这个代码是别人写的，为了测试USB的从机发数据到主机的数据，上位机和单片机的代码都有。...

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

温度和日晒是然后重新添加，液晶屏上显示。氙灯用于此目的。氙模拟器 （也人造太阳) 是提供近似自然光照明设备。太阳模拟器的目的是提供一个用于测试的太阳能电池、 太阳屏幕、 塑料，其他材料和设备的实验室条件下的可控的室内试验设施。氙灯是灯的最常见的为连续和闪太阳能模拟器。这些灯提供高强度和未过滤的光谱相匹配较好地在阳光下。然而，Xe 谱也具有许多不良原子过渡尖峰，制作的频谱不合意地对于某些光谱敏感的应用程序。氙弧灯可以被设计为低权力或提供的方法用于小或大面积照明和低到高强度的几个千瓦。
