Setting up the arduino environment to use chibios is very simple. I am starting a new repository since this version is not backward compatible with the previous libraries. The arduino ide and environment has many drivers and libraries available within an arms reach, but the arduino environment is limited to just setup and loop and doesnt support multitasking effectively this is a simple, easy to use and robust freertos implementation that can just shim into the arduino ide as a library and allow the use of the best parts of both environments, seamlessly. Only few external components are needed as the course concentrates on teaching the actual programming language. Initializer, this function just initializes an object and can be invoked before the kernel is initialized. The arduino uno atmega328 has a single hardware serial connection. This hardware allows the atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer. Is there any advantage in using the arduino ide if you are not interested in existing arduino libraries and software. This function is implicitly invoked by halinit, there is no need to explicitly initialize the driver.
