Here is the issue :
RC9 is setup as pass-thru so I can see on the oscilloscope that the channel 9 from my receiver is forwarded to one of the output of the pixhawk.
1 - When the pixhawk is powered up and RC transmitter is off, the pixhawk output is down (not pwm signal) (so far so good)
2 - Then when the transmitter is on, the pwm signal is forwarded to the pixhawk output (so far so good)
3 - Then when the transmitter is switched off (equivalent to RC transmitter signal lost), a pwm signal (arround 1,9 ms) is still sent on the pixhawk output when I would expect to see no pwm signal anymore. (ISSUE !?)
So is it an issue or is there a way to define the default value of this output when the RC transmitter signal is lost ?
Thanks for your help !
