AT89S52+DS1302+1606具有可调的电子时钟-51 single-chip electronic clock experiment using ds1302+1602 LCD

本报告介绍了基于AT89S52单片机为核心的、以AD0809数模转换芯片采样、以1602液晶屏显示的具有电压测量功能的具有一定精度的数字电压表。在实现基础功能要求之上扩展了串口通讯、时钟功能、高压报警、短路测试、电阻测量、交流电压峰峰值和周期测试等功能，使系统达到了良好的设计效果和要求。- This report describes on AT89S52 microcontroller as the core, to AD0809 DAC chip sampling, digital vol

该方案通过AT89S52单片机读取实时时钟芯片DS1302和数字温度芯片DS18B20的内部数据，并进行处理后送到1602液晶显示来实现全部功能。-That clock mainly adopts the AT89S52 single-chip microcomputer as the main control core, provides clock through the DS1302 clock chip, collects and converts temperature through
