Just a quick heads-up for other newbies like me: Pascal Stang has written a library for AVR microprocessors, Procyon AVRlib. It hasn't been updated since some mid-2006, but a quick look through the code shows that this guy knew what he was doing. The code is well-written, organized, and GPLed. It provides software emulation of some devices your AVR might not have (ATmega168 doesn't have the Intel memory bus -- which is what I was after), there's a simple networking stack, IDE/ATA interface, MMC/SD, GPS, servo, LCD drivers and other whatnots. Hopefully it will be of some help to at least a few people on here.

so far all the links are broken

This is the only one left i think

d-tools.cvs.sourceforge.net

Thanks kle8309 for the active link. I got it and unzipped it. It makes a AVRlib folder.

Now what do I do with it. I am not a very advanced programmer in fact I have never assembled a

project using anything but the default tools but this really looks interesting from waywards's description.

Thanks again,

Ralph
