單片機(jī)讀寫(xiě)U盤(pán)的模塊 USB118 _不用電腦也能讀寫(xiě)U盤(pán)中的文件！ ■ 型 號(hào): USB118AD USB118A 關(guān)鍵詞：U盤(pán)、單片機(jī)、USB2.0、USB Host、USB主設(shè)備、設(shè)備黑匣子、數(shù)據(jù)記錄 ■ 簡(jiǎn) 介 目前，基于USB2.0接口的移動(dòng)存儲(chǔ)設(shè)備已經(jīng)被廣泛使用，尤其是采用USB-FLASH技術(shù)的U盤(pán)產(chǎn)品的容量由幾年前的16M增加到現(xiàn)在的4G以上。我們知道，U盤(pán)通常是作為計(jì)算機(jī)的外部存儲(chǔ)設(shè)備，能否脫離計(jì)算機(jī)直接向U盤(pán)讀寫(xiě)文件呢？答案是肯定的。USB118系列嵌入式U盤(pán)讀寫(xiě)模塊提供了通過(guò)串口或SPI口讀寫(xiě)U盤(pán)的簡(jiǎn)單途徑，由此結(jié)合單片機(jī)的RS232串口或高速SPI總線就可以實(shí)現(xiàn)對(duì)U盤(pán)上的文件讀寫(xiě)。 USB118AD型高速U盤(pán)讀寫(xiě)模塊是對(duì)USB118A模塊的性能進(jìn)行改進(jìn)后的USB2.0接口的高速模塊，具有與USB118A模塊完全兼容的串口，同時(shí)增加了高速的SPI接口，主要應(yīng)用于便攜儀器或者嵌入式數(shù)據(jù)采集系統(tǒng)的外掛式海量存儲(chǔ)。 ■ 特 征 ◆ 不必了解USB協(xié)議，直接嵌入用戶系統(tǒng) ◆ 兼容1G以上U盤(pán)、移動(dòng)硬盤(pán) ◆ USB2.0接口，提供USB HOST接口 ◆ RS232串口波特率：57600/115200/9600bps ◆ 高速SPI接口文件傳輸速度：150KByte/Sec ◆ 支持文件系統(tǒng)：FAT16/FAT32 ◆ 創(chuàng)建Word、 Excel、二進(jìn)制等各種類型文件 ◆ 提供單片機(jī)編程實(shí)例C51源代碼 ◆ 提供模塊測(cè)試板及電腦串口測(cè)試軟件 ◆ 直流5V供電，電流100mA(不含U盤(pán)) ◆ 模塊只有火柴盒大小：51.6×43×12mm ■ 應(yīng) 用 ◆ 海量數(shù)據(jù)采集存儲(chǔ) ◆ 設(shè)備黑箱子 ◆ 考勤機(jī)數(shù)據(jù)記錄 ◆ 石油儀器儀表 ◆ 紡織機(jī)械 ◆ 水文監(jiān)測(cè) ◆ 無(wú)紙記錄儀

The LTC®4099 high effi ciency USB power manager andLi-Ion/Polymer battery charger seamlessly managespower distribution from multiple sources in portableapplications. It is differentiated from other USB powermanagers by its bidirectional I2C port that allows the hostmicroprocessor to control and monitor all aspects of theUSB power management and battery charging processes.In addition, a programmable interrupt generation functionalerts the host microprocessor to changes in device statusand provides unprecedented control of power managementfunctions. This high degree of confi gurability allowspost-layout changes in operation, even changes in thefi eld, and it allows a single qualifi ed device to be usedin a variety of products, thus reducing design time andeasing inventory management.

The PL2303 USB to Serial adapter is your smart and convenient accessory forconnecting RS-232 serial devices to your USB-equipped Windows host computer. Itprovides a bridge connection with a standard DB 9-pin male serial port connector inone end and a standard Type-A USB plug connector on the other end. You simplyattach the serial device onto the serial port of the cable and plug the USB connectorinto your PC USB port. It allows a simple and easy way of adding serial connectionsto your PC without having to go thru inserting a serial card and traditional portconfiguration.This USB to Serial adapter is ideal for connecting modems, cellular phones, PDAs,digital cameras, card readers and other serial devices to your computer. It providesserial connections up to 1Mbps of data transfer rate. And since USB does not requireany IRQ resource, more devices can be attached to the system without the previoushassles of device and resource conflicts.Finally, the PL-2303 USB to Serial adapter is a fully USB Specification compliantdevice and therefore supports advanced power management such as suspend andresume operations as well as remote wakeup. The PL-2303 USB Serial cable adapteris designed to work on all Windows operating systems.

This firmware translates a PS/2 mouse to a USB mouse. The translator firmware is entirely interrupt driven (with the exception of sending the data via USB to the host.) An interrupt is generated when the PS/2 start bit is received, at which time the firmware will begin its receive routine. In addition to this interrupt, every 168ms a timer overflow interrupts the main program and implements one state of the mouse state machine. This state machine handles sending bytes to and translating bytes received from the PS/2 mouse automatically. All of this is done in the background while the main program runs in the foreground. The only operation that the main program implements is sending mouse data to the PC via USB.
