I have posted the latest code from the work Rich and I have done for our microcontroller class at Cornell. We are releasing all of our code under the GPL license so feel free to use it, modify it, and have fun with it. The code is modified C code and assembly language for the Atmel Mega32 chip running on an STK500 board. It should be easily available from Atmel or perhaps your local electronic hobbyist shop.

If you go to my main page, you can see where I have added a new section, C code from a class I’m taking this semester. We’re making a lot of really cool designs based upon the Atmel CPU, which is readily available for those who like to tinker. I’ve put up my first project, a reaction time tester. It has the user push a button, waits approximately two seconds plus a random amount to keep the user from guessing, and then displays the user’s reaction time. It also keeps the user from cheating by detecting if they are holding the button down.
