万年历单片机课程设计报告

1、课程设计报告1任务和设计要求首先要学会安装软件，要熟悉会使用。基于AT89S52单片机的电子万年历枭用高精度12MHz晶振，满足如下技术指标工 (1)同时显示阳历年、月、日.星期、时、分、秒和阴历月、日0(2)具有较高的精确度，一年的误差为1s以下“ (3具有时间校准等功能.2系统设计系统框图按照系统设计的要求和功能,将系统分为主控模块，按键扫描模块、LED显示模块、电 源电路，复位电路、晶振电路、驱动电路几个模块，系统框图如图71所示。主控模块果用 AT89S52单片机,按铺模块只用了两个按键,用于调整时间，显示模块采用七段共阳LED 数码管.图7-1基于AT89S52单片机的电子万年历系统
