由于 RS-232 是一个串行接口,我们可以将其用于 Modbus RTU 和 Modbus ASCII。 RS-485– 与 RS-232 相比,RS-485 具有更高的速度、更长的电缆,并且信号更强大。基于 RS-485 的 Modbus 可能是部署 Modbus 协议的最流行方式。我们可以使用 Modbus RTU 或 Modbus ASCII。 以太网– 在大容量数据传输方面,以太网...
This example uses two MODBUS RS485 Server Write blocks to implement the write operation on the input register and the discrete input register, respectively. To perform the 16-bit server write operation on the input registers, this example uses a counter that counts values from 0 to 255. The ...
Those of us here at Digilent don't have any experience with that particular RS485 chip or that library they are using. We have our own Pmod RS485 with an example code loopback code in itsResource Center, which will likely be a good thing to try to do with your particular chip. ...
最近在搞一个小东西需要用到直流无刷电机,用了一个比较高大上一点的控制器,带有多种控制功能;其中有个RS485总线控制的,通过读写寄存器来实现速度、加减速、制动、换向的控制。平常用的单片机是Arduino,没有485的接口,因此从网上买了TTL-->485的转换模块,现在这个模块做的很好了,都是流向自动控制,不用操心,用起...

由于创新实验室的项目中需要用到ArduinoModbus库。然而它又依赖与ArduinoRS485库。但是我们工程中只需要rs232通讯就可以了。因而我在这里fork ArduinoRS485代码 并修改为普通 硬件串口适用库。名字暂时还是不改了。
Modbus Library for Arduino UseModbuswith your Arduino. Using TCP or RS485 shields, like the MKR 485 Shield. This library depends on the ArduinoRS485 library. This library is based onlibmodbus, modifications were made to the lower level RS485 and TCP layers to use Arduino Serial/RS485 and ...
