程序采用枚举法,顺序获取u-disk设备描述符(包括vid、pid...)-Procedures using enumeration method, the order to obtain u-disk device descriptor (including vid, pid ...)

基于stc89c52实现具有校时模式、定时模式，能够显示月、日、星期等功能的电子钟。-When the realization of the school-based stc89c52 mode, timing mode, can display month, day, week, and other functions of the electronic clock.

用单片机实现E1等芯片的初始化，给出了E1芯片DS21Q53的初始化方法-E1 MCU chip initialization, given the DS21Q53 E1 chip initialization method

TS12864液晶驱动，max7219数码管驱动，键盘串行驱动，C8051F120芯片ADC和DAC驱动，可定位任意长度和宽度的FIFO源。实现了单级触发、三级触发、起始触发、终端触发、三级触发等功能。在示波器中，XY模式显示清晰的8通道逻辑信号

ICDLL1. AT24C01A/02/04/08/16/64卡 该系列IC卡均为非加密存储卡，容量分别为1K，2K，4K，8K，16K，64K bit，只有读、写两种操作。-ICDLL 1. AT24C01A/02/04/08/16/64卡 该系列IC卡均为非加密存储卡，容量分别为1K，2K，4K，8K，16K，64K bit，只有读、写两种操作。

程序描述：这个范例说明如何使用8051，以及汇编语言的程序连结， 当我们按下向上数的按钮之后，程序就会把0到9的共 阳7段显示器字型码存入AT93C46；如果我们按下向下 数的按钮之后，程序就会把9到0的共阳7段显示器字 型码存入AT93C46。 程序每一次重新开始执行时(Power on 或是Reset)，8051 会先从AT93C46当中读出最前面的10个位组，然后 就反复地将这10个位组的数据经由PORT 1送到1个 共阳七段显示器。*/-Procedure Description: This example shows how to use the 8051, as well as links to assembly language programs, when we pressed up a few of the button, the program will bring a total of 0-9 yang seven segment display font yards into AT93C46 if we press Next down the number button, the program will bring a total of 9-0 Yang seven segment display font code into AT93C46. Process to begin again each time when the (Power on or Reset), 8051 will start with AT93C46 were read out in front, 10-bit groups, and then repeated these 10-bit groups of data via the PORT 1 sent to a A total of seven-segment display Yang.* /

提供信号发生芯片AD9833的使用实例。包括命令字的初始化以及一个通用波形发生函数。-provide signal generation chip AD9833 examples of the use. Including the order of the words and initialize a common occurrence waveform function.

本程序的功能是在51单片机上实现51tiny嵌入式操作系统编程-this program is to tell how to use 51tiny embedded system to program

设计的主要内容如下 （1）设计一款电子秤，用LED液晶显示器显示被称物体的质量 （2）可以设定该秤所称的上限 （3）当物体超重时，能自动报警 （4）写出详细的实验报告 -The design of the main contents are as follows (1) the design of an electronic scale, liquid crystal display with LED shows that the quality of objects (2) can set the scale referred to as the upper limit (3) When the objects are overweight, they can auto-alarm (4) write a detailed experimental report

这是用单片机实现的多功能数字钟,通过8255扩展端口,AD0809将模拟信号转换成数字信号进行处理,可以比较精确的测出电压值.-This is the MCU multifunction digital clock, through the 8255 expansion port, AD0809 a conversion of analog signals into digital signal processing, more precise measuring the voltage values.
