>> 12f675 I've used cc5x (free version) to make 12f675 code. Worked fine. There are several C compilers that have 'free' versions that produce a limited amount of code for a limited number of processors; they're about equally expensive as basic compilers for 'real' versions (for that matter, I'm pretty sure that there are free versions of some of the basic compilers as well.) See here: http://www.piclist.com/techref/microchip/languages.htm Also consider JAL, a language somewhere between C, Basic, and Pascal, fully free and open source compiler...
