code

说明：  用mcs-52系列单片机实现等精度频率测量，T1引脚接被测TTL信号，晶振22.1184MHz，对任何频率都可以实现很高精度的测量（精度<1 )，结果从串口字符串输出，波特率115200，可以用串口调试器观察结果.(With mcs-52 family of single chip and other precision frequency measurement, T1 pin then measured TTL signal, Crystal 22.1184MHz, any frequency can be achieved very high accuracy of measurement (precision<1 ), the result string from the serial output , baud rate 115200, serial debugger can observe the results.)

这个是我自己编写的，小车程序，通过H桥控制电机运转，实现小车的行走功能，已经激光判断，循迹，判别路口转弯(This is what I have written, car program, controlled by H-bridge motor running, walking function to achieve the car has a laser judgment, tracking, discrimination intersection turn)

以前电子竞赛时写的M3 ARM控制TFT液晶显示正弦波波形可以连贯的左移，没有闪烁感，我还写了一个也是正弦波左移，只不过有一点闪烁，我也上传了，你们需要可以找一下！(Writing contest before the electronic control M3 ARM TFT LCD sinusoidal waveforms can be coherent left, no flashes, I also wrote a sine wave is left, just a little flicker, I also uploaded, you need to be able to Get it!)
