Wanting to control a split flap display that was not near a computer [Tom] looked to a common solution for communicating over distances not practical for I2C or SPI. He developed his own hardware and ...

RS485 is an experimental library to make half duplex communication easier. The library implements the Stream interface so the user can use print() and write() calls just like one does with Serial.

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 ...

RS485是工业控制场景下，应用得非常广泛的通信协议，RS485的差分物理信号在电磁环境复杂的工业现场，有强大的抗干扰能力。 对于平时专注于应用软件开发的工程师，使用RS485进行数据传输，只要关注串口的数据收发器即可，但其实在硬件层面，RS485通信的数据 ...

Arduino UNO SPE Shield adds Single Pair Ethernet (SPE) and RS485 to Arduino UNO and compatible boards, notably the Arduino UNO R4, via a Microchip LAN8651 SPE controller. Single Pair Ethernet relies ...
