程序为温度报警系统，功能如下：
1. 显示当前时间和温度，时间显示采用实时时钟，掉电后时钟继续工作；
2. 可以通过外部键盘设置温度的上限值和下限值，温度超过上限值和下限值分别报警，并有声光指示；
3. 报警后记录当前温度和时间，并保存到EEPROM，每5分钟最多报警一次，报警记录要求能够查询；
Procedures for the temperature alarm system, functions as follows: 1. Displays the current time and temperature, time display real-time clock, the clock continues to operate after power 2 external keyboard can set the temperature of the upper limit and lower limit, the temperature exceeds the upper alarm limit and lower limit, respectively, and a sound and light indication 3 alarm record the current temperature and time, and saved to EEPROM, once every 5 minutes up to an alarm, the alarm recording requires the ability to query (2013-08-20, Asm, 7KB, 下载5次)
