I am currently building a S-BUS to PPM encoder. I got the basic code working and tested on APM2 and KK2 board. (not in flight but looks good on radio calibration page)
I am wondering it it better to keep the signal chain in digital form rather than going from S-BUS(digital) to PPM (analog) then on the APM, PPM (analog) back to digital (APM) then PWM (analog) out to esc /servos.
I think it might be possible to code a S-BUS to i2c convertor and make Arducopter read the value off the i2c bus.
Hope to get some comments here before I send the board out, I did make provision for i2c on the PCB but will take it out to save space if it is not feasible.
Also is anyone is already working on 1?
Hi, did you manage to get it working? can you share it with us?
