5、tersand一、硬件部分1、AT89C51芯片基本功能:AT89C51是一种带4K字节闪烁可编程可擦除只读存储器(FPEROM—FalshProgrammableandErasableReadOnlyMemory)的低电压,高性能CMOS8位微处理器,俗称单片机。该器件采用ATMEL高密度非易失存储器制造技术制造,与工业标准的MCS-51指令集和输出管脚相兼容。由于将多功能8位CPU和闪烁存储器组合在单个芯片中,ATMEL的AT89C51是一种高效微控制器,为很多嵌入式控制系统提供了一种灵活性高且价廉的方案。与MCS-
6、51兼容,含有4K字节可编程闪烁存储器,128*8位内部RAM,32可编程I/O线,两个16位定时器/计数器,5个中断源,可编程串行通道,低功耗的闲置和掉电模式,片内振荡器和时钟电路。引脚图:引脚功能:1、VCC:供电电压GND:接地。2.P0、P1、P2、P3口。3.RST:复位输入。当振荡器复位器件时,要保持RST脚两个机器周期的高电平时间。4.otherstaffoftheCentre.Duringthewar,ZhuwastransferredbacktoJiangxi,andDirectorofthenewOf
