Modbus communication employs two distinct serial transmission modes: ASCII and RTU. Modbus ASCII (American Standard Code for Information Interchange) mode sends each 8-bit message as two ASCII characters. Advantages of ASCII mode include the ability to easily monitor messages on a text console.WARNING: This code is no longer being maintained and it's NOT compatible with Arduino IDE 1.x. We recommend you check out this improved version instead. Anyways, here you will find a rather old open-source version of Modbus RTU over serial line for the arduino microcontroller board. then you will have to look at the various libraries that may allow to implement modbus-rtu on an stm32 (or on an arduino, but there will obviously be more adaptations to do); anyway you will have to tailor them as you will have to use gpios to emulate the modem control signals of the usart (needed to drive the rs485 line drivers) that are not …RS485 Modbus-RTU 12V Relay Module Switch Controller for...
