  • 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驅(qū)動(dòng)程序設(shè)計(jì)

    【摘要】:隨著USB接口在計(jì)算機(jī)業(yè)界應(yīng)用越來(lái)越廣泛,基于USB的接口開發(fā)顯得越來(lái)越具有現(xiàn)實(shí)意義。隨著客戶對(duì)系統(tǒng)數(shù)據(jù)采集速度要求的不斷提高,USB以其使用方便、易于擴(kuò)展、速度快等優(yōu)點(diǎn)而越來(lái)越多的被應(yīng)用于各種人機(jī)接口設(shè)備中。本設(shè)計(jì)提出了一種USB接口的HID數(shù)據(jù)通訊接口設(shè)計(jì)方案,USB接口芯片采用的是PHILIP的PDIUSBD12,微控器是宏晶科技的STC89C52RC。該方案具有器件通用、成本低、方便焊接調(diào)試等特點(diǎn)。由于本設(shè)計(jì)采用了PDIUSBD12接口芯片,通過(guò)改變微控器的代碼可以制作成各種標(biāo)準(zhǔn)的USB設(shè)備。本設(shè)計(jì)完成了一種典型的HID設(shè)備驅(qū)動(dòng)程序的開發(fā),PC機(jī)無(wú)需額外加裝驅(qū)動(dòng)便可實(shí)現(xiàn)和USB設(shè)備之間的通訊。而且經(jīng)過(guò)典型HID設(shè)備的枚舉過(guò)程,還可用于對(duì)USB協(xié)議的熟悉和學(xué)習(xí)。上位機(jī)軟件部分,采用了VisualC++6.0編寫HID設(shè)備的控制程序,此控制程序和HID下位機(jī)設(shè)備構(gòu)成了完整的USB控制系統(tǒng)。在此基礎(chǔ)上,本設(shè)計(jì)還增加了簡(jiǎn)單的音樂(lè)播放功能,可以打開并播放格式為mp3和wma的音頻文件,還可以暫停、停止、選擇播放曲目、調(diào)節(jié)音量等;在音頻播放時(shí)HID設(shè)備彩燈可以實(shí)時(shí)顯示音頻的頻譜。這在驗(yàn)證USB系統(tǒng)的同時(shí),大大增加了控制的趣味性。驗(yàn)證結(jié)果表明按照該方案設(shè)計(jì)的數(shù)據(jù)通訊接口和HID設(shè)計(jì)運(yùn)行穩(wěn)定可靠。USB是一種計(jì)算機(jī)和外部設(shè)備進(jìn)行通訊連接的接口.USB的出現(xiàn)的目的是取代現(xiàn)在計(jì)算機(jī)接口,簡(jiǎn)化計(jì)算機(jī)與外部設(shè)備的連接過(guò)程,使計(jì)算機(jī)的擴(kuò)展更加方便。它使得計(jì)算機(jī)和外部設(shè)備的連接十分方便。目前,各種計(jì)算機(jī)外部設(shè)備都在逐漸改為USB接口,USB技術(shù)的出現(xiàn)是計(jì)算機(jī)接口技術(shù)的一大飛躍。越來(lái)越多的測(cè)控系統(tǒng)、信號(hào)處理系統(tǒng)和智能儀器選用USB接口與PC機(jī)進(jìn)行高速、海量的數(shù)據(jù)通訊。但是,相對(duì)UART(通用異步串口)、LPT(打印機(jī)并行端口),USB的開發(fā)難度要大的多。采用HID(Human Interface Device,人機(jī)接口設(shè)備)的設(shè)計(jì)方案則可以很好的解決這一矛盾。
