本程序为实验板的总体测试程序，综合测试了整个实验板上的绝大多数功能,下载程序后会依次看到以下5种状态。

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

3.接着前三位数码管显示温度值

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-This procedure for the experiment board' s overall test program, a comprehensive test of the vast majority of the entire experiment on-board features, download the program will in turn see the following five kinds of states. 1.8 water lights will first flow from top to bottom again, at the same time buzzer sound. 2. And then DAC current indicator light changes from the dark 3. And then the top three LED display temperature 4. And then AD values displayed in the top three digital tube 5. And then wait for the keyboard matrix is pressed, press the corresponding post- digital display in the digital control on the latter three
