CAN1 communication doesnt work

Mr4 · ‎2024-02-23

Hi I'm very new in working with CAN-bus. My project involves two stm32 boards (both are nucleo-l433rc-p) and I want to get CAN-bus communication between them. The code is supposed to make a build in LED blink each time the blue button on the main nucleo board is pressed (although I would be happy to get any CAN communication at all).

Relevant code:

CAN Rx (PA11) is on CN7-3. You currently have your CAN transceiver Rx on CN7-6 which is PB13.

I was told that if a devices starts to smoke, put the smoke back in. I guess I never got all the smoke because the device never worked afterwards.
Don't worry, I won't byte.
