M5Stack Dial CAN Arduino Library

  • Re: M5StampS3 / M5Dial and CAN

    For anyone still looking for a CAN solution for the M5Dial using the Arduino IDE, checkout the ESP32-TWAI-CAN.hpp library. I'm using the M5 CANBus Unit(CA-IS3050G) SKU: U085 connected to port B. Using the sample code with the library I simply changed the GPIO pins TX = 2 RX = 1 and set the desired bus speed. It works a treat for me for sending CAN frames from the dial.
