This project is intended as an interface between a Serial Port USB and TFT320x240 and PPM for easily connecting companion computers to APM.
It enables a client to draw and write on an attached LCD screen and change PPM values, its designed to be fast and reliable and with a failsafe on the PPM output so if the USB was disconnected or the software did not send a timely update to any PPM channel, it will switch to a preset failsafe. Ofcurse if the module lost power, the APM should enter failsafe as well.
THIS PROJECT IS EXPERIMENTAL AND UNTESTED AND INTENDED ONLY FOR EDUCATIONAL PURPOSES
