利用SPComm控件实现的PC机与单片机串口通讯

Using SPComm component to realize Serial Communication between PC and Single-chip

本文介绍一种基于Delphi语言利用SPComm控件实现PC机与单片机串口通讯的软硬件实现方法。给出硬件设计思路,介绍SPComm控件的使用发法。详细介绍PC机与单片机多机通讯的通讯原理,通讯协议以及软件实现方法。着重介绍上位机通讯软件实现过程中几个重点环节的解决发法。

This paper will introduce the method of using SP- Comm component to realize serial communications between PC and the single-chip. A hardware design will be provided. It also introduces how to use SPComm. Meanwhile, it will introduce the communication principle and protocol, providing the software design, discussing the solution to key problems in using SPComm to realize the serial communication seriously.
