Freescale-Chapter-8

pscad的单相接地故障仿真，按照教程还原版，文中自带仿真结果(pscad of single-phase ground fault simulation, follow the tutorial also the original, the paper comes with simulation results)

说明：  介绍了ccs6.2的详细使用步骤，以及TMS3206678手册(The detailed steps of ccs6.2 are introduced)

说明：  kissfft，简单的快速傅里叶变换，重新爱上fft在单片机上的实现。(Kissfft, simplified fast Fourier transform.:))

WM8731是高性能的音频编码解码芯片，使用时需要通过IIC总线进行配置，本程序可以直观的设置各寄存器的参数，并自动生成C或C++语言代码。使用方便。(WM8731 is a high-performance audio codec chip, need to use IIC bus configuration, this procedure can be intuitively set the parameters of the register, and automatically generate C or C++ language code. Easy to use.)

在下的毕业设计，　　　本题要求设计一个直流电机控制系统。在设计中，采用国产单片机中目前比较新式的STC12C5A60S2作为整个控制系统的控制电路的核心，因为STC12C5A60S2内部有PCA模块，可以产生PWM波形；采用带中断的独立式键盘作为命令的输入，每当按键时蜂鸣器响；配以LCD12864显示实现对带光码盘的直流电动机转速参数的测量、显示和控制。LMD18200驱动模块内部是H型驱动电路，驱动能力较强，完成电机正反转以及速度的控制。为优化直流电机的响应，采用PID反馈，实现闭环控制。(Graduation in the next, and that the requirements to design a DC motor control system. In the design, the use of the relatively new domestic microcontroller as a control circuit of STC12C5A60S2 entire control system core, because STC12C5A60S2 internal PCA module can generate PWM waveforms using a separate keyboard with interrupt input as a command, whenever the button When the buzzer sounds accompanied LCD12864 display realize the measurement of the optical encoder with DC motor speed parameters, display and control. LMD18200 internal drive module is H-drive circuit, driving ability, and the speed of completion of the motor reversing control. In order to optimize the response of DC motor, using PID feedback, closed loop control.)

说明：  基于STM32的定时器的一些简单开发和应用(Simple development application of STM32)

华为智能光伏电站解决方案设计图纸，包括子阵布局，逆变器，选配件，无线部分，监控系统，逆变器安装，一次系统等(HUAWEI smart photovoltaic power plant solutions design drawings, including sub array layout, inverter, accessories, wireless parts, monitoring system, inverter installation, a system, etc.)

1. 书中所有源程序, 在CPP子目录下, CPP.EXE是压缩可自释放的文件, 在DOS 下运行该文件即可释放 2. 书中程序的部分演示程序(源程序的编译), 在DEMO子目录下, 运行压缩文件 DEM.EXE释放, 然后运行DEMO.BAT演示 3. 精简UCDOS 3.0汉字系统, 含一个24点阵宋体字库, 在UCDOS子目录下, 运行 UCD.EXE释放。(1. The book all the source code, in the CPP, under a subdirectory, CPP.EXE is available since the release of compressed files, in DOS the file can be run under release 2. Book procedures demo programs (source code compiler), in the DEMO subdirectory, run DEM.EXE the release of compressed file, and then run DEMO.BAT presentation 3. UCDOS 3.0 to streamline the system of Chinese characters, including a 24-dot matrix font宋体in UCDOS subdirectory, run UCD.EXE release.)

说明：  本程序利用51单片机实现点对多点的数据传输，包括相应的电路图(This procedure using 51 single-chip realization of point-to-multipoint data transmission, including the corresponding circuit diagram)
