Much hype has been made over the last couple of years about UVCAN components to work with Ardupilot. I know Hitec launched a range of servos with much fan-fare but I can not find a supplier that stocks them anywhere.
Has anyone got any up to date recommendations for small canbus based servos and ESCs?
Thanks for the comments, will have a look at the hitec offerings and see if I can order some samples to experiment with.
@ppoirier Would welcome any further advice you have on making the system more resilient. Had planned on sorting a proper power bus but not sure what options there are for redundant data links as most of the servos only have one bus.
@davidbitton Those do look really interesting, have you tried them yet? Any idea if its possible to use a node for more than one purpose concurrently? Looks like it could get much simplify a lot of the wiring on larger aircraft.
Thanks, really helpful. I now have three of these nodes on my desk. Have managed to get one servo working and can edit the node parameters within DRONECAN GUI
Some pretty basic questions but I can’t find any documentation.
How do I edit the file highlighted above and compile it?
Is there any limit on the number of nodes in a system provided they all have unique nIDs?
If I wanted to connect a mavlink telem radio or rangefinder to one of the serial ports what code changes or parameter shance is needed within the file?
Am I right in assuming that the flight controller does not gain additional serial ports using these nodes it just allows them to be not plugged directly into the cube?
Does anyone have servos working on the L431 in the meantime ?
Mine have arrived, but as described in this thread (Matek l431 - pwm out) the servos do not want to be moved.
I have done the same, CAN_D1_UC_SRV_BM to 31 (Bitmask Servo 1-5)
and set the servo_functions in MP and DroneCAN Gui to identical aileron/rudder/elevator functions.
Thanks for the help. I have set everything as you have done. Unfortunately, the servo still does not work on the L431 (HW 438, SW 1.3.8C8682C0).
Matek H743(V1) - Plane 4.2.0
I will probably try the whole thing on a Pixhawk and with a second L431.
