I am trying to sned a RC message using offboard board for a 8 channel RC signal. however, this was not possible. Hence I have setup a SITL with keyboard based joystick for PX4 to check the reading over the RC topic in mavros over the topic
I am reading the values over the mavros and the values looks like this :
[900, 900, temp0, 1750, Throttle , temp1, temp2, PITCH, 1750,0, 0, 0, 0, 0, 0, 0 ]
These values were taken in stabilised mode.
On the keyboard when I change Roll or YAW, I see
temp0, temp1, and temp2 varying.
PITCH is mapped to pitch on keyboard and
Throttle to Throttle.
My questions are as follows:
- Could anybody tell me how to convert this 16 channel RC input into 8 channel RC input?
- Why there are 3 values mapped to ROLL and YAW?
- What do other constant values 900 and 1750 suggest?
Thanks in Advance
