The Two-Wire Automotive Interface (TWAI) is a real-time serial communication protocol suited for automotive and industrial applications. It is compatible with ISO11898-1 Classical frames, thus can support Standard Frame Format (11-bit ID) and Extended Frame Format (29-bit ID). The ESP32’s peripherals contains a TWAI controller that can be configured to communicate on a TWAI bus via an external transceiver.

The TWAI controller is not compatible with ISO11898-1 FD Format frames, and will interpret such frames as errors.
