基于单片机的基于 12864 的万年历加温度显示设计

摘 要



本设计将制作一种基于单片机控制的带实时温度显示、 具有定时功能的电子 万年历。传统的电子日历大都体积大，功耗大，显示不准确等特点。为了缩小体 积，减小功耗，使其变得小巧灵敏，本设计加入了时钟芯片 DS1302，可对时间 进行准确记时，同时可设置定时时间，实现定时功能。-This design creates an electronic calendar with real-time temperature display and timing function based on single chip control. Most of traditional calendars are characterized by large size, high power consumption and inaccurate display.In order to reduce volume and power consumption and make calendars become small and exquisite, the design adds a clock chip DS1302, which can accurately record the time and set a regular time to achieve timing function. In addition, this design displays real-time temperature function. Traditional temperature sensor system is mostly amplified, recuperated and A/D converted. The converted digital signal is input the computer to be processed, but the processing circuit is complicated with relatively poor reliability and occupies more resources of the computer.
