    Please read this document BEFORE attempting to compile and run the libraries and applications! The projects must be compiled in a particular order. Standard support questions are about compiler and/or linker errors that are generated when users try to compile the projects in the wrong order. Other information of interest is available here, so read the entire document fi rst. Wild Magic Version 2.1 is what ships with the fi rst printing of the Game Physics book. Some of the applications that are referenced in the book did not make it onto the CD–ROM for the book. Version 2.2 contains those applications, plus more

    This is the procedure for lab 1. This is a two-week lab. Prelab should be done BEFORE going to the lab session. In this lab the dielectric properties of materials and how these properties affect electric fields will be analized.

    This approach, we feel, came very close to obtaining an image from the camera OV7620. BEFORE we tried to capture a camera signal, we successfully transferred a test image from the FPGA s onboard RAM modules through RS232 to the PC program. This file do it.

    BEFORE you even get started on your PhD research, you have already made a decision that will have a major impact on the success of your project, and perhaps even on your future career. You have chosen to work in a particular research group, under the guidance of a particular thesis advisor or supervisor.

  • LED的电源管理

    A light-emitting diode (LED) is a semiconductor device that emits narrow-spectrum incoherent light when forward-biased.The color of the emitted light depends on the chemical composition of the semiconductor material used, and can benear-ultraviolet, visible or infrared. LEDs are more prevalent today than ever BEFORE, replacing traditional incandescent andfluorescent bulbs in many lighting applications. Incandescents use a heated filament, are subject to breakage and burnoutand operate at a luminous efficiency of 2% to 4%. Fluorescents are more efficient, at 7% to 12%, but require highdrive voltage and contain mercury, a toxic substance that may be eventually banned in certain countries. LEDs, however,produce light directly through electroluminescence, operate at low voltage and can deliver over 20% luminous efficiency.

  • 无线通信网络基本概念及设计

    This white paper raises some fundamental issues the design engineer should address BEFORE deciding upon a communication approach for a wireless network. As no universal wireless network solution exists, it should be custom tailored to suit the application demands. Defining your application communication characteristics is the key to ensure optimal communication reliability and resistance to interfering noise sources.

  • MAXX9257 MAX9258芯片可编程SerDes持续时间计算

    The MAX9257/MAX9258 programmable serializer/deserializer (SerDes) devices transfer both video data and control signals over the same twisted-pair cable. However, control data can only be transmitted during the vertical blank time, which is indicated by the control-channel-enabled output (CCEN) signal. The electronic control unit (ECU) firmware designer needs to know how quickly to respond to the CCEN signal BEFORE it times out and how to calculate this duration. This application note describes how to calculate the duration of the CCEN for the MAX9257/MAX9258 SerDes chipset. The calculation is based on STO timeout, clock frequency, and UART bit timing. The CCEN duration is programmable and can be closed if not in use.

  • Atmel AT89C系列单片机电路板设计指南

    Designing Boards with Atmel AT89C51,AT89C52, AT89C1051, and AT89C2051 for Writing Flash at In-Circuit Test. Recent improvements in chips and testers have made it possible for the tester to begin taking over the role tradi-tionally assigned to the PROM program-mer. Instead of having a PROM pro- grammer write nonvolatile memories BEFORE assembling the board, the in-cir- cuit tester writes them during in-circuit testing operations. Many Teradyne Z18- series testers are now in use loading code into nonvolatile memories, micro- controllers and in-circuit programmable logic devices. The purpose of this note is to explain how the Z18 approaches the writing task for Atmel AT89C series IC’s, so that designers of boards using these chips can get the best results.

  • 基于MSP430F1611单片机的音频信号分析仪设计

      为了使音频信号分析仪小巧可靠,成本低廉,设计了以2片MSP430F1611单片机为核心的系统。该系统将音频信号送入八阶巴特沃兹低通滤波器,对信号进行限幅放大、衰减、电平位移、缓冲,并利用一单片机负责对前级处理后的模拟信号进行采样,将采集得到的音频信号进行4 096点基2的FFT计算,并对信号加窗函数提高分辨率,另一单片机负责对信号的分析及控制显示设备。此设计精确的测量了音频信号的功率谱、周期性、失真度指标,达到较高的频率分辨率,并能将测量结果通过红外遥控器显示在液晶屏上。   Abstract:   o make the audio signal analyzer cheaper, smaller and more reliable, this system sends the audio signal to the eight-order butterworth filter, and then amplifies, attenuates, buffers it in a limiting range, transfers the voltage level of the signal BEFORE utilizing two MSP430F1611 MCU to realize the audio analysis. One is charged for sampling and dealing with the processed audio signal collected by the 4096 point radix-2 FFT calculation and imposes the window function to improve the frequency resolution. The other one controls the display and realizes the spectrum, periodicity, power distortion analysis in high resolution which is displayed in the LCD screen through the infrared remote control.
