in reply to: Confirmation on Mixed CAN FD and Classical CAN Transmission Using FlexCAN0 #21745

Hi Tom,

Yes, the same controller can transmit both frame types without reconfiguration between transmissions, as long as all devices on the network are configured to receive CAN FD. Once CAN FD is enabled for CAN0, each individual message buffer can be set according to whether it is a CAN FD or classic CAN message. As a rule of thumb, use separate CAN Tx interrupt objects for each of your messages, especially between CAN FD and classic messages. By default, we set the baud rate of CAN0 to 500 kBaud, and the CAN FD rate to 2000 kBaud, but you can adjust those according to your requirements.

Ben
