通过反转法循环扫描矩阵键盘，并通过数码管显示数据(By inversion method cyclic scan matrix keyboard, and through the digital display data)

在飞思卡尔32位的单片机K60的平台上实现线性CCD采集图像的功能；能够实现自动曝光功能；很好的调节图像；(K60 implemented on Freescale MCU platform 32 linear CCD image acquisition functions able to achieve automatic exposure function well adjust the image )

智能安防报警系统是集布防,检测,报警为一体的软硬件相结合智能化系统。(Intelligent security alarm system is a deployment, detection, alarm as one of the intelligent combination of hardware and software systems.)

用整数存储私有成员：年、月和日。为类提供构造函数，能够对各成员进行初始 化，但出现错误的初值时, 成员为2000-1-。也可以不在不提供任何初值的情况 下日期为2000-1-1。另外可以用一个Date 对象进行初始化，成员函数应实现以 下功能： （1） 对所有成员一次性赋值，也能对某个成员单独赋值，能够一次返回所有成 员的值，也能单独返回某个成员的值 （2） 可以按照mm-dd-yyyy 格式输出日期。 （3） 有成员函数nextDay（），用于将日期增加一天(Integer stored the private Members: year, month, and day. Class provides a constructor to initialize the members, but the wrong initial value, members 2000-1-. The date can also be not the case does not provide any initial value 2000-1-1. Also available on a Date object is initialized, the member function should achieve the following functions: (1) all members of the one-time assignment, can also be a member of a separate assignment, to return once the value of all the members, but also separate return a The members of the value (2) according to the date of mm-dd-yyyy format output. (3) member function nextDay () for additional day date)

基于STM32的12864LCD显示屏的驱动程序，通过8080时序并口通信，可以直接调用函数编写，使用起来很方便(Based on the STM32 12864LCD display driver, by 8080 the timing parallel communication, you can directly call functions written, easy to use)

使用51单片机以及红外管，这段代码实现小车沿着黑色线路准确行走，但是要自己修改到合适的左右轮速度才能完美转弯。(By using 51 MCU and IR LED light tube, the code can achieve the goal of moving according to the black line. But you need revise the speed data of the left and right tire so that the car can turn aroud perfectly. )

at89c2051利用74ls164 驱动 共阳极数码管(74ls164 driver to use a total of at89c2051 digital tube anode)

此文件是arduino mega 2560单片机与Matlab结合的应用，可以通过matlab观察arduino的输出，程序有详细的注解，里面包含了一些实例。适合初学者学习。(This file is arduino mega 2560 microcontroller applications in conjunction with Matlab, arduino output can be observed through matlab, procedures detailed comments, which contains a number of examples. Suitable for beginners to learn.)

说明：  古老电子荧光管做的数字钟，可以调时间。整点闹钟。(Electronic fluorescent tubes to do the old digital clock, you can transfer time. The whole point of alarm.)
