I'm a newcomer to this device and have been there and got started OK. A good intro seems to be a PC parallel plug to ISP interface. You can do this direct but it is preferable to add a buffer as this gives a little protection to PC and supposedly increases acceptable line lenght. (For best protection buy a cheap PC parallel card that can be replaced if you burn it.) This is 'serial' programming as it does the AVR bit-by-bit, parallel programming is more complex. This approach allows programming of many AVR devices from the humble 2313 upwards so it's not holding you to a specific device. It's also compatible with Atmel's and others programming software/IDE. I bought a cable for 11GBP with a SMT driver in the parallel hood as I decided the parts would cost me nearly that. The header can then just go into pins on breadboard. You'll find a million links to this method if you google, eg: http://www.robotgames.net/atmel/Cables.htm You can buy boards set up like this and sometimes they are cheap on ebay: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=4660&item=3829753872&rd=1 Adrian ===== - ********************************************* ___________________________________________________________ALL-NEW Yahoo!
