Has anyone got any? Both under interrupt and polled?

All I can find are trivial examples that don't look for or handle errors

#stm32 #can

Hi bigden.gary,

What examples did you checked?

Depending on the product you use, you may find some examples on its STM32Cube FW package.

Ex: STM32Cube_FW_F4_V1.11.0\Projects\STM324xG_EVAL\Examples\CAN.

No, I think he's looking for something a little more involved.

As far as I can tell, I am doing everything right using the STM Peripheral Library when it comes to using CAN. However, unless I put ''magic number delay'' into the transmit status testing I am overwriting the Tx buffer and losing packets. I posted my code in a previous thread.

Well, i guess that nobody would send you his handler or code of the can bus handling. In most cases that this is a secret of the developer.
