Important
For the CAN library to work correctly, the auto-generated HAL driver file needs to be patched.
Make sure to restore any changes made by the generator to the firmware/Drivers/STM32G4xx_HAL_Driver/Src/stm32g4xx_hal_fdcan.c file or the receiving won't work!
Below are the changes that need to be made to the stm32g4xx_hal_fdcan.c file:
