说明： 串口通信是在工程应用中很常见。在上位机与下位机通讯过程中常通过有线的串口进行通信，在低速传输模式下串口通信得到广泛使用。在说个之前先来简单解释一下上位机与下位机的概念。
上位机与下位机
通常上位机指的是PC，下位机指的是单片机或者带微处理器的系统。下位机一般是将模拟信号经过AD采集将模拟量转换为数字量，下位机再经过数字信号处理以后将数字信号通过串口发送到上位机，相反上位机可以给下位机发送一些指令或者信息。常见的通信串口包括RS232、RS485、RS422等。这些串口只是在电平特性有所不同，在上位机与下位机进行数据通信时可以不考虑电平特性，而且现在在硬件上有各种转接接口，使用起来也很方便。
(Usually the upper computer refers to the PC, and the lower computer refers to the single-chip microcomputer or system with microprocessor. The lower computer generally converts the analog signal into digital value through AD acquisition. After the digital signal processing, the lower computer sends the digital signal to the upper computer through the serial port. On the contrary, the upper computer can send some instructions or information to the lower computer. The common communication serial ports include RS232, RS485, RS422, etc. These serial ports are only different in the level characteristics, the upper computer and the lower computer data communication can not consider the level characteristics, and now there are a variety of hardware interface, it is easy to use.)
