Simply enough, it's (basic) threads implemented on the Cortex M3 platform. It implements a basic round-robin TDB scheduler in pure C, using the program stack pointer (PSP) mechanism in the Cortex M3 platform.

This requires the CMSIS libraries to build, and has been tested using CodeSourcery compilers.

First, call thread_init to init the system. quantaUs specifies the time quanta in microseconds. Create a thread using thread_create(fnc) and kill it using thread_kill. Finally, call thread_go to set everything in motion. thread_go does not return - instead, use main as a bootstrap and use the first registered thread an your master routine.

A thread returning from its routine will cause a hard fault, this will be fixed in future.
