stm32开发板原理图，里面扩展了SD卡，液晶屏，USB口，以及音频接口

（一）基本任务：单频正弦波模拟信号的简单数字化。即对一个单频正弦波模拟信号进行抽样、均匀量化、PCM二进制自然编码。 1、主要步骤和要求： （1）单频正弦波模拟信号的抽样实现。要求输入信号的幅度A、频率F和相位P可变；要求仿真时间从0到2/F，抽样频率为Fs=20F；要求给出抽样信号samp的波形图。 （2）单频正弦波模拟信 ...

Bootloading the TMS320VC5506/C5507/C5509 A digital signal processor (DSP) through the on-chip universal serial bus (USB) peripheral is part of the standard bootloader provided on the device. This document describes the procedures for physically connecting the DSP to a USB host, invoking the USB boot ...

This software package contains the USB framework core developped by ATMEL, as well as two HID drivers for a mouse and a keyboard. The following files are included : - core/ -> Source code for the framework core -> Makefile for the core - hid/ -> Source code for the HID drivers -> Makefile ...

通过MATLAB编程实现自动输出A矩阵，输出图的一棵树，输出图的所有的树

Z-TEK USB转RS232串口驱动文件，网上很难找到，今天我吧它贴出来，希望能帮助大家！

很好的制作AVR USB编程器的资料，内含原理图、代码等。

Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel conversion, bit stuffing/unstuffing, NRZI encoding decoding. Uses a simplified UTMI interface. Currently doesn t do any error checking in the RX section [should probably check for bit unstuffing errors]. Otherwise complete and fully ...

Although some FX1-based devices may use the FX1鈥檚 CPU to process USB data directly (Port I/O Mode), most applica- tions use the FX1 simply as a conduit between the USB and external data-processing logic (e.g., an ASIC or DSP, or the IDE controller on a hard disk drive).
