Re: [Paparazzi-devel] PPM Encoder and Lisa/L

[Jochen Rieger]

In the radio file is also just configure 6 channels(6 channel receiver). I wanted just say that is the 8 channel PPM encoder from Hendrix.

You have 6 zero's in the rc-message view, while the encoder sends 8 channels? That sounds like a radio.xml not being compatible with the number of pulses?

Note that paparazzi PPM reading is very selective. This dates from the time where everyone was using 35MHz. If 2 transmitters were on the same frequency, you wanted to be sure that paparazzi would not accept this corrupted signal.

Hello,

i have a problem with the PPM at Lisa/L. I can see an signal at PPM output of the 8 Channel PPM Encoder Version 2, that seems to be a PPM signal(measured with scope). The input port of the PPM signal is the Trig. port of UART1 at Lisa/L (pin 1).
But when I set the tele_FBW to 1 in GCS. I see only 0,0,0,0,0,0  in the value message window.

I have setup the radio file like the wiki. The right pulse_type and the right numbers of input channelns.
Have anyone an idea?

Best regards.
Jochen
