For C++, 971 puts the hardware interface code in a separate process and uses custom message passing to communicate the hardware state to the control loops, etc. We can then write the hardware interface code once, test it on the hardware, and then move on. We are able to then write unit tests which simulate the hardware and generate messages with simulated sensors and physics. This allows us to do all our controls development before the hardware has been finished.
