Hi Everyone- I posted part of this on the Blue Robotics Forum, but no one over at BR has a Pixhawk 4 so they encouraged me to post my problem here. Any help is much appreciated.
I recently bought 2 x T200 and 2 x Basic ESCs that I want to use in skid steering with a Holybro Pixhawk 4 running ArduRover. For Tx/Rx I am using a FrSky X9 Lite and a X8R.
I configured everything in QGroundControl and here is a list of parameters that I’ve changed.
SERVO1_FUNCTION = 73
SERVO1_FUNCTION = 74
Currently, I have the ESCs connected to the Holybro FP07 power distribution board (motors 1 and 3) but I am not getting any response from the T200s.
When I apply power, the ESCs beep, but then absolutely nothing happens when I arm and move the sticks on the transmitter. I have calibrated the X9, both on the transmitter side and in QGC. I also tried setting subtrims so that PWM from channels 1 and 3 range exactly from 1100 to 1900. Still nothing from the T200s.
My question then- is this a power distribution issue, or something else? Before I unsolder the ESCs from the PDB and connect directly to the battery I thought I would get some feedback.
