CAN communication between two NUCELO-F446RE ?

[KBumS]

Hello! I'm using two STM32F446RE (NUCELO-64) boards through CAN communication, we want to perform CAN operation with one slave as master.

How do I know how to ensure that CUBEMX is communicating with each other?

Hello, 

Even this is an old topic, this is my answer (in case someone else is landing at this post:)

1- There is no master/slave concept in CAN protocol. Any CAN node on the bus is a transmitter or receiver without any permission of another CAN node on the bus.

2- Check out these knowledge base articles:
