简易谐波分析仪
采用12位MAX 197对外部信号采样。采用全周波傅立叶积分算法，对采样信号进行处理，对电力系统的电压有效值、功率等特征量进行实时在线监测；采用全数字测量法测量相位差；并采用自适应技术调整采样间隔，消除非同步采样对计算造成的误差，利用PIC18F458捕获功能实时监测电力系统频率波动，修订采样间隔。分析了各量的测量误差，均达到标准。并提供友好的人机交互界面。(used 12 MAX 197 pairs external signal sampling. Using Fourier-Cycle Integration Algorithm for the sampling signal processing, power systems to the RMS voltage, power characteristics of the volume in real-time on-line monitoring; All digital measuring method phase difference; Adaptive technology and the sampling interval, the elimination of non-synchronous sampling of the calculation error using PIC18F458 capture real-time monitoring of power system frequency fluctuations amended sampling interval. The analysis of the measurement error are up to standard. And to provide a friendly man-machine interface.)

USB读卡器(Slave)实验
说明： 本实验将实现如下功能：开机的时候先检测SD卡和SPI FLASH是否存在，如果存在则获取其容量，并显示在LCD上面（如果不存在，则报错）。之后开始USB配置，在配置成功之后就可以在电脑上发现两个可移动磁盘。我们用DS1来指示USB正在读写，并在液晶上显示出来，同样，我们还是用DS0来指示程序正在运行。(This experiment will achieve the following functions: when booting, first detect the existence of SD card and SPI FLASH, and if there is, obtain its capacity, and display it on the LCD (if not, report an error). Then the USB configuration is started, and after the configuration is successful, two removable disks can be found on the computer. We use DS1 to indicate that the USB is reading and writing, and display it on the LCD. Similarly, we use DS0 to indicate that the program is running.)
