Arduino Uno Q have CANFD controller. I would like to use it as standard CAN 2.0 controller. I didn’t find any example code how to use UNO Q STM32U585 CANFD controller.

Hi @ismo_paavola

Currently, CAN on the MCU of the Uno Q is not supported by the Arduino Zephyr Core.

It should be supported by the Zephyr RTOS, though: if you are familiar with it, you may want to give it a spin: [zephyr/samples/drivers/can at main · zephyrproject-rtos/zephyr · GitHub](https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/drivers/can) .

Cheers.

Did you get it working on Arduino Uno Q? @ismo_paavola
