STM32F413 Third CANBUS

[erdinc]

Hello,

I'm planning to use the STM32F413VGT3 in my project. It says it has three CAN buses. Can I use these three lines independently? Some of my research (ChatGPT) indicates that the third CAN line is not a standard CAN bus. I'd appreciate any clarification on this matter.

Best regards.

The differences between the three CAN instances are listed here:

Thanks for the information.

I can use all three buses at the same time, is that correct?

Hello @erdinc ,

You can use the three CAN instances independently.

CAN3 is a standard CAN 2.0B interface exact replication of CAN1 and it is independent from CAN1/CAN2. CAN2 is slave to CAN1 from architectural point of view (not from protocol standpoint).

Hope that answers your question.
