说明：  简单的lcd1602显示代码，说明通俗易懂(Simple lcd1602 display code)

IEEE14节点模型，PSCAD案例，同步发电机功率60MW，电压等级230kV(IEEE14 node model, PSCAD case, synchronous generator power 60MW, the voltage level of 230kV)

plc 的电梯控制程序，含有组态软件,控制算法。plc 采用三菱fx1n(plc elevator control program, containing configuration software)

用普通遥控器做的电脑鼠标，遥控器发送数据，51单片机解码，通过串口发送到上位机上，在上位机上运行程序，实现鼠标控制(Do with an ordinary remote control computer mouse, the remote control to send data, 51 single-chip decoder, sent through the serial port to the PC, run the program on the host computer, mouse control)

超声波测距，在51单片机内核下的超声波测距程序，比较精简，希望大家受用。(Ultrasonic ranging, in 51 single kernel of ultrasonic distance measurement procedures, more streamlining, I hope everyone is good enough.)

lax-wendroff求前台阶超声速流动(lax-wendroff format)

定时器：设定时间格式（00：:00）后，到时间弹出提示(timer：set time(00:00),then run up)

超声波测距，测量精度为1cm，可以使机器人安全避障。(Ultrasonic distance measurement accuracy of 1cm, can make the robot obstacle avoidance safety.)

AD9851驱动程序，采用串行写入方式，STM32写入频率控制字。(AD9851 driver, using serial write mode, STM32 write frequency control word.)

数码管的显示程序，数码管循环显示900-999~(Digital loop display 900-999 ~)
