Hi,

I'm having issues compiling for stm32f405 via Arduino framework for stm32 via PlatformIO. Here are the errors I'm getting.

Hi, I fixed this by commenting #include in SimpleCAN.cpp in /src folder of your library. That's no longer try to found reference to HAL_CAN_IRQHandler and works great. Actually to fix this property you need some addiction libraries for your stm32. You will need to paste stm32fxxhall*.h to /lib/SimpleCAN-main/src or just comment include in main file. Good luck.

I'm going to close this issue. I've completely rewritten this library recently, and this issue is 2.5years old (with a workaround provided by flexbrionine)
