S32K344 CAN AUTOSAR using Interrupt Mode - Example

MVR — Thu, 23 May 2024 04:09:14 GMT

Hello everyone,

I'm looking for any example about CAN using interrupt mode.

I created the code on Tresos tool and I'm using FreeRTOS as the OS.

My code always getting a bus off error. I would like to compare with any example, I was able to find only Polling mode examples.

Thanks

Hi,

I am not aware of such example.
However for bus off; it is entered when MCU is transmitting and detect bit error. This can be caused by wrong pin setting, or fault on transceiver, so check that.
