CAN - Don't get RXMSG

[Giovanni]

Hi,

You should look into the AFIO section of the STM32 Reference Manual.

You can remap to PB8 & PB9 with the following

Code: Select all

AFIO->MAPR |= AFIO_MAPR_CAN_REMAP_REMAP2;

Also you need to set up CAN_BTR register according to your APB bus frequency
There is a special online calculator to do this trick.
