I am attempting to get ESC telemetry on my quadcopter with a Pixhawk Cube Orange FC.
The ESCs are running BLHeli32 32.9, FC firmware is Arducopter 4.2.2.
I have tried two different approaches, with no success.
For both approaches there is a single wire spliced to all four separate ESCs, connected to the telemetry output.
The ESC appear to be sending telemetry information, but none is actually shown in Mission Planner.
I connected the telemetry connection to the RX port on Serial1 on the Pixhawk FC.
I set parameters as shown in the instructions: BLHeli32 and BLHeli_S ESCs — Copter documentation
SERIAL1_PROTOCOL = 16
Others left as default.
I could probe the signal on the telemetry wire and see the signal change if I throttled the motors, but I could not see any telemetry information in Mission Planner.
I attempted to connect the ESC telemetry via MatekL431-Dshot DroneCan to UART adapter.
I plugged the adapter into CAN port 1.
I set up the parameters as seen in the attached parameter file.
CANBUS.param (16.8 KB)
The adapter is visible in DroneCAN GUI, and I can see status packages being received from the ESC in the DroneCAN interface, but again there is no ESC data in Mission Planner.
I’m sure I’ve just missed something simple.
Any help would be really appreciated.
