To our valued customers From the day one, we in MikroElektronika gave ourselves the highest possible goals in pursuit of excellence. That same day, the idea of EasyPIC™ development board was born. And we all grew together with EasyPIC™. In its each and tiniest piece we had put all of our energy, creativity and sense of what’s best for an engineer. I’ve personally assembled hundreds of early EasyPIC™ boards myself with my home soldering iron. EasyPIC PRO™ follows the same path.

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.
connectivity Input/Output Group One of the most distinctive features of EasyPIC PRO™ v7 are it’s Input/Output PORT groups. They add so much to the connectivity potential of the board.
connectivity Headers Buttons LEDs With enhanced connectivity as one of the key features of EasyPIC PRO™ v7, we have provided two connection headers for each PORT. I/O PORT group contains one male IDC10 2x5 header (like CN22 Figure 6-3). There is one more IDC10 header available on the right side of the board, next to DIP switches. These headers are all compatible with over 70 MikroElektronika accessory boards, and enable simple connection.
connectivity 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 ADC click™ RFiD click™ BlueTooth click™ MP3 click™ GSM click™ Click Boards are plug-n-play! ™ MikroElektronika portfolio of over 200 accessory boards is now enriched by an additional set of mikroBUS™ compatible Click Boards™. Almost each month several new Click boards™ are released.
communication UART via RS-232 Enabling RS-232 In order to enable RS-232 communication, you must push SW5.3 (RG1) and SW5.4 (RG2) to ON position. This connects the RX and TX lines to appropriate microcontroller pins and its second UART module. 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 fullduplex communication.
Enabling USB-UART communication UART via USB Modern PC computers, laptops and notebooks are no longer equpped with RS-232 connectors and UART controllers. They are nowdays replaced with USB connectors and USB controllers. Still, certain technology enables UART communication to be done over USB connection. Controllers such as FT232RL from FTDI® convert UART signals to the appropriate USB standard. In order to use USB-UART module on EasyPIC PRO™ v7, you must first install FTDI drivers on your computer.
communication USB device communication Enabling USB DATA BUS USB is the acronym for Universal Serial Bus. This is a very popular industry standard that defines cables, connectors and protocols used for communication and power supply between computers and other devices. EasyPIC PRO™ v7 contains USB DEVICE connector (CN9) which enables microcontrollers that support USB communication to establish a connection with the target host (eg. PC, Laptop, etc).
communication Ethernet is a popular computer networking technology for local area networks (LAN). Systems communicating over Ethernet divide a stream of data into individual packets called frames. Each frame contains source and destination addresses and errorchecking data so that damaged data can be detected and re-transmitted.
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 PRO™ 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.
DATA BUS Graphical Liquid Crystal Displays, or GLCDs are used to display monochromatic graphical content, such as text, images, human-machine interfaces and other content. EasyPIC PRO™ v7 provides the connector and necessary interface for supporting GLCD with resolution of 128x64 pixels, driven by the KS108 or similar display controller. Communication with the display module is done through CN16 display connector.
displays Touchpanel controller Touchpanel 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 touchpanels can be used as an input devices. EasyPIC PRO™ v7 is equipped with touchpanel controller and connector for 4-wire resistive touchpanels.
Piezoelectricity 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 piezoelectricity is the production of sound generators, called piezo buzzers. Piezo buzzer is an electric component that comes in different shapes and sizes, which can be used to create sound waves when provided with analog electrical signal.
other 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.
other 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 lineary dependent on the input voltage value.
I C EEPROM Enabling I2C EEPROM Figure 19-1: Activate SW5.7 and SW5.8 switches to enable pull-up resistors in I2C lines of Serial EEPROM. In order to connect I2C EEPROM to the microcontroller you must enable SW5.7 and SW5.8 switches, as shown on Figure 19-1. 4K7 pull-up resistors necessary for I2C communication are already provided on SDA and SCL lines once switches are turned on.
other modules Output voltages EasyPIC PRO™ v7 contains two additional pairs of screw terminals which can be used to get power supply output for your external devices. There are two available output voltages: 5V and 3.3V. Depending on which power source you use (adapter, laboratory power supply, or USB), maximum output currents can vary. Power consumption of the onboard modules can also affect maximum output power which can be drawn out of the screw terminals.
EasyPIC PRO™ v7 contains three GND pins located in three different sections of the board, which allow you to easily connect oscilloscope GND reference when you monitor signals on microcontroller pins, or signals of on-board modules. 1 GND is located next to the RS-232 connector. 2 GND is located right to the piezo buzzer, next to PORTA header. 3 GND is located above PORTJ I/O group, next to PORTF header.
