Just a heads up for anyone that uses the TWAI interface.

With the esp-idf 5.5.1 the old TWAI API has been deprecated and replaced with a new API.
Hopefully the same problems that have occurred (and still seem to be unresolved) with the i2c interface won´t appear. So far so good..

The old API still works (for now I guess) but in the Espressif documentation there are lots of bugs in the code samples.

The example in the esp-idf tree are correct and do compile (https://github.com/espressif/esp-idf/blob/master/examples/peripherals/twai/twai_network)

Hope this helps someone.
