Re: [avr-gcc-list] moving from PIC to AVR...

[Larry Barello]

Start with the application notes at www.atmel.com?

All the things you want to do are easily supported in GCC and most
assemblers.

You can look over my web site as I use all those techniques, but I
don't have simple code snippets for you to look at.  Best to go to
atmel, drill down to 8 bit RISC software and look over their examples.

For examples of how to do this in C (That is what GCC is all about!)
look at www.avrfreaks.net in the faqs/coding guides under GCC.

Oh, and of course, read the chip data sheet and become familiar with
the instructions.
