说明：  用周立功的easyarm2200的板子，LPC2210的芯片，ucos系统 使用P0.25作为温度采集管脚， DS18B20和上拉电阻使用同一个+5V电源 LCD同时显示时间 和CPU使用率
(ZLG the easyarm2200 with the board, LPC2210 chip, ucos as the temperature acquisition system uses the P0.25 pin, DS18B20 and pull-up resistor to use the same+5 V power supply LCD also shows the time and CPU usage)
