I'm trying to send and receive messages trough CAN between Portenta C33 Mid Carrier with integrated CAN controller and a Raspberry PI with RS485 CAN HAT from Waveshare.
I've set up CAN on Raspberry using Waveshare's instructions (https://www.waveshare.com/wiki/RS485_CAN_HAT).
I'm trying to use example sketches provided with C33 to send and receive messages between Arduino and Raspberry, but nothing seems to get through.
I've connected CAN0 (the only CAN port) on Raspberry's CAN extension board with CAN1 with transciever on Arduino. When I send messages on loopback in Raspberry console, it seems to be working, so I assume something with communication with those two devices is wrong. Any suggestions?
