Is it possible to set parameters other than RPM via UAVCAN on the Myxa controller, or is it only possible via telega? If it is, how do I do it, and are all the required data types part of the public regulated data types?
Yes. All configuration parameters are accessible via the standard service
Telega is the firmware that is executed on Myxa and Mitochondrik. It supports CAN, USB, and UART for communication; the last two interfaces are accessible via the Kucher GUI tool only.
You can use the UAVCAN GUI Tool.
