FreeRTOS Ported to Raspberry Pi
This provides a very basic port of FreeRTOS to Raspberry pi.
Raspberry Pi expansion Board
This provides drivers and a simple API used to control a board developed in the project for the Embedded Systems course.
The demo program in "Demo/main.c" exemplifies the use of the library to control some of the components.
Documentation for the board can be found in:

Howto Build
Type make! -- If you get an error then:
$ cd .dbuild/pretty
$ chmod +x *.py
Currently the makefile expect an arm-none-eabi- toolchain in the path. Either export the path to yours or modify the TOOLCHAIN variable in dbuild.config.mk file.
You may also need to modify the library locations in the Makefile:
kernel.elf: LDFLAGS += -L"c:/yagarto/lib/gcc/arm-none-eabi/4.7.1/" -lgcc
kernel.elf: LDFLAGS += -L"c:/yagarto/arm-none-eabi/lib/" -lc
The build system also expects find your python interpreter by using /usr/bin/env python, if this doesn't work you will get problems.
To resolve this, modify the #! lines in the .dbuild/pretty/*.py files.
