STM32CUBE F3 V1.10 CAN change?

[Bertrand1]

Hello,

Where I can find a list of change with this version about HAL_CAN. The compatibility has been broken but there is an exhaustive list of modification?

Thanks

Seem to recall seeing a post the other week breaking down the new CAN model and differences.

Hello @Bertrand​ ,

Please find below the main changes noted in the release note for the new HAL CAN driver:

CAN driver API's compatibility is broken:

• A new HAL CAN driver has been redesigned with new APIs, to bypass limitations on CAN Tx/Rx FIFO management present with previous HAL CAN driver version.
• The new HAL CAN driver is the recommended version. It is located as usual in Drivers/STM32F3xx_HAL_Driver/Src and Drivers/STM32F3xx_HAL_Driver/Inc folders. It can be enabled through switch HAL_CAN_MODULE_ENABLED in stm32f3xx_hal_conf.h
• The legacy HAL CAN driver is also present in the release in Drivers/STM32F3xx_HAL_Driver/Src/Legacy and Drivers/STM32F3xx_HAL_Driver/Inc/Legacy folders for software compatibility reasons. Its usage is not recommended as deprecated. It can however be enabled through switch HAL_CAN_LEGACY_MODULE_ENABLED in stm32f3xx_hal_conf.h

It would helpful to use a diff between the two versions to see the main changes.

Hope this helps you.

With Regards,

Imen

Thanks for your reply :

To Clive : Not enough familiar with this new forum to find any question about it. I will make more effort next time 😉

To ST : I have obviously read the release note but it is a bit weak to understand whats means "limitations of CAN FIFO...". In the same time, the data structure has change...

At the end, I spent time to use this version ( because of a bug of CubeMX where it is difficult ( or not possible!?)  to revert to a previous FW version. I am wondernig if I have not forget to implement something with this new version even it seems to work up to now.
