STM32 Modbus RTU Full Course (HAL + RS485) | Master & Slave Complete Tutorial

Build a complete Modbus RTU communication system using STM32 and HAL in this full course.

In this 1 hour 45 minute tutorial, you’ll learn how to implement both Modbus Master and Slave using RS485, starting from basic UART communication to handling all major function codes like reading/writing registers and coils.
