Logger iButton DEVICES have gained a lot of popularity with researchers. Although free evaluation software is easy to use and welldocumented, the choices and inputs that need to be made can sometimes be challenging. This application note explains technicalterms that are common with temperature logger iButtons and how they relate to each other. Additionally, it presents an algorithm tohelp users choose the necessary input parameters, including the sample rate based on a user's needs and the available memory tostore the data.

The high defi nition multimedia interface (HDMI) is fastbecoming the de facto standard for passing digitalaudio and video data in home entertainment systems.This standard includes an I2C type bus called a displaydata channel (DDC) that is used to pass extended digitalinterface data (EDID) from the sinkdevice (such as adigital TV) to the source device (such as a digital A/Vreceiver). EDID includes vital information on the digitaldata formats that the sink device can accept. The HDMIspecifi cation requires that DEVICES have less than 50pFof input capacitance on their DDC bus lines, which canbe very diffi cult to meet. The LTC®4300A’s capacitancebuffering feature allows DEVICES to pass the HDMI DDCinput capacitance compliance test with ease.

Semiconductor memory, card readers, microprocessors,disc drives, piezoelectric DEVICES and digitally based systemsfurnish transient loads that a voltage regulator mustservice. Ideally, regulator output is invariant during a loadtransient. In practice, some variation is encountered andbecomes problematic if allowable operating voltage tolerancesare exceeded. This mandates testing the regulatorand its associated support components to verify desiredperformance under transient loading conditions. Variousmethods are employable to generate transient loads, allowingobservation of regulator response

為了改進產品性能和兼容性,最新的HDMI compliance test specification (HDMI CTS) V.1.3增加了新的測試內容和定下了更嚴格的標準。大多數現在遞交給HDMI授權測試中心(ATC) 的帶有HDMI功能的電器都將按照HDMI CTS V.1.3 來測試。Analog DEVICES (ADI) 分別在美國的綠堡(Greensboro,NC), 東京, 臺灣和北京設立了四家預測試中心為客戶提供HDMI CT 測試以縮短客戶產品上市的時間。在本文中我們將討論HDMI CTS V.1.3新增加的一些重要內容。同時我們也將著重總結一些典型測試項目失敗的原因和可能的修改方案。

There are many manufacturers of dot matrix LCD modules. However, most of these displaysare similar. They all have on-board controllers and drivers capable of displaying alpha numericsand a wide variety of other symbols (including Japanese "Katakana" characters). The internaloperation of LCD controller DEVICES is determined by signals sent from a central processing unit(in this case, a CoolRunner-II CPLD).

SL811開發資料_包含源程序_電路圖_芯片資料:SL811HS Embedded USB Host/Slave Controller.The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to DEVICES such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O DEVICES, and a custom BIOS. Currently, Bochs can be compiled to emulate a 386, 486, Pentium, Pentium Pro or AMD64 CPU, including optional MMX, SSE, SSE2 and 3DNow! instructions. Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS, Windows 95/98 and Windows NT/2000. Bochs was written by Kevin Lawton and is currently maintained by the Bochs project at "http://bochs.sourceforge.net".

LPC2148 USB Audio Device Example This USB example project implements an USB Audio Device that connects via the USB interface to the PC. It may be used on the following DEVICES: LPC2141 LPC2142 LPC2144 LPC2146 LPC2148 An USB Audio Device (HID) does not require any special USB driver, since the USB Audio support is already built into Windows 2000 and Windows XP. Therefore USB Audio DEVICES can be directly connected to the computer. This example project is designed to work with Keil MCB2140 Evaluation Board. Refer to Running USBAudio for information on how to operate this example project.
