The pin of FDCAN1, 2 does not exist on STM32h745/50 Discovery Board.

Hello Community,

I would like to receive and transmit the data via FDCAN.

However, I cannot find the real pin on the STM32h745/50 Discovery Board.

The Microcontroller pin of FDCAN1_RX is PH14, PA11, PD0, PB8, and PI9.

The Microcontroller pin of FDCAN1_TX is PB9, PA12, PD1, and PH13.

 

However, the pins cannot be found on the STM32h745/50 Discovery Board.So, how could I use the FDCAN1,2 pin and function...?

Hi

I hope I can help with something. I believe, the microcontroller output pin configuration would be PH13 for TX and PH14 for RX for FDCAN1, but from this output it goes to the CAN driver U22, hence the output to HCAN and LCAN would have to be through CN11.Best regards
