Check servo wiring issue #182

Closed tsaoyu closed 7 years ago

tsaoyu commented 7 years ago

We found rudder servo do not work properly in autonomous mode, maybe it is worthwhile to use logic analyser to check what happen to rudder servo control.

We think this is probably a bad connection at the RPI gpio pins.

Interesting, especially combined with the weird IMU issues we had. Maybe its time to move on from the free flying wiring?

28/02/17 conclusion: the rudder servo pin connection seems a bit dodgy. We got weird PWM readings once when shaking the RPi, which we couldn't replicate later on.

Changed the wire and seems fine now
