| 摘 要： | 介绍了多功能数字钟的系统设计。系统具有时间设置及显示、闹钟、温度显示、遥控止闹等功能。系统以MSP430为核心,该单片机内部集成了温度传感器,极大地简化了硬件设计。因为MSP430内部中断资源丰富,键盘扫描、温度转换、定时等均采用中断触发,减少了系统响应时间,提高了软件执行效率。

| Abstract: | This paper describes the design of a multi- function digital clock system. It as displaying and setting time for clock and alarm, this system has other special features such as tem- perature measurement and data protection at power failure. Meanwhile, alarm clock can be shut down by remote control. The core part of the system is based on a kind of advanced MCU, MSP430. With temperature sensor embedded, MSP430 is a good choice for temperature measurement, which greatly sim- plifies the hardware design. As for the software design, main sub- programs, such as keyboard scanning, temperature measur- ing and timing, are all triggered by system interrupts. Therefore, it reduces system response time and improved working efficiency. |
