Sombody tried to use the Frsky PPM receiver with success?

I don't have such a receiver to test it... Do you have a scope?

No, unfortunately not...
But maybe this could help? It is the manual with a picture showing some scope-similar information

Hmm sorry, seems like the way it should be...
Without a frsky receiver it will be hard for me to find out the problem
You'll have to use PWM

The Frsky CPPM Signal has High level 3,3V and Low level 0V.
One Frame is only 18ms long. So it is possible, that the overlong startpulse is shorter than a channel pulse, if all the channels have long pulses at the same time. you can mesure from rising edge to rising edge or from faling edge to falling edge, it should be the same.
