G474 How to enable FDCAN error callback?

[Semer CHERNI]

Hello @wang_mo_mo 

First let me thank you for posting.

To activate the error callback you activate the FDCAN interrupt and it will generate a call to the interrupt service routine which will process all the interrupt sources including the errors.

Then you overwrite the callback function with the wanted behavior:

__weak void HAL_FDCAN_ErrorStatusCallback(FDCAN_HandleTypeDef *hfdcan, uint32_t ErrorStatusITs)

KR,
