基于AT90S8535单片机的电子万年历挂钟系统设计

设计中选用高性能低功耗的AVR架构单片机AT90S8535作为系统的控制核心,并采用高集成度的实时时钟芯片SD2303和DS1722温度传感器来处理时间和温度检测任务,能实现实时时间和温度的检测和显示。AT90S8535单片机带有SPI接口,能非常便利地实现和DS1722的通信。在设置闹铃时,程序会对所设置时间的合理性进行检测,任何不合理的时间设置将关闭闹铃功能。

AT90S8535 microcontroller based on the electronic calendar clock system design

Design of high performance and low power consumption AVR architecture AT90S8535 MCU as the core of the control system, and the use of high integrated degree, real-time clock chip SD2303 and DS1722 temperature sensor to the processing time and temperature detection task, can realize the real time and the temperature detection and display.AT90S8535 microcontroller with SPI interface, can be very convenient to achieve and DS1722 communication.In the setting of an alarm when a program on the setting time, the rationality of the inspection, any unreasonable time setting off the alarm function.
