Description: 此程序是RS485从机通讯，包含3部分：接收帧程序、发送帧程序及执行命令程序。
从机通讯地址从地址开关读取4位
由于485的通信规约差别很大，这里只是提供参考，具体请参照自己的项目特点做修改,抛砖引玉。

Description: RS-485接口具有较强的抗干扰性，数据传输的距离较远，在一些应用中常常需要把RS-232标准的信号转换为RS-485的标准信号进传输。图中所示电路允许数据在RS-232/RS-485这两个不兼容的串行数据接口间传递。传输速度为480波特时，传输距离可达1750米。图中双RS-232收发器IC1将主机(PC)输出的RS-232电平转换为TTL电平，驱动高速RS-485收发器IC2 的输入，倒相器使IC2、IC3在受到起始位时被激活。-RS-485 trying to lay all the thoroughly bleed at the nose picking up the birthday 扰 fern cavity 强 ， Chu Huai basin cavity beat escapement for the birthday candle远Now ， Which instance, using Beckmannia中

Description: 利用SPCE061A，RS485 多路数据采集系统
本系统采用双CPU控制，主机与从机的CPU都是使用SPCE061A单片机。从CPU负责采集七路数据，同时应答主CPU发送的命令。主CPU进行数据处理，数据显示，键盘输入，系统报警，语音播报通道的电压值。在主CPU与从CPU的通讯中，采用国际标准的RS485差分方式接口，使通讯的速率和传输距离均大于RS232的标准接口方式，并且用线最少（只要两根）。本系统实现了一种具有语音播报、语音提示的高性能、高智能的实用型远距离多路数据采集系统。-The use of SPCE061A, RS485 multi-channel data acquisition system using dual-CPU of the system control, the host machine s CPU from SPCE061A Singlechip use. From the CPU is responsible for collecting data on seven routes, while answering the main CPU to send commands. The main CPU for data processing, data display, keyboard input, the system alarm, voice broadcast channel voltage. In the main CPU and the communications from the CPU, using international standards, the way RS485 differential interface to enable communication rate and transmission distance were greater than the standard RS232 interface mode, and with lines at least (as long as 2). The system achieved a voice broadcast, voice prompts, high-performance, high intelligence, practical long-range multi-channel data acquisition system.
