  • The USB Multi-Interface driver is a replacement driver for the system provided Multi-Interface drive

    The USB Multi-Interface driver is a replacement driver for the system provided Multi-Interface driver. This driver was developed to overcome some bugs that are included in the build in driver and to introduce new features. The driver is compatible to the system provided Multi-Interface driver. If the driver is installed on a system, it does not automatically replace the system provided driver. It exists parallel to the system driver and is assigned to a device during the installation process.

  • Dual USB High-Side Power Switch

    The SP2526A device is a dual +3.0V to +5.5V USB Supervisory Power Control Switch ideal for self-powered and bus-powered Universal Serial Bus (USB) applications. Each switch has low on-resistance (110mΩ typical) and can supply 500mA minimum. The fault currents are limited to 1.0A typical and the flag output pin for each switch is available to indicate fault conditions to the USB controller. The thermal shutdown feature will prevent damage to the device when subjected to excessive current loads. The undervoltage lockout feature will ensure that the device will remain off unless there is a valid input voltage present.

  • USB接口HID驱动程序设计

    【摘要】:随着USB接口在计算机业界应用越来越广泛,基于USB的接口开发显得越来越具有现实意义。随着客户对系统数据采集速度要求的不断提高,USB以其使用方便、易于扩展、速度快等优点而越来越多的被应用于各种人机接口设备中。本设计提出了一种USB接口的HID数据通讯接口设计方案,USB接口芯片采用的是PHILIP的PDIUSBD12,微控器是宏晶科技的STC89C52RC。该方案具有器件通用、成本低、方便焊接调试等特点。由于本设计采用了PDIUSBD12接口芯片,通过改变微控器的代码可以制作成各种标准的USB设备。本设计完成了一种典型的HID设备驱动程序的开发,PC机无需额外加装驱动便可实现和USB设备之间的通讯。而且经过典型HID设备的枚举过程,还可用于对USB协议的熟悉和学习。上位机软件部分,采用了VisualC++6.0编写HID设备的控制程序,此控制程序和HID下位机设备构成了完整的USB控制系统。在此基础上,本设计还增加了简单的音乐播放功能,可以打开并播放格式为mp3和wma的音频文件,还可以暂停、停止、选择播放曲目、调节音量等;在音频播放时HID设备彩灯可以实时显示音频的频谱。这在验证USB系统的同时,大大增加了控制的趣味性。验证结果表明按照该方案设计的数据通讯接口和HID设计运行稳定可靠。USB是一种计算机和外部设备进行通讯连接的接口.USB的出现的目的是取代现在计算机接口,简化计算机与外部设备的连接过程,使计算机的扩展更加方便。它使得计算机和外部设备的连接十分方便。目前,各种计算机外部设备都在逐渐改为USB接口,USB技术的出现是计算机接口技术的一大飞跃。越来越多的测控系统、信号处理系统和智能仪器选用USB接口与PC机进行高速、海量的数据通讯。但是,相对UART(通用异步串口)、LPT(打印机并行端口),USB的开发难度要大的多。采用HID(Human Interface Device,人机接口设备)的设计方案则可以很好的解决这一矛盾。
