串口驱动配置流程及电路图设计
1、串口通信简介 串口通信指串口按位（bit）发送和接收字节，串口通信的概念非常简单，串口按位（bit）发送和接收字节。尽管比按字节（byte）的并行通信慢，但是串口可以在使用一根线发送数据的同时用另一根线 接收数据。它很简单并且能够实现远距离通信。比如IEEE488定义并行通行状态时，规定设备线总长不得超过20米，并且任意两个设备间的长度不得超过2 米；而对于串口而言，长度可达1200米。 串口

基于CPLD的RS-232串口通信实现
CPLD（Complex Programable Logic Device）是一种复杂的用户可编程逻辑器件。采用连续连接结构，延时可预测，从而使电路仿真更加准确。CPLD是标准的大规模集成电路产品，可用于各种数字逻辑系统的设计。开发工具Quartus II、ISE等功能强大，编程语言灵活多样，使设计开发缩短了周期。 随着嵌入式的发展，对数据的传输和人机交互通信的要求越来越高。而串口通信因其
