Mostly C, with some basic java and perl thrown in.


Atmel firmware, PCB layout

    It is using DTR to control the RESET line, but they did not hook up RTS to control P0.14 (BSL). I duplicated the DTR/RESET circuit (D1, R1, R2, Q1), for RST/BSL using through hole parts, and removed R5. Now I don’t need to reach over and flip the switch every time I program a chip. lpc21isp takes care of all the switch flipping. That gives me the functionality of the aeolus programmer at half the price.

No public wish lists :(
