Mid-Range PIC C Programming Tutorials

The following tutorials build on the material covered in the mid-range assembler tutorial series, showing how to implement the example applications from those lessons, using Microchip's XC8 C compiler (running in "Free mode").

To get the most out of these lessons, you should purchase the Gooligum baseline and mid-range training and development board, which was designed to complement this tutorial series.

Note: PIC12F629 Programming Issues
Workarounds for a couple of issues you may encounter as you work through the first lessons, especially if you are using a PICkit 2 programmer

1: Basic Digital I/O Introducing XC8 Using delay loops to flash an LED, reading and debouncing simple switches, and using weak pull-ups on mid-range PICs Updated 14/9/12	L1 source
2: Using Timer0 Configuring and accessing Timer0 Using Timer0 for debouncing, background tasks, event timing and counting (with an example of C macros) Updated 16/9/12	L2 source
3: Introduction to Interrupts Interrupt service routines, Timer0 and external interrupts, debouncing Updated 17/9/12	L3 source
4: IOC, Sleep Mode and the Watchdog Timer Using interrupt-on-change, sleep mode, and the watchdog timer Updated 17/9/12	L4 source
5: Reset, Power and Clock Options Oscillator (clock) modes, power-on reset and brown-out detection Updated 17/9/12	L5 source

Additional lessons included with the Gooligum training board
