How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source code has gone? Having the binary image and the source code as separate things ...

Abstract: This paper presents the design and implementation of a multipurpose networked control system using Arduino and Modbus RTU over RS-485 communication. The system enables robust and scalable ...

A generic firmware for an ESP32 to be used as a Modbus TCP/IP gateway for any modbus RTU device. Default RX/TX pins for the TTL-RS485 communication are used from hardware-serial2 (check pinout of your ...
