microcontroller Programming

The AVR 8-Bit RISC Microcontroller from Atmel is a very common Microcontroller It's a single integrated circuit with EEPROM, Ram, Analog to Digital converter, a lot of digital input and output lines, timers, UART for RS 232 communication and many other things.

The best is however that a complete programming environment is available under Linux: You can program this Microcontroller in C using GCC. In this article I will explain how to install and use GCC. I will as well explain how to load the software into the Microcontroller. All you need for this are an AT90S4433 Microcontroller, a 4Mhz crystal, some cable and a few other very cheap parts.
