pic18f4620 xc8 compiler bundle

Here’s a small (5.2 MB) bundle that I use to compile and program c code on my pic18f4620 using a pickit2 on my PC. I’ve only tested this on XP.

It doesn’t have all the features of a full blown IDE like MPLABX (no stepping through code I’m afraid) but is a nice concise package that encourages the use of command line scripting.

Getting Started

  • Download the zip file on to your PC or, preferably, a USB key
  • Extract the files to a folder on your PC or USB key

The extracted folder contains the xc8 compiler files (modified to work with the pic18f4620 only), the pk2cmd software tool which is used to communicate with the PICkit2, and Notepad++, which can be used to write and modify code.

To create a new project do the following:

        1. First create a new folder inside the “robosumo_files” folder and copy the build.bat file into that folder.
        2.  Run the Notepad++  editor and paste the example code (flashing LED) given below. Save the code in the new folder as a file called “main.c” (don’t include quotes in the filename).
        3. Make sure the PICkit2 programmer is correctly connected to the PIC18f4620 and finally double click the build.bat file.
        4. If there are no errors in the code and the hardware is set up correctly then the PIC18f4620 will be programmed.

Example Code – Flashing LED

This is a pared back example program for the PIC18F4620. It blinks an LED connected to pin 19 (RD0). See this circuit

int main(void)
{
	// Make RD0 a digital output
	TRISD = 0b11111110;

	while(1)
	{
		LATDbits.LATD0 = 1; // Set pin RD0 high
		_delay(125000);     // 0.5 second delay
		LATDbits.LATD0 = 0; // Set pin RD0 low
		_delay(125000);     // 0.5 second delay
	}
}
