| 摘 要： | PC机与外设的I／O通讯通常用并行I／O卡实现，成本较高。而通过RS232串行口与2051单片机通讯实现I／O控制，能使成本显著降低，且容易扩展。PC机端程序在VC 6．0下用MSComm控件实现，单片机端程序在Keil51下用C语言编写，数据传输以16进制进行。

| Abstract: | The parallel I/O card, which costs more,is normally used to communicate between PC and peripheral equipments.To reduce cost,I/O control is realized by RS232 serial communication between PC and MCU 2051 in this paper.The program on PC is completed by MSComm in VC++6.0,and the MCU's is written by C language in Keil51.The data is transferred in the hexadecimal format. |
