测试新买stc51单片机的功能是否正常。1.8个流水灯先会从上到下流动一遍，同时蜂鸣器发声。
2.接着DAC电流指示灯由暗变亮(最下面的一个LED灯D12,是DAC电流指示灯）
3.接着前三位数码管显示温度(需要把温度DS18B20传感器插入到学习板上面才有显示）
4.接着AD数值显示在数码管的前三位
5.接着等待矩阵键盘的按下，按下后相应的数码显示在数码管的后三位上-Buy stc51 SCM test new functionality. 1.8 from top to bottom water will flow over the first light and the buzzer sound. 2. Then DAC current indicator lit by the dark (the bottom of an LED light D12, is the DAC current indicator) 3. And then the top three digital display temperature (DS18B20 temperature sensors need to be inserted into the study only shows the top plate ) 4. Then AD values shown in the top three digital 5. and then wait for matrix keyboard pressed, pressed the corresponding digital display in the digital control of three on the back
