次代码是针对STC8系列的单片机的延时函数，使用 此代码可以直接添加调用，程序自动获取内部系统时 钟后初始化延时函数。只要是ISP软件默认的时钟频 率都可以应用（特殊频率除外） 该代码为初版，还存在很多缺陷，请各位大佬勿喷，谢谢！ 注意： 次代码仅适用于STC公司最新的STC8系列单片机(Delay Function of Single Chip Microcomputer)

基于单片机的红外遥控系与测距系统，包括车载雷达测距等(Infrared remote control system based on SCM and ranging system)

Zedboard上板载有一个USB转UART串口，采用了Cypress公司的USB-UART控制器CY7C64225。Zedboard的USB驱动安装很简单，首先下载USB驱动程序，解压缩后会有3个子目录分别对应Windows XP、Windows Vista和Windows 7系统，根据自己的计算机系统选择。(Onboard there Zedboard a USB-to-UART serial port, using Cypress' s USB-UART controller CY7C64225. Zedboard USB driver installation is very simple, first download the USB driver, unzip have three subdirectories corresponding to Windows XP, Windows Vista and Windows 7 systems, according to their own computer systems to choose from.)

使用8脚单片机STC15F104E DS1307 DS18B20 以及LCD1602 红外接收头制作的迷你时钟，其中驱动1602只使用了两个IO口。遥控器芯片兼容HT6122，采用状态机方式完成解码。(Use 8-pin microcontroller STC15F104E DS1307 DS18B20 and LCD1602 produced mini infrared receiver clock, which drives 1602 using two IO ports. Remote control chip is compatible with HT6122, accomplished using the state machine decoder.)

步进电机28BYJ48型四相八拍电机，电压为DC5V—DC12V。当对步进电机施加一系列连续不断的控制脉冲时，它可以连续不断地转动。每一个脉冲信号对应步进电机的某一相或两相绕组的通电状态改变一次，也就对应转子转过一定的角度（一个步距角）。当通电状态的改变完成一个循环时，转子转过一个齿距。四相步进电机可以在不同的通电方式下运行，常见的通电方式有单（单相绕组通电）四拍（A-B-C-D-A。。。），双（双相绕组通电）四拍（AB-BC-CD-DA-AB-。。。），八拍（A-AB-B-BC-C-CD-D-DA-A。。。）(Stepping Motor 28BYJ48 four-phase eight-phase motor, the voltage DC5V-DC12V. When a series of continuous control pulses are applied to the stepper motor, it can be continuously rotated. Each pulse signal corresponds to the stepper motor of a phase or two-phase winding power state change once, also corresponds to the rotor through a certain angle (a step angle). When the change in the power-on state completes one cycle, the rotor turns one pitch. Four-phase stepper motors can be operated in different power-up modes. The common power-up modes are: single-phase winding power (ABCDA ...), double (dual-phase winding)-DA-AB-...), eight beats (A-AB-B-BC-C-CD-)
