[Paparazzi-devel] PPM encoder : channels not responding when moving stic

Hello everyone,
I have a problem with my PPM encoder: when I move quickly a stick (or a
switch) from neutral to high value (regardless signal length in ms with an
oscillo on input channel), the encoder is not able to reproduce the good
pulse on output: the pulse for this channel generated by the encoder in the
frame stay to a value between neutral and high value.
If I move slowly: it's OK.
If I move slowly or quickly from neutral to low-value: it's always good.
I have the flash version v4.3 (it was the same problem with 4.1)

Is someone have found the same problem?
I test it with a MPX MC3000 and 3 RX (pico 4/5, RX7 synth DS/IPD and PCM10)
and it's the same.

Thanks' for yours answers

Ps: I have an other problem with this board, the channel 8 is not well
generated on output (signal is good on input pin PD7 but not taken in count
on output: always generated with neutral value???)
