Re: [Paparazzi-devel] ATMMega PPM Encoder

Then either the PPM polarity in the radio file is wrong or the radio 
file does not have 8 channels declared.
Do me a favor and put a 1k resistor and a led in series to the ppm 
output in order
to check if there is actually an output signal (the led will blink very 
fast but it is visible.
The led has polarity so try both ways there is no problem doing that.
You could also use an oscilloscope if you have.
