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。
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 temperature 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 simplifies the hardware design. As for the software design, main sub-programs, such as keyboard scanning, temperature measuring and timing, are all triggered by system interrupts. Therefore, it reduces system response time and improved working efficiency.
