Unable to Use USB while using CAN in STM32F103

deepakelango05 · ‎2024-04-17

I am using CAN peripheral and for debugging I am using USB-CDC to receive the status of the CAN transfers and Reception.

The issue I am facing is The USB was recognized as Virtual Port when Only USB was initialized and used but when Implemented with CAN the Virtual port had failed to get recognized.

Is there a way to overcome this problem?

Hello,

You cannot use CAN with USB at the same time on STM32F103 devices as they are sharing the same RAM.
