HAL_CAN_ERROR_PARAM in CAN BUS in STM32-L432KC

Javier Parra · ‎2023-02-20

Hello

I'm trying to communicate two L432KC between them by CAN Bus, but I can't because it seems that the mailboxes are full and the HAL_CAN_ERROR_PARAM stops the program. How can I fix it?

Thank you very much

That type of communication can be done. Hard to tell why it didn't work for you without seeing code.

I solved it

It seems that i didn´t clear the buffer reading it, so it failed because the mailboxes were full.

If anyone wants to see the code tell me and I upload it.

Thank you very much
