编写0号中断处理程序，使得在除法溢出发生时，在屏幕中间显示字符串“divide error!”，然后返回DOS。(Write 0 interrupt handler, so that when the division overflow occurs in the middle of the screen displays the string divide error! , And then return to DOS.)

This program draws an array of spheres lit by a spotlight whose cone angle can be changed and which can be moved as well. The spotlight cone is shown by a wireframe. The spheres are colored using color material mode.

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.)

STM32F407定时器实验，使用定时器控制LED闪烁，并且与while循环的闪烁灯进行时间的对比。(STM32F407 timer experiment uses timer to control LED flicker, and compares the time with that of the while cycle flicker lamp.)

The HIH-3610 Series humidity sensor is designed specifically for high volume OEM (Original Equipment Manufacturer) users. Direct input to a controller or other device is made possible by this sensor’s linear voltage output. With a typical current draw of only 200 mA, the HIH-3610 Series is ideally suited for low drain, battery operated systems. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. Individual sensor calibration data is available. The HIH-3610 Series delivers instrumentation-quality RH (Relative Humidity) sensing performance in a low cost, solderable SIP (Single In-line Package).
