USB开发工具，MS提供，可以读取所有USB设备的descriptor表。是USB开发者的好帮手。-USB development tools, MS to provide, you can read all the USB device descriptor table. USB developer is a good helper.

这是一个PL2303适配器与JTAG冰，虽然，或串行通信，但我认为是非常方便和紧凑。驱动芯片74HC245I这里更多，所以没有244，是一样的。Mega16L选择TQFP包。

USB驱动传输数据握手的例程。还有类似的很多程序，需要的话请留言免费赠送。-USB drive to transfer data handshake routines.

usb 设计参考资料 可以借鉴 usb1.1-usb reference design can draw on USB1.1

本程序包是USB开发主机系统的例程序。-This package is the USB host system"s development process cases.

CH372 是一个USB 总线的通用设备接口芯片，是CH371的升级产品，是CH375芯片的功能简化版。在本地端，CH372 具有8 位数据总线和读、写、片选控制线以及中断输出，可以方便地挂接到单片机/DSP/MCU/MPU等控制器的系统总线上；在计算机系统中，CH372 的配套软件提供了简洁易用的操作接口，与本地端的单片机通讯就如同读写文件。 　　CH372 内置了USB 通讯中的底层协议，具有省事的内置固件模式和灵活的外置固件模式。在内置固件模式下，CH372自动处理默认端点0 的所有事务，本地端单片机只要负责数据交换，所以单片机程序非常简洁。在外置固件模式下，由外部单片机根据需要自行处理各种USB 请求，从而可以实现符合各种USB 类规范的设备。-err

mp3设计程序资料，采用c语言编写。 README file for yampp-3 source code 2001-05-27 This is the current state of the yampp-3 source code, 2001-05-27. This code is intended to run on Rev. B of the yampp-3 PCB, but can ofcourse be used on compatible systems as well. It still uses the "old" song selection system as the yampp-2. However, the disk handling routines has improved a lot and the obviosly, the new VS1001 handling has been put in. The codesize is almost at it s maximum at 1F40 bytes. A .ROM file is included if you don t have the compiler set up. For now, the documentation is in the code- mp3 programming cook book in C.
