Hi. I have a STM32F429 Nucleo-144 board connected to a Trinamic PD60-4H-1378 stepper motor loaded with CANOpen firmware. I have adapted the CANOpen code from Jexbat which compiles well. I am very new to the subject of CANOpen and am not able to figure out how to talk to the stepper motor. For a start, i don't know what the NodeID of the motor is, nor the bit rate. All i see on the DSO is a signal, which seems to be a heartbeat signal from the motor (see pic). I get this even when STM32 is disconnected....
