Hi all,
I'm using MCP2515 for a CAN application in the NUCLEO STM32WL board. I've managed to get it to work in pulling mode, however, I want to use interrupt mode.
For what I looked, I just have to enable the MCP interrupt pin in EXTI mode in cubeMX, but the MCP interrupt pin that I set (PA0) is already set as the BUT1 pin (on board button). I didn't change the configurations, only set in the callback to activate if occurs the rising edge of BUT1_Pin (tried with falling edge too).
It didn't work, but I don't know if I have to configure something more, or the fact that the pin is shared with the button changes something and it could be the problem.
Any insights will be helpfull.
