资 源 简 介
(1) 使用DS18B20制作一个数字温度计，使用数码管交替显示当前温度值和设定温度值；
(2) 使用键盘设定某一温度，通过DAC0832输出电压供给发热电阻RT1，使发热电阻RT1固定在该温度。-(1) Use a digital thermometer DS18B20 make use of digital tube alternately displays the current temperature and set temperature (2) use the keyboard to set a certain temperature, the supply of heat through the DAC0832 output voltage resistors RT1, so that heat resistance RT1 fixed in this temperature.
