Well, this might be the right moment to make clear I am a EE student in my second year, having just a little experience in asm, even less in C (more in Java, but that's irrelevant I guess) and about two months experience with PICs, not even related to my courses :o) My 'development environment' consists of: Linux box 300 MHz, using gputils (assembler MPASM compatible) and gpsim Parallel port programmer made in 10 minutes using parts from a dead ATX supply (hardwired for 16F62[78], but I guess it's compatible with others too) Standard soldering equipment Cheap DMM So I have to do a lot of paper design first, because I don't have much parts "on the shelf" and that makes it difficult to extend projects later. Being a student defines me to be a cheapskate, I guess (Also, I'm dutch, so...) Don't expect too much from me, if you are planing to build one (as for the parts, I only have a 16F628 ATM, not even a crystal or cap with a known value. (lots of caps with unknown values) ).
