 A microcontroller running barebones -- or with something like FreeRTOS
(two tasks, with priority set as needed)?.

 Especially as Linux is not the most "real-time" OS available; I don't
even know if an RT kernel is available for the R-Pi (Beaglebones have had
RT kernel builds, but they aren't the default install).
