panel is a glass panel whose surface is covered with two layers of resistive material. When the screen is pressed, the outer layer is pushed onto the inner layer and appropriate controllers can measure that pressure and pinpoint its location. This is how touch panels can be used as an input devices. EasyPIC™ v7 is equipped with touch panel controller and connector for 4-wire resistive touch panels.
To enable digit select lines for the 4-digit 7-segment display you have to turn on SW4.1, SW4.2, SW4.3 and SW4.4 switches. Digit select lines are connected to RA0 – RA3 pins on the microcontroller sockets, while data lines are connected to RD0 – RD7 pins. Make sure to disconnect other peripherals from the interface lines in order not to interfere with signal/data integrity.
modules DS1820 - Digital Temperature Sensor DS1820 is a digital temperature sensor that uses 1-wire® interface for it’s operation. It is capable of measuring temperatures within the range of -55 to 128°C, and provides ±0.5°C accuracy for temperatures within the range of -10 to 85°C. It requires 3V to 5.5V power supply for stable operation. It takes maximum of 750ms for the DS1820 to calculate temperature with 9-bit resolution.
The LM35 is a low-cost precision integrated-circuit temperature sensor, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ° Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. It has a linear +10.0 mV/°C scale factor and less than 60 μA current drain.
modules ADC inputs Digital signals have two discrete states, which are decoded as high and low, and interpreted as logic 1 and logic 0. Analog signals, on the other hand, are continuous, and can have any value within defined range. A/D converters are specialized circuits which can convert analog signals (voltages) into a digital representation, usually in form of an integer number. The value of this number is linearly dependent on the input voltage value.
I C EEPROM Figure 18-1: Activate SW4.7 and SW4.8 switches to connect microcontroller I2C lines to Serial EEPROM. In order to connect I2C EEPROM to the microcontroller you must enable SW4.7 and SW4.8 switches, as shown on Figure 18-1. 1kΩ pull-up resistors necessary for I2C communication are already provided on SDA and SCL lines once switches are turned on.
modules Piezo Buzzer Piezo electricity is the charge which accumulates in certain solid materials in response to mechanical pressure, but also providing the charge to the piezoelectric material causes it to physically deform. One of the most widely used applications of piezo electricity is the production of sound generators, called piezo buzzers.
