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.

為解決當(dāng)前計(jì)算機(jī)串行通訊接口只有USB，難以滿足舊型號(hào)設(shè)備或某些單片機(jī)要求RS232通訊的問題，設(shè)計(jì)出兩款RS232/USB電路。采用CH341A與MAX223集成電路芯片構(gòu)建標(biāo)準(zhǔn)9線RS232/USB通用接口轉(zhuǎn)換器，無需編程。采用CH341A與PIC16F877A構(gòu)建單片機(jī)與計(jì)算機(jī)之間的USB通訊電路，軟件遵循RS232通訊協(xié)議，硬件進(jìn)行電平轉(zhuǎn)換。實(shí)際使用表明，這兩款產(chǎn)品與計(jì)算機(jī)端Windows 操作系統(tǒng)下的串口應(yīng)用程序完全兼容，且通訊過程中無握手失敗現(xiàn)象。 Abstract: To solve the problem that current computer serial communication only with USB interface can not satisfy with the old type equipments or MCU to communicate with RS232， two kinds of RS232/USB circuit were designed.CH341A and MAX223 integrated circuit chips were used to create a standard 9-line RS232/USB universal interface convertor without programme. CH341A and PIC16F877A chips were adopted to build the USB communication circuit between computers and MCU. The software follows RS232 communication protocol， and the hardware converts electrical levels. Actual practices indicate that the two manufactures are compatible with serial application program of Windows operation system completely，and get avoid of handshake lost.

以AVR單片機(jī)ATmega8和USB接口器件PDIUSBD12為核心，基于標(biāo)準(zhǔn)的USB1.1協(xié)議，設(shè)計(jì)一種通用USB接口模塊，以滿足嵌入式系統(tǒng)中對(duì)USB接口的需求。對(duì)模塊的硬件電路或單片機(jī)固件程序的硬件接口層稍加修改即可用于其他各種微處理器。該模塊可為各種嵌入式系統(tǒng)增加USB接口,實(shí)現(xiàn)與USB主機(jī)系統(tǒng)通信。 Abstract: Based on AVR microcontroller ATmega8 and USB interface chip PDIUSBD12, a general USB interface module is designed according to USB1.1 protocol for various requirements of embedded systems. Only with few modifications in circuit or hardware abstract layer of firmware, the module can be used on many types of microprocessors. All kinds of embedded systems can realize high speed and stable communication with USB host systems, owing to the facility of this module.

The MSP-FET430U14 is a powerful flash emulation tool to quickly begin application development on the MSP430 MCU. It includes USB debugging interface used to program and debug the MSP430 in-system through the JTAG interface or the pin saving Spy Bi-Wire (2-wire JTAG) protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is ultra-low power, no external power supply is required. The debugging tool interfaces the MSP430 to the included integrated software environment and includes code to start your design immediately. The MSP-FET430UIF development tools supports development with all MSP430 flash devices

PICKIT™ 2 PROGRAMMER-TO-GO USER GUIDE The PICkit 2 Programmer-To-Go functionality allows a PIC MCU memory image to be downloaded into the PICkit 2 unit for later programming into a specific PIC MCU. No software or PC is required to program devices once the PICkit 2 unit is set up for Programming-To-Go. A USB power source for the PICkit 2 is all that is needed.
