用4BIT OTP单片机实现USB/PS2 MOUSE的设计 USB 低速设备的设计发展到现在已经有了相当的成熟度。 各家IC公司都推出了USB DEVICE端的解决方案, 一般以8 BIT CPU CORE + USB SIE为主流构架。 SH69P04是中颖电子(Sinowealth)本着丰富USB产品应用,降低USB IC成本而设计的4BIT OTP单片机, 用以开发USB DEVICE设备。-the design of usb or PS2 mouse

This circuit automatically turns on a night lamp when bedroom light is switched off. The lamp remains ‘on’ until the light sensor senses daylight in the morning. A super-bright white LED is used as the night lamp. It gives bright and cool light in the room. When the sensor detects the daylight in the morning, a melodious morning alarm sounds. The

内附IC读卡器设计方案,该设计使用89C52和MCM200,里面有详细的设计过程及程序代码,相信有一定IC卡经验，技术及具有一定的计算机软/硬件技术（尤其是微处理单片机MCU技术）的同行定能将本文消化之后而能设计出诸多应用场合的产品.-containing IC reader design program, which is designed to be used 89C52 and MCM200. There are detailed design process and procedure code, I believe a certain IC card experience, Technology and certain computer software/hardware technology (especially microprocessor MCU MCU technology) counterparts can extend the after the text digest able to design many applications products.

常用的说话人识别方法有模板匹配法、统计建模法、联接主义法(即人工神经网络实现)。考虑到数据量、实时性以及识别率的问题，采用基于矢量量化和隐马尔可夫模型(HMM)相结合的方法。 　　说话人识别的系统主要由语音特征矢量提取单元(前端处理)、训练单元、识别单元和后处理单元组成， -Commonly used methods of speaker recognition template matching method, statistical modeling method, and connection method (ie, artificial neural networks). Taking into account the amount of data, real-time as well as the recognition rate of the problem, based on vector quantization and Hidden Markov Model (HMM) method of combining. Speaker recognition system mainly by the voice feature vector extraction unit (front-end treatment), training modules, identification and post-treatment unit modules,

数字频率计的设计可以分为测量计数和显示。其测量的基本原理是计算一定时间内待测信号的脉冲个数，这就要求由分频器产生标准闸门时间信号，计数器记录脉冲个数，由控制器对闸门信号进行选择，并对计数器使能断进行同步控制。控制器根据闸门信号确定最佳量程。-The design of digital frequency meter can be divided into measurement and display count. The basic principle of its measurement is calculated under test signal within a certain period of time the number of pulses, which have a standard requirement by the divider gate time signal pulse counter records the number of signals from the controller to choose the gates and counters to make off synchronous control can be carried out.Controller based on the gate signal to determine the optimum range.
