best c compiler avr
Just now I'm deciding what to use as a main C compiler for AVR and what I can say based in what I've played is:
IAR
Pro: OK for medium-big-HUGE, or if you plan to work in various uP (ARM/PIC/AVR)
Con: not very user friendly, no appwizards, expensive
ICC
pro: OK for little-medium, user friendly, lot of code in the web, appwizard
con: project support
GNU:
pro:gnu
con: cmdline
I like ICC, I think IAR will be more useful in a long time basis
Only my 2c, you know.
