Esp32 Canbus Shield

The id3esp32odb2 is an ESP32 based DIY OBD2 Bluetooth dongle and an Android app to show diagnostics data from a VW ID.3 car on an Android device.

This repository contains code for testing CAN bus communication on STM32 Nucleo-F446RE boards using MCP2515 and SN65HVD230 transceivers. It implements continuous multichannel ADC sampling via DMA, CAN message transmission between boards, and serial monitoring of CAN traffic and sensor data.
