Testing CAN Protocol on STM32L476G evaluation board

Hi,
I’m using the STM32L76G evaluation board and would like to work with the CAN protocol. I have a DB9 connector but no slave devices. Could you suggest how I can test and work with CAN in this setup?

Hello,

You can simply use CAN in Loopback mode. You don't need for a second node to establish a CAN bus with transceivers:

You can also probe Tx frames on CAN Tx pin.

You can inspire from this example: https://github.com/STMicroelectronics/STM32CubeF4/tree/master/Projects/STM324xG_EVAL/Examples/CAN/CAN_LoopBack

Hope that answered your question.
