The PMSM FOC is made of several C modules, compatible with the free-of-charge IAR EWARM KickStart edition toolchain version 4.42. It is used to quickly evaluate both the MCU and the available tools. In addition, when used together with the STM32F103xx motor control starter kit (STM3210B-MCKIT) and PM motor, a motor can be made to run in a very short time. It also eliminates the need for time-consuming development of FOC and speed regulation algorithms by providing ready-to-use functions that let the user concentrate on the application layer. Moreover, it is possible to get rid of any speed sensor thanks to the sensorless algorithm for rotor position reconstruction.

在采用多道程序设计的系统中，往往有若干个进程同时处于就绪状态。当就绪进程个数大于处理机数时，就必须依照某种策略来决定哪些进程优先占用处理机。本实验模拟在单处理机情况下的处理机调度，帮助学生加深了解处理机调度的工作。 二、实验类型 设计型。 三、预习内容 预习课本处理机调度有关内容，包括进程占用处理机的策略方法。 四、实验要求与提示 设计进程调度算法，进程数不定；包含几种调度算法，并加以实现；输出进程的调度过程——进程的状态、链表等。要求使用优先权法和轮转法模拟进程调度过程。 【提示】：简化假设 1） 进程为计算型的（无I/O） 2） 进程状态：ready、running、finish 3） 进程需要的CPU时间以时间片为单位确定 【提示】：算法描述 1） 优先权法——动态优先权，当前运行进程用完时间片后，其优先权减去一个常数。 2） 轮转法

This application report presents basic code for initializing and operating the TMS320LF240x DSP devices. Two functionally equivalent example progra ms are presented: one written in assembly language and the other in C language. Detailed discussions of each program are provided that explain numerous compiler and assembler directives, code requirements, and hardware-related requirements. The programs are ready to run on either the TMS320LF2407 Evaluation Module (EVM) or the eZdsp LF2407 development kit. However, they are also intended for use as a code template for any TMS320LF240x (LF240x) or TMS320LF240xA (LF240xA) DSP target system.

Introduction Computer security is undeniably important, and as new vulnerabilities are discovered and exploited, the perceived need for new security solutions grows. "Trusted computing" initiatives propose to solve some of today s security problems through hardware changes to the personal computer. Changing hardware design isn t inherently suspicious, but the leading trusted computing proposals have a high cost: they provide security to users while giving third parties the power to enforce policies on users computers against the users wishes -- they let others pressure you to hand some control over your PC to someone else. This is a "feature" ready-made for abuse by software authors who want to anticompetitively choke off rival software. It needn t be this way: a straightforward change to the plans of trusted computing vendors could leave the security benefits intact while ensuring that a PC owner s

这个是我调通的在2410下运行文件系统的程序. 用2410驱动sd卡来实现fat文件系统. 欢迎大家来测试. 用法很简单, 如下 FILE *fp // 文件指针 unsigned char temp[24]="3.wav" // 文件明需要放在数组里 while(!initialize_media()) // 初始化sd卡 { Uart_Printf("sd initializing....\n") } Uart_Printf("sd ready\n") fp=fopen(temp, READ) // 打开文件就可以用了， 函数和标准c中的一样,所以不能加载stdio.h if(!fp) { Uart_Printf("open file wrong\n") while(1) } Uart_Printf("open file successed\n")

1，初始化： 如果AD7705复位引脚直连VCC，最好在初始化程序中加入初始化序列，不然ready信号不会输出。 2，输入范围 如果AD7705采集单端信号，则输入必须在0到VDD之间，而不可以超出或为负，如果一个输入为负，则另一个输入会有灌入电流的现象，芯片无法正常运行。

Since the advent of optical communications, a great technological effort has been devoted to the exploitation of the huge bandwidth of optical fibers. Start- ing from a few Mb/s single channel systems, a fast and constant technological development has led to the actual 10 Gb/s per channel dense wavelength di- vision multiplexing (DWDM) systems, with dozens of channels on a single fiber. Transmitters and receivers are now ready for 40 Gb/s, whereas hundreds of channels can be simultaneously amplified by optical amplifiers.
