STM32H7 CAN-FD using CAN 2.0 transceivers.

Hi, 

  I'm thinking in replace  a STM32F7 with a STM32H7 on two board that has normal CAN-2.0 transceivers. I would like to know if it will work for CAN-FD frames, keeping the baud below 1 Mbps.

Hi

Mendes.Ari

‌,

Both CAN modules (FDCAN1 and FDCAN2) are compliant with ISO 11898-1 (CAN protocol specification version 2.0 part A, B) and CAN FD protocol specification version 1.0.

This is what we say in

http://www.st.com/content/ccc/resource/technical/document/datasheet/group3/23/be/db/eb/29/39/4b/eb/DM00387108/files/DM00387pdf/jcr:content/translations/en.DM00387pdf

.

So, the configuration you want to setup for FDCAN should work properly.

The above links are no longer valid. Please update. Very interested in understanding the migration path from an F7 to H7.
