Any news on CAN Bus - STM32F103

[silardg]

I have been searching for a good supported CAN library for the STM32F103 (Bluepill).

I have found that there are supporting functions here for the CAN interface, but I'm not sure how to access them or use them.

I have been digging into the files to understand it better.
I have found this define, where including the above referenced code is commented out.

If I uncomment it, will I be able to access it somehow?

Hi @silardg
Currently, it is not supported.
Anyway you can enable it and code it yourself using the HAL.
One other solution is to use Roger core which has a CAN library:

Looks like CAN is still disabled for the Blue-Pill (https://github.com/stm32duino/Arduino_Core_STM32/blob/master/variants/BLUEPILL_F103XX/stm32f1xx_hal_conf.h#L55)

Is there any plan to add official CAN support for the Blue-Pill?

Currently no plan as I've a lot of stuff to do 😕
I know @geosmall do some dev around CAN:

Close this one to track all CAN request on the same issue #259.
Mark it as duplicated.
