Hello ALL

In order to perform a new project using STM32F302VC micro-controller . I have a question , :

it s possible  to activate the CAN controller in standard and extended configuration (CAN 2.0A and CAN2.0B) in the same  time . 'using only one CAN controller ' ?

if yes there is any code example provide this config?

Thanks in Advance.

The STM32 implementations can do pattern matching up to 32-bits, so you can do 11-bit ID matching, or 29-bit Extended ID, matching so I'm not sure there is an issue here. You set the filter(s) up to do the job you need it too. You can also fully construct the packets being sent.

Review the CAN section in the Reference Manual, and determine if it does what you need. I've demonstrated filter here several times.
