STM32F103C8T6 (Blue Pill) CAN BUS Communication

[Javier Parra]

Hi,

I´m trying to communicate two blue pills between them using CAN bus, but when I try to run it, it doesn´t even finish the start up, because I tried to use a blink program selecting the CAN in the .ioc and not using it and doesn´t work.

Does anyone knows why does this happen?

I just stumbled across this thread because, like many others, it deals with the Bluepill. For a long time now, only clones and counterfeits have been used on it, which can flash an LED but do not (cannot) support many other peripheral functions. I now strongly suspect that there is also a counterfeit on your Bluepill.

Are you 100% sure that it is an original STM32F103?

Please check websites like e.g. hackaday.io or eevblog.com.
