STM32F7 CAN Loopback Test

Overview

This project performs a loopback test on the CAN1 peripheral of an STM32F7 microcontroller (e.g., STM32F746G-DISCO board). It validates the send and receive paths using a single node and toggles an LED when transmission and reception succeed.

Features

  • STM32 HAL-based CAN implementation
  • Standard ID (0x123), 8-byte payload
  • Filter config to accept all messages
  • Loopback verification with LED feedback

Hardware Setup

  • LED connected to GPIOB Pin 0
  • STM32F7 board running at default clock config
  • CAN1 in loopback mode (set via CubeMX or manually)

How to Use

  1. Import this into STM32CubeIDE
  2. Ensure CAN1 is in loopback mode
  3. Flash to your board
  4. LED will toggle when message is received and validated
