基于ARM2131实现的modbus从站程序设计，改可以实现简单部功能的modbus协议的实现。提供参考。-Based on the achievement ARM2131 the Modbus Slave program design, change can be achieved a simple function of the Modbus protocol to achieve. Provide a reference.

MODBUS协议实现一主机对多从机轮询的示例。在工装设计之前做了这么一个仿真示例，展示主机与从机之间应用简易的MODBUS 04命令进行轮询会话的过程。PROTEUS设计中有标示，程序中代码有注释，希望能对需要的朋友有所帮助。-MODBUS protocol of a host of many examples of polling from the machine. Done before the tooling design such a simulation example that sh

使用stm32实现modbus通讯协议，验证的内容比较简单 实现点灯-Using STM32 to realize Modbus communication protocol, to verify the content is relatively simple to achieve lighting
