PPM Input instead of 4 or 5 cables from receiver?

Posted by Justin on August 21, 2011 at 6:40pm

Has anyone looked at doing PPM input to the ArduPilotMega instead of 4 or 5 channels of PWM?

I looked a the radio code AP_RC.cpp, and it seems to be using the same timer/interrupt that has been used on a different board to successfully read and decode PPM.

Would decoding a PPM stream be no more intensive than decoding 4 or 5 channels of PWM?
