Need help connecting AD0505 to an Orange Cube autopilot

Hi.

I’m trying to connect a AD0505C0 to a Pixhawk Orange Cube running Arducopter.

CANBUS has already been setup. (when using DRONECAN GUI, I can see other CANBUS devices messages (GPS/SERVO, ETC…) when plugged in.

once I plug in the ESC (it is powered on by a seperate DC power supply at 14V with common GND) nothing happens.

The small CANBUS LEDs blink once in a while along with the green LED…

120 ohm was measured while everything is turned off while connected to the cube…

Any thoughts ?

Could you please try with Telega v0? Here is the guide Updating AmpDrive firmware using Yukon

@koko did you ever figure this out?

Likely this is a protocol mismatch. AD0505C0 speaks Cyphal/Telega v1 by default, while ArduPilot Orange Cube expects DroneCAN, so the ESC will stay silent on that bus.

Quick path to make it work with Cube:

  1. Connect via Yukon and flash Telega v0 (DroneCAN).
  2. After reboot, assign a unique node-ID and verify the ESC appears in DroneCAN GUI.
  3. Keep one CAN bus speed everywhere (typically 1 Mbit/s) and exactly two 120-ohm terminations on the whole bus.
  4. Power check: CAN-H/CAN-L + common GND with FC; if using separate power, share ground (you already do) and verify CAN polarity.

Once on Telega v0, the ESC should enumerate normally in ArduPilot. If it still does not, share a screenshot from DroneCAN GUI node list and we can pinpoint the bus issue quickly.
