STC89C52八位密码锁论文，包括制作资料和原理图/PCB/BOM,及C代码。可做成实物(STC89C52 eight locks papers, including the production of information and schematic/PCB/BOM, and C code. Can be made in kind)

基于PSCAD的双环两电平仿真电路，对于理解三电平原理非常有用。(Based on PSCAD bicyclic two-level circuit simulation, very useful for understanding the three-level principles.)

单片机完成两个功能：电机测速与频率测量，电机测速部分：单片机输出脉宽可调的方波控制电机速度，同时数码管显示电机的速度值。频率计部分：单片机完成对外部信号频率的测量，测量范围从2hz到10mhz，并通过数码管显示频率值。(MCU to complete two functions: motor speed and frequency measurement, the motor speed parts: the microcontroller output square wave pulse width adjustable motor speed control, digital display while the motor speed value. Frequency counter parts: MCU to complete the external signal frequency measurement, measuring range from 2hz to 10mhz, and through the digital display frequency.)
