[Paparazzi-devel] PPM Tiny Input

[Rui Costa]

Hello,

 

I have the Futaba FP-R116FB 6 Channel FM 35MHz receiver. I test it in oscilloscope and get something like the picture in attach.

 

So, my connections are ok:

The problem appears to be in the radio.xml file.

 

 

<!DOCTYPE radio SYSTEM "radio.dtd">
 <radio name="cockpitMM" data_min="900" data_max="2100" sync_min ="5000" sync_max ="15000">
 <channel ctl="1" function="ROLL"     min="2000" neutral="1498" max="1000" average="0"/>
 ...
 <channel ctl="2" function="MODE"     min="2000" neutral="1500" max="1000" average="1"/>
 </radio>

 

 

My file is like above. Maybe I have to change the values of the second line.

 

I notice on oscilloscope that my period is only 11ms instead of 20ms.

What can I do to make this work with tiny?
