Arduino TWAI library for Xiaomi CyberGear

A simple Arduino project to show how to communicate with your car's OBD2 port using an ESP32-C3 and SN65HVD230 CAN bus transceiver, using ESP32 TWAI (Two-Wire Automotive Interface)

This Arduino IDE based project showcases how the ESP32 TWAI (Two-Wire Automobile Interface, concept conceived by Espressif, implements the CAN Bus) sends and receives normal, loopback, RTR CAN Bus messages.

🔌Reliable lightweight CanBus library with built-in watchdog aiming to support integrated CAN driver inside ESP32 microcontroller dedicated to devices operating 24/7.

ESP32-based real time WiFi-to-CAN transparent bridge with LAWICEL/SLCAN protocol support. Extends CAN bus wirelessly via UDP or USB wired serial.

A smart home system based on the CAN/TWAI interface. The ESP32-C6 chip was selected as the network device controller. Система "Умный дом" основанная на интерфейсе CAN/TWAI. В качестве контроллера устройств сети выбрана микросхема ESP32-C6.
