使用读卡器实现了为个人化的IC卡数据读写(Achieved using the reader for personal IC card data read and write)

S1D13700很好的驱动程序,功能全，基本涵盖了S1D13700所有的功能(S1D13700 a good driver, full-featured, covering all of the features S1D13700)

白噪声发生器，利用白噪声发生器产生白噪声。白噪声发生器，可以调制幅值，频率，相位。白噪声发生器，是一款很好的发生器。(White noise generator, the use of white noise generator white noise. White noise generator, can be amplitude modulation, frequency, phase. White noise generator, is a very good generator.)

使用IIC实现24C08读写驱动程序，并用数码管显示读写值(To read and write using the IIC to achieve 24C08 driver, and used digital tube display to read and write the value of)

说明：  dht11封装库，直接就可以用简单方便快捷。(DHT11 package library is simple, convenient and quick to use.)

51单片机开发板LED流水灯 有C和汇编两版 直接可以打开(51 single LED lights have two editions of C and assembler)

基于STM32F103的西门子S7-200系列PPI通讯开发参考(Reference for development of SIEMENS S7-200 series PPI communication based on STM32F103)

采用51系列单片机为控制核心，包括电源变换处理及分配模块，恒流源模块，单片机主控模块，键盘输入模块，LCD显示模块，数模/模数转换模块，语音模块和实时时钟模块的9个部分。通过键盘设定好需要输出的电流值后，单片机对设定值按照一定的算法进行处理，经数模输出电压控制恒流源电路输出相应的电流值(51 Series single-chip microcomputer used for the control of the core, including the processing and distribution of power transform module, constant current source module, single-chip control module, the keyboard input module, LCD display module, digital-to-analog/analog-digital conversion module, voice module and real-time Clock Module Part 9. Through the keyboard need to set output current value, single-chip microcomputer according to the settings of the algorithm processing, digital-to-analog output voltage by the control constant current source circuit output current value of the corresponding)

pat advanced level 1005. Spell It Right(Given a non-negative integer N, your task is to compute the sum of all the digits of N, and output every digit of the sum in English. Input Specification: Each input file contains one test case. Each case occupies one line which contains an N (<= 10100). Output Specification: For each test case, output in one line the digits of the sum in English words. There must be one space between two consecutive words, but no extra space at the end of a line. Sample Input: 12345 Sample Output: one five)
