1、摘要摘要本文介绍了基于AT89S52单片机的多功能电子万年历的硬件结构和软硬件设计方法。本设计由数据显示模块、温度采集模块、时间处理模块和调整设置模块四个模块组成。系统以AT89S52单片机为控制器,以串行时钟日历芯片DS1302记录日历和时间,它可以对年、月、日、时、分、秒进行计时,还具有闰年补偿等多种功能。温度采集选用DS18B20芯片,万年历采用直观的数字显示,数据显示采用1602A液晶显示模块,可以在LCD上同时显示年、月、日、周日、时、分、秒,还具有时间校准等功能。此万年历具有读取方便、显示直观、功能多样、电路简洁、成本低廉等诸多优点,具有广阔的市场前景。关键字:万年历温度计液晶
