How to Connect Two RA Devices on the Same CAN Bus (Part 2)

Learn how we use the Controller Area Network Flexible Data‑Rate (CAN FD) peripheral on the RA6M5 Evaluation Kit to exchange classical Controller Area Network (CAN) frames between two RA devices. In this video, we configure the RA6M5 kit to receive incoming frames through First‑In, First‑Out (FIFO) message buffers, store the data, and transmit the frames back using common FIFO buffers. The RA6M5 Evaluation Kit includes an on‑board CAN FD transceiver, enabling direct communication on a shared CAN bus.
