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.

在采用多道程序設計的系統(tǒng)中，往往有若干個進程同時處于就緒狀態(tài)。當就緒進程個數(shù)大于處理機數(shù)時，就必須依照某種策略來決定哪些進程優(yōu)先占用處理機。本實驗模擬在單處理機情況下的處理機調度，幫助學生加深了解處理機調度的工作。 二、實驗類型 設計型。 三、預習內(nèi)容 預習課本處理機調度有關內(nèi)容，包括進程占用處理機的策略方法。 四、實驗要求與提示 設計進程調度算法，進程數(shù)不定；包含幾種調度算法，并加以實現(xiàn)；輸出進程的調度過程——進程的狀態(tài)、鏈表等。要求使用優(yōu)先權法和輪轉法模擬進程調度過程。 【提示】：簡化假設 1） 進程為計算型的（無I/O） 2） 進程狀態(tài)：ready、running、finish 3） 進程需要的CPU時間以時間片為單位確定 【提示】：算法描述 1） 優(yōu)先權法——動態(tài)優(yōu)先權，當前運行進程用完時間片后，其優(yōu)先權減去一個常數(shù)。 2） 輪轉法

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

這個是我調通的在2410下運行文件系統(tǒng)的程序. 用2410驅動sd卡來實現(xiàn)fat文件系統(tǒng). 歡迎大家來測試. 用法很簡單, 如下 FILE *fp // 文件指針 unsigned char temp[24]="3.wav" // 文件明需要放在數(shù)組里 while(!initialize_media()) // 初始化sd卡 { Uart_Printf("sd initializing....\n") } Uart_Printf("sd ready\n") fp=fopen(temp, READ) // 打開文件就可以用了， 函數(shù)和標準c中的一樣,所以不能加載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復位引腳直連VCC，最好在初始化程序中加入初始化序列，不然ready信號不會輸出。 2，輸入范圍 如果AD7705采集單端信號，則輸入必須在0到VDD之間，而不可以超出或為負，如果一個輸入為負，則另一個輸入會有灌入電流的現(xiàn)象，芯片無法正常運行。

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.
