I’m trying to set up CAN communication to my ODrive S1 (latest version) from a NUCLEO-G474RE with a Seeed Studio CAN-BUS shield. The CAN communication is not working. One of the things that could be causing it is that the termination resistors are not set correctly, as in the docs, there is this section:
(CAN Bus Guide — ODrive Documentation 0.6.11 documentation)
“If your ODrive is the “last” (furthest) device on the bus, you can use the on-board 120 Ohm termination resistor by switching the DIP switch to “CAN 120R”. Otherwise, add an external resistor. The nominal bus resistance should be 60 ohms between CANH and CANL.”
Where can I find this DIP switch?
