Hello there, experimenting with the EK-RA6M4 CAN example while its connected to an ESP32 and MCP2515 transceiver. Below is the error i got on RTT viewer:
For this example to work you will need 2 different RA boards with 1 CAN transceiver connected to each board. Not sure how ESP32 comes into place.
Other option if you have only 1 board and 1 CAN transceiver is to test in external loopback mode, where the Tx pin is transmitting to Rx pin via the transceiver.
The ESP32 can act as a CAN target and has a CAN transceiver. But two RA boards would work.
Thansk Larry, i figured it out, i just had to match the baudrates.
