Modbus-RTU (Remote Terminal Unit) meansthat the Modbus protocol is used on top of a serial line with an RS-232, RS-485 or similar physical interface. It is point to point communication which means it has only one master and slave. Modbus RTU is using binary coding and CRC error checking...
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...
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...
I am a beginner. I am trying to communicate (read values) with a device and the modbus address is ranging from 40200 to 40380. I am using max 485 ic to convert rtu to ttl. But on the serial monitor it is showing some garbage value. Is something missing i
