android上使用ZXing识别条形码和二维码，代码简单易懂，相信能帮助读者迅速掌握相关的开发(the use of android and two-dimensional bar code ZXing identification code, the code easy to understand, that can help readers quickly master the relevant development)

一种基于AT89S52单片机的光电开关转速测量系统的设计。系统采用反射式光电开关产生与齿轮相对应的脉冲信号，使用AT89S52单片机采样脉冲信号并计算每分钟内脉冲信号的数目，即电机对应的转速值，最终系统通过数码管实时显示电机的转速值(A photoelectric switch based on AT89S52 Microcontroller speed measurement system design. The system uses a reflective photoelectric switch with the gear corresponding to the pulse signal, the microcontroller AT89S52 sampling pulse signal and calculate the number of pulse signals per minute, the motor speed value corresponding to the final system in real time by digital tube display the value of the motor speed)
