I can recomend I built a couple of these and they work great! I can recommend this project for anyone who wants a really cheap USB-LCD connection. You can find the mega8 controller VERY cheap on Ebay if you look around for a while and buy like 20 of them. I got them for 1 euro each in that quantity a while back. The whole interface will cost you less than 3 euro :) I built a couple of these and they work great! I can recomend I built a couple of these and they work great!

So the technical answer would be, Yes. Although C would most likely have the greatest flexibility, likely having the most available libraries already available. Ret:

Still, I'd agree with tyler - PICs have a nice USB framework, including demo software that acts like a serial port. It's easy to hack up. Pretty neat – I haven’t seen USB done in software only.

just a suggestion, might it be easier to use a pic with onboard usb (like http://www.sparkfun.com/commerce/product_info.php?products_id=231 ) to reduce the components list, or use a normal pic or avr and a FTDI chip (like the design you also linked to) to do the uart to usb conversion, which i believe now has most of the components except for a couple of capacitors built-in to it.

Get datasheets and stuff from atmel's own website. GCC+GAS compiles fine as an avr cross-compiler and cross-assembler/linker (if you're under windows it's probably easier to find a precompiled binary somewhere though). Avrdude, uavrisp and ponyprog are common loader programs, and you can get programmers and prototyping boards from places like sparkfun and olimex, or just wire some up yourself if you feel like it. At least one guy from Atmel hangs out on comp.arch.embedded and will sometimes answer your more abstruse questions. avrfreaks ( http://www.avrfreaks.net/ ) is the site everybody recommends, but I’ve never really gotten into that site.

Does anyone have a good link for where I should go to get started? I’ve always been interesting in getting in to Atmega development.
