基于超低功耗单片机的RTC时钟的设计实现

Design of RTC clock based on microcontroller

超低功耗仪器能够在电池供电情况下,工作较长时间。基于德州仪器的MSP430F5529单片机开发的实时时钟,兼顾了超低功耗性能,同时为实时系统的开发提供了一个廉价实用的控制器。该实时时钟集模拟时钟显示、数字时钟显示、背光度调节、时间设置和闹钟设置的功能于一体,充分利用了MSP430F5529单片机的诸多优良性能:低功耗、外部按键中断能力、高效的AD转换能力、本身所固有的RTC_A(实时时钟)模块和闹钟模块等等。总的来说文中基于单片机的实时时钟设计能够很好将模拟技术和数字技术结合,在人工智能方面采用键盘、声音相结合,极大地丰富了应用价值。

The instrument ol ultra-low power consumption can work longer hours under the circumstanceol battery-powered. The development ol the real-time clock based on TI ’ s M S P 430F5529,takes intoaccount the ultra-low-power performance,while providing a cheap and practical controller lor thedevelopment ol real-time systems. The lunction ol the real-time clock includes the display ol analogclock,the display of digital clock,backlight adjustment,the setting of time and the setting of alarm. A n d itmakes lull use of the excellent properties of the M S P 430F5529 ：low power consumption,external buttonsinterrupt capability,and efficient A D conversion capability,inherent R T C _ A （ real-time clock） module,and so the alarm module. Generally,the design of the real-time clock can combined analog technologywith digital technology well. In artificial intelligence, the use of the keyboard and sound could greatlyenrich the application value.
