Can driver usage.

Hi,

Have anyone used can driver on esp32 board. Is this reliable? any performance measurement will be appreciated.


Thanks,

I have tested 8000 frames per second with no errors once the driver is optimised (otherwise you get multi millisecond delays on receive and lost frames on sending). It still manages that with multiple other tasks and CPU speed reduced to 80MHz.

Have you tested using this latest can driver.

I am reading can frame using task/thread every 10 ms. I am losing frames time to time. it cannot cope high traffic on can bus.
