CH375 是一個USB總線的通用接口芯片，支持USB-HOST主機方式和USB-DEVICE/SLAVE設備方式。在本地端，CH375具有8位數據總線和讀、寫、片選控制線以及中斷輸出，可以方便地掛接到單片機/DSP/MCU/MPU等控制器的系統總線上。在USB主機方式下CH375還提供了串行通訊方式，通過串行輸入、串行輸出和中斷輸出與單片機/DSP/MCU/MPU 等相連接。 CH375 的USB 設備方式與CH372 芯片完全兼容，CH375 包含了CH372 的全部功能。本手冊中沒有提供CH375 在USB 設備方式下的說明，相關資料可以參考CH372 手冊。 CH375的USB 主機方式支持常用的USB 全速設備，外部單片機可以通過CH375 按照相應的USB 協議與USB 設備通訊。CH375 還內置了處理Mass-Storage 海量存儲設備的專用通訊協議的固件，外部單片機可以直接以扇區為基本單位讀寫常用的USB 存儲設備（包括USB 硬盤/USB 閃存盤/U 盤）。

pic mcu code:This application note describes the design and implementation of a USB Mass Storage Device (MSD) using a Secure Digital card, which should prove useful to developers of USB mass storage solutions. This application may be used as a stand-alone MSD or as a Secure Digital/Multimedia Card (SD/MMC) reader/ writer interface.

Writing an Input Module The sample module introduced here is called idiom (Input Device for Intercepting Output of Mice), The sample module registers itself with the USB kernel subsystem as a mouse driver and with the input management subsystem as a keyboard driver. idiom translates mouse movement events into keyboard input events: it reports arrow events to the input system according to how the physical mouse is moved.

This application note describes a method for developing block-oriented I/O device drivers for applications that use the DSP/BIOS real-time kernel and includes examples that run with Code Composer Studio v2.1 on the Texas Instruments TMS320C5402 and TMS320C6711 DSP Starter Kits (DSKs). The device driver model presented here has now been superceded with an updated version that supports not only block oriented devices, but also devices such as UARTs, PCI and USB buses and Multimedia cards. Documentation on the updated driver model as well as example drivers and source code can be found in the Device Driver Developer s Kit product now available for download from the TI Developer s Village.

This C++ code example provides a method for transferring objects or chunks of data from one device to another via the Bluetooth OBEX protocol. These chunks are typically files or other blocks of binary data. This example demonstrates how to run OBEX on top of the Bluetooth RFCOMM protocol, but OBEX can also be used with other transport media, such as IrDA and USB.

Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices at startup or when they are plugged in at run time. These devices are broken into various device classes. Each device class defines the common behavior and protocols for devices that serve similar functions. Some examples of USB device classes are shown in the following table

DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, device-specific code to access hardware such as the display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.
