[Paparazzi-devel] Reply for the ppm encoder problem

[Chris]

Well the ppm type definition is now in the radio file not in the 
airframe file:
<!DOCTYPE radio SYSTEM "radio.dtd">
<radio name="Aurora_bomb_dc" data_min="800" data_max="2200" 
sync_min="5000" sync_max="17000" pulse_type="POSITIVE">
Also make sure that your throttle channel (if you have a futaba) does 
not exceed 2ms otherwise this will put the encoder in to simulating a 
signal loss condition (no ppm output).
Reverse the throttle channel of your rc transmitter and see what happens 
(with the propeller removed of course!!!)
When you power up the system the encoder must blink @ ~3Hz assuming that 
the rc transmitter is already powered on, if it is not blinking but the 
led is always on this means that it doesn't see any servo signals.
Also make sure that the jumper on the ppm board is bridged if you don't 
power the receiver from a different pack.
Normally when you power up the autopilot and the transmitter is off then 
the led stays on all the time.
When you power on the rc transmitter (not recommended you should always 
have the rc transmitter
powered on before you power on the autopilot) the led should blink at 
3Hz rate.
If you now turn off the rc transmitter simulating a signal loss the led 
should blink at ~1Hz rate.
After that if you power on the rc transmitter again the led should blink 
at 3Hz again.
About me i am killing my self slowly but surely at work as my project is 
going well and
the funds keep coming :-) I work almost 16 hours per day including 
weekends that's why i am
away for so long.
