Two-Wire Automotive Interface (TWAI)

[中文]


What are the considerations when using the ESP32 TWAI® controller?

Please refer to the ESP32 Series SoC Errata > Section ESP32 TWAI Errata.


Does ESP32-S3 support CAN-FD?

The ESP32-S3 itself does not integrate a CAN-FD controller, but users can still use a CAN-FD controller with an SPI interface, such as the MCP2518FD.


Does ESP32 support interrupt mode for CAN reception?

The TAWI driver already uses interrupt reception, and automatically stores the received information into the RX queue.
