The setup includes :
- Pixahawk 6c
- Holybro M8N can bus gps
- T-motor 600Hz PWM ESC (tmotor AIR 40A)
- T-motor MN5008 motors
- 915 Mhz telemetry module
- frsky TARANIS X9D PLUS transmitter and receiver (R8XR)
- Holybro PM07 power module
- TAROT X8 octa-copter frame
The ESC refuse to calibrate after the procedure prescribed for ESC tuning in mission planner is followed .ESC’s have a periodic beep when they are not calibrated according to the T-motor documentation .When Esc are connected and calibration is attempted it does not respond even if the ESC are manually calibrated with a servo tester or the receiver and then connected to the Pixahwk they lose Calibration. I suspected the IO port on Pixahawk wasn’t enabled but on checking the parameters list it is enabled.
Any diagnosis is Helpful.
SIDE NOTE:
THIS SETUP WORKS PERFECTLY WITH PX4 AND QGROUND CONTROL JUST THE PID TUNING IS REQUIRED.
