Description: 用LPC213X系列的PWM来产生语音。语音数据来源于PC机转换后得到的。最大可以是16位的。
由于是PWM所以输出端口需要低通滤波才能够得到比较干净的声音。
可以经过修改使用LPC2132以上的ARM的D/A来产生。
This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM. -LPC213X series used to generate the PWM voice. Voice data from the PC after the conversion. It is the largest of 16. Because there is PWM output ports need low-pass filter can be relatively clean voice. It has been modified over the use LPC2132 ARM D / A to produce. This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.

Description: This project is created using the Keil ARM CA Compiler.
The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1
This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series.
You may create various input signals like digital pulses, sine waves, sawtooth waves, and square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.

Description: 无刷直流电机控制系统的研究与实现
简单介绍了无刷直流电动机的工作原理，分析并确定了主回路的导通方式，控制器一是以专用芯片MC33035来进行设计，位置反馈元件有霍尔传感器反馈接口和编码器接口，开关器件采用MOSFET管，设计有转速反馈闭环控制、正反转、过电流保护等。控制器还采用89C52单片机、 MAX7219、AD667等来实现数字转速给定和转速显示。控制器二是基于PICSF4431电动机控制专用芯片，采用全数字PID控制，有转速、电流双反馈，位置反馈采用编码器反馈，开关器件采用IGBT，在PWM输出端有GAL芯片保护，防止上下桥臂直通。在控制器二中，备有两套程序，程序一是没有进行外加给定值采样，采用两两PWM全导通方式，在此情况下，电机的转矩波动明显，程序二中采用PWM导通方式，电机的转矩波动较小，运行性能较好。
