Hello,
I am looking to communicate between my control board and someone else's control board that is already designed via CAN communication. I am only looking to do Classic CAN communication (Not FD). I have the following parts:
MCU on my Control Board: STM32H7B3LIH6Q
MCU on coworkers Control Board: STM32F303RET
CAN Transceiver on both Control Boards: MCP2542WFD-E/SN
The STM32H7 controller can do both CAN 2.0B and CAN FD
The STM32F7 controller can only do CAN 2.0B
The CAN Transceiver, according to the datasheet, is a CAN FD Transceiver
If I want to communicate via CAN 2.0B (Classic CAN) and configure both controllers to Classic CAN, will the following connection scheme work:
STM32H7 -> FD CAN Transceiver -> FD CAN Transceiver -> STM32F7

should work perfect; just do not forget termination resistors on connection line.
