A simple parallel port programmer using 74HCT244 will do. If you prefer com port, check out PonyProg or other AVR ISP compatible programmer as well. Please also check the great AVR-GCC (WinAvr under windows). The AVRfreaks (Http://www.avrfreaks.com) website is nice as well. Please also consider subscribe to AVR-GCC and AVR-LIBC mailing list. People there are very helpful even though you get so much traffic as here. Highly recommended. Actually you do not even need a programmer, check out this website. http://www.siwawi.arubi.uni-kl.de/avr_projects/ With AVRs getting cheaper and cheaper than PICs, I think I will need to check AVRs as well since my colleagues in Germany are using AVRs exclusively.

ATMEL was kind enough to give me an AVR Butterfly. It has a 6 terminal ISP connector. Is there a simple programmer I can put together for it? The AVR device on it is an atmega169. I'll also need some software to drive the programmer. I know if I do defect I'll need to get an STK500 and/or an ICE, but for now I just want to blink the LCD or beep the speaker. Any links/suggestions? Thanks, Bob -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
