APM planner tells me the RC is not turned on and I see nothing on the slider bars.
This is for a RaspberryPi2 with the latest EMLID image (20160212) for the Navio2.
PPM encoder seems to be working, scope shows 0 to 3.5v pulses. For the 4 channels connected the 4 pulse widths change with stick movement (0 - 12ms within the frame). I have a large “blank” space (12ms to 25ms) where the encoder is obviously expecting input channels 5-8. Is this the problem? Or should it be a 5V output?
Then ls. This is where you’ll see the channels. You can look into your problem a little bit by moving sticks and checking if the values you see in the directory you just issued you command in, do match. I’d be very surprised if they don’t.
