I’d like to see a DC motor controller with CAN bus coms. Have it possible to set up the device ID over usb along with any out bound message formats.
Sending a 2 or 3 byte message to the devices ID will set the direction and speed. Very similar to the current serial/uart coms spec. Also the ability to output Vin, Current, speed, ect as a preselected output message would alow for some monitoring of whats happening with the control board.
