STM32 CAN Communication Explained | Send & Receive Data Between Two Microcontrollers

Learn how to implement **CAN protocol communication between two STM32 boards** (Blue Pill and Nucleo F446RE) step by step. This is **Part 2 of the STM32 CAN tutorial**, where we go beyond the basics and actually set up real hardware communication using **MCP2551 CAN transceivers**.

This tutorial helps you understand **STM32 CAN bus communication** in practice and is ideal if you are working on automotive, robotics, or embedded networking projects.
