Posted on September 08, 2014 at 10:25Hi,In all examples I can find (ST Std driver library, STM32CubeF4, STM32CubeMX...) the CAN RX Pin is always configured regarding GPIO as Alternate Push/Pull Pin (Output) like the CAN TX Pin. I would expect the CA...

Posted on March 30, 2015 at 14:22Hi, I hope you (aka ''ABCD'') have figured out the CAN1/CAN2 filtering by now, but in case others can benefit: I ran into similar problems when configuring the filter settings using the ST HAL for the second CAN-bus ...
