Important :

• It is assumed that MPLAB® and USB drivers for MPLAB® ICD 2 Debugger are previously installed.
• Procedure described below is also relevant for MPLAB® ICD 3 Debugger.
• Be sure to import compiled .hex file prior to importing .cof file, because it contains configuration bit settings which are essential for the proper functioning of the user code.

To successfully use MPLAB® ICD 2 Debugger with generated .cof file, follow the steps below :

1. First of all, start mikroC PRO for PIC and open the desired project.
2. Open Tools › Options › Output settings, and check the "Generate COFF file" option, and click the OK button.
3. Next, enable Background Debug bit in the Edit Project menu.
4. After that, compile the project by pressing Ctrl + F9.
5. Connect USB cable and turn on power supply on EasyPIC6.
6. Program the MCU by pressing F11.
7. Connect external power supply, USB cable from PC and modular interface cable to the MPLAB® ICD 2 Debugger's appropiate sockets, like on the picture below :



8. Connect second end of the modular interface cable to the EXT ICD (RJ12) socket of EasyPIC6 :



9. Picture below illustrates the proper connection of ICD 2 to EasyPIC6 :



10. Next, open MPLAB®, and select the appropriate device by choosing Configure › Select Device... For example, 16F887 MCU will be selected :



11. After device selection, click on the File › Import. Open file dialog box should appear. Then, go to the project folder and open the generated HEX file, UART.hex.
  Note : This is very important, because hex file contains configuration bit settings which are essential for the proper functioning of the user code.
12. Next, click the File › Import. Open file dialog box should appear. Then, go to the project folder and open the generated COFF file, UART.cof :



13. Then, select the MPLAB® ICD 2 from the Debugger › Select Tool menu for hardware debugging :



14. Complete the MPLAB® ICD 2 Setup Wizard from the Debugger menu (if needed).
15. After completing MPLAB® ICD 2 Setup Wizard, click on the Debugger › Connect :



16. Finally, click on the Debugger › Program :



17. Now, you can start debugging the code by clicking Step Over button on the Debug toolbar, or by pressing F8 :
