kaOS ATmega32 Operating System
From Circuit Cellar's AVR Contest
Author: Nicholas Clark & Adam Liechty
kaOS is a real-time, multithreaded, preemptive operating system for the ATmega32 microcontroller, which loads and executes programs from a Secure Digital or MMC card. The system waits for you to insert a card and press the Reset button, at which point a program is loaded from the card and executed. The system supports multiple threads, cross-thread messaging, dynamic memory allocation, dynamic thread creation, semaphores and much more.
