// Modbus communication runs at 9600 baud Serial.begin(9600); // Modbus slave ID 2 node.begin(1, Serial); // Callbacks allow us to configure the RS485 transceiver correctly node.preTransmission(preTransmission); node.postTransmission(postTransmission); ...
Project: RS485 Serial Communication between two Arduino boards (Control LED Brightness) Let us demonstrate an example of RS485 serial data transfer between two Arduino boards using the MAX485 TTL to RS-485 module. Our aim will be to send ADC values from the master Arduino connected with a pot...
Simplicity, efficient communication, and streamlined and fast data communication make MODBUS RTU RS485 one of the most widely used serial communication protocols in electronics and instrumentation industries. Each device on the RS485 network is referenced by a unique 8-bit address or identifier. This ...

CSE_ArduinoRS485 This Arduino library allows you to send and receive data using the RS-485 interface standard. Supported by all Arduino-compatible boards such as ESP32, STM32, RP2040, AVR, SAMD, ESP8266, etc. You can use both hardware and software serial ports for communication. This libr...
This arduino library and C code serve for communication between arduinos and linux computer. Getting Started For arduino copy whole directory named RS485protocol to your libraries directory. For C use compilation command fromC compilation. Directories ...
RS485 converter which allows Arduino communicating with RS485 devices. The communication socket provides an extremely easy way to plug a wireless module such as APC220 RF module and DF-Bluetooth module. It has an individual power input for Servos. A servo power jumper allows user to select ...
