实现RS485多机通信 AT89S51 keil通过-The realization of multi-machine communication RS485 through AT89S51 keil

我做的畢業設計,用AT89S51 控制LCD1602作為顯示. DS1302時鐘芯片顯示時間,DS18B20測量溫度,還有4X4的鍵盤驅動.實現了一個計算功能.可以用PROTUES 仿真軟件仿真,當時我還做出實物來了.-Designed to do my graduation with AT89S51 control as LCD1602 display. DS1302 display time clock chip, DS18B20 measurement of temperature, ha

用C语言编写的,在Keil下运行,用Proteus下仿真的AT89S51的IO口,中断,串并口实验代码及原理图.-Using C language, in Keil run, under the simulation with Proteus AT89S51 the IO ports, interrupts, serial and parallel test code and schematics.
