TM4C OS

Purpose

tm4c_os is an operating system that is (for now) specifically written the Texas Instrument TM4C123GH6PM micro-controller. It is a combination of a desktop operating system and a small embedded operating system.

The goal is to create an operating system that is guaranteed to keep running even if one of the tasks accesses the wrong memory or overflows its stack.

Results

Improved skill in writing makefiles with auto dependencies and automatically compiling new files

Future Work

After looking back at this work, I've realized it would be far more valuable as a portable, standalone, lightweight kernel (smaller and less complex than FreeRTOS). Sometimes, for a small embedded project where there is no heap, a small kernel is preferred over the main loop method or a state machine, especially one where you can customize scheduling strategies.
