Re: [Paparazzi-devel] MeekPE PPM encoder Problem.

Well thanks very much for now, I will check for it and if needed send some results...

Really appreciate. Later!

Felizardo.

You will need an oscilloscope preferably with dual inputs to detect which pulse (servo channel) is sent first. If several pulses are sent simultaneously you can not use MeekPE unfortunately but need a recent version of ppmencoder @ 20mhz.

If the combined pulse is not valid (not the correct min and max or wrong nr of channels or repeat time), paparazzi will not accept it

I think u missunderstood me, we were using a Spektrum radio without the MeekPE board (using only the satellite receiver directly). and now we dont have this Spektrum anymore and we are trying to set the new radio, but because it doesnt have a satellite receiver we need the MeekPE and its not working properly.

Cheers Felizardo.

Hi,
(Christophe you're right) MeekPE can only be used with receivers that output their pulses one after each other. But it already make it work with a Spektrum one in the past.
If i remember correctly, on some Spektrum receiver, servo connector arrangement in not related to the channel order : first position connector is not necessarily channel one and next connector position doesn't mean next channel number.
Oscilloscope is your friend :)

Does MeekPE work with spectrum? Please correct me if I am wrong but I thought it could only be used with receivers that output their pulses one after each other like any 35MHz but like almost no digital receiver.

 Hi there everyone.

 I had to change from spektrum radio to a chinese generic one. So we made a MeekPE PPM Encoder Board, with all set as the page of the enconder describes. but the PPM signal refuses to show up on pprz, we did some tests on the osciloscope and we could see the signals leaving the ppm board towards lisa. Any ideas on what might be wrong?

ps.: channel 6 in the radio is supose to be the mode selector.
