RS-485是一种异步串行通信协议，不需要时钟。它使用称为差分信号的技术将二进制数据从一个设备传输到另...
RS-485模块可以连接到任何带有串行端口的微控制器。微控制器使用RS-485模块时,需要一个基于Maxim MAX485的5V MAX485 TTL到RS485的模块,因为它允许1200米长距离的串行通信。它是双向和半双工的,数据传输速率为2.5 Mbps。该模块需要5V的电压。 RS-485模块的引脚输出定义: USB转RS-485转换模块: 这是一个USB转RS485...
ArduinoRS485 Library for Arduino Enables sending and receiving data using the RS-485 standard with RS-485 shields, like the MKR 485 Shield. This library supports the Maxim Integrated MAX3157 and equivalent chipsets. For more information about this library please visit us athttp://www.arduino.cc...
This library is a fork of the ArduinoRS485 library by Arduino, and is maintained by CIRCUITSTATE Electronics. Installation This library is available from the official Arduino Library Manager. Open the Arduino IDE, search for CSE_ArduinoRS485 and install the latest version of the library. Addition...
Arduino Modbus 协议库这个库是为了让你的arduino之间通过MODBUS协议进行通讯。Modbus是一种用在工业自动化的主从协议,也可以用在别的地方,比如智能家居。 Modbus一般使用 rs-232 或者rs-485 协议作为物理层(也叫modbus串口),modbus 通过以太网或者WiFi (也叫Modbus IP)使用 TCP/IP 。 最新的版本库允许arduino...

RS485 Module with Arduino UNO (Slave) Installing OLED Libraries in Arduino IDE To use the OLED display in our project, we have to install the Adafruit SSD 1306 library and Adafruit GFX library in Arduino IDE. Follow the steps below to successfully install them. ...
RS485 is used to send data and receive serial data. If more than two devices connected serially then we can communicate devices with one another. To connect more than two devices on the same line and have a distance greater than 50 feet than we will use RS485 or RS422. RS485 can trav...
