本代碼為編碼開關(guān)代碼,編碼開關(guān)也就是數(shù)字音響中的 360度旋轉(zhuǎn)的數(shù)字音量以及顯示器上用的(單鍵飛梭開 關(guān))等類似鼠標(biāo)滾輪的手動(dòng)計(jì)數(shù)輸入設(shè)備。 我使用的編碼開關(guān)為5個(gè)引腳的,其中2個(gè)引腳為按下 轉(zhuǎn)輪開關(guān)(也就相當(dāng)于鼠標(biāo)中鍵)。另外3個(gè)引腳用來 檢測(cè)旋轉(zhuǎn)方向以及旋轉(zhuǎn)步數(shù)的檢測(cè)端。引腳分別為a,b,c b接地a,c分別接到P2.0和P2.1口并分別接兩個(gè)10K上拉 電阻,并且a,c需要分別對(duì)地接一個(gè)104的電容,否則 因?yàn)榫幋a開關(guān)的觸點(diǎn)抖動(dòng)會(huì)引起輕微誤動(dòng)作。本程序不 使用定時(shí)器,不占用中斷,不使用延時(shí)代碼,并對(duì)每個(gè) 細(xì)分步數(shù)進(jìn)行判斷,避免一切誤動(dòng)作,性能超級(jí)穩(wěn)定。 我使用的編碼器是APLS的EC11B可以參照附件的時(shí)序圖 編碼器控制流水燈最能說明問題,下面是以一段流水 燈來演示。

Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources. Also in circuit switched networks many paths use the same links. This toolbox answers the question how different paths with different loads influence on each other and what is the blocking on each of the defined path. Toolbox is capable of computing blocking for three different WDM network types: with no wavelength conversion, with full wavelength conversion and with limited range wavelength conversion. It is worth noting that case for full conversion can be usefull for any circuit switched network without additional constraints (i.e. wavelength continuity constraint in WDM), for example telephone network. Toolbox contains also scripts for defining network structures (random networks, user defined networks) and traffic matrixes. Three graph algorithms for shortest path computation are also in this toolbox (they are used for traffic matrix creation).

This article discusses some issues that a typical Windows C++ programmer will encounter when approaching Symbian OS for the first time. Our experience in developing for three successive versions of Symbian OS has given us considerable perspective on what can be difficult when working in this otherwise rich and stable environment. While one reason for Symbian s success may be the desire of many mobile phone manufacturers not to be tied to Microsoft, the other reason is that Symbian has put together a lightweight, elegant system that succeeds in providing a very impressive range of functionality. Here are some pointers to help ease the transition to successful Symbian OS application development.

The Pages 2.0 specification is one of the most exciting Java Community Process releases of the year. Chances are you picked this book to learn more about the new features of 2.0. Or you may be interested in using for the first time in your next project. Regardless of your interest, we ve put together a book that tries to bring you up to speed fast. The goal of has been to make it easier to create sophisticated, well-designed Web applications. We feel that the authors of the specification have achieved their goal. Working with databases or XML has never been simpler. Your applications can be functionally well-organized. You can create your own reusable components.

This book is intended for RF planners, to serve as a practical tool in their daily work designing indoor radio distribution systems. Based on feedback from readers of the first edition it was clear to me that I needed to add more material and in depth description of the basics of indoor systems based on using repeaters; this has grown into a new Section 4.7. There was also a strong demand to add more detail and dedicate a full chapter to radio planning in tunnels, for both rail and road tunnels; and redundancy principles in the design focus for solving the challenge of handover zones. An entire Chapter 11 is now dedicated to tunnel radio planning.

The explosion in demand for wireless services experienced over the past 20 years has put significant pressure on system designers to increase the capacity of the systems being deployed. While the spectral resource is very scarce and practically exhausted, the biggest possibilities are predicted to be in the areas of spectral reuse by unlicensed users or in exploiting the spatial dimension of the wireless channels. The former approach is now under intense development and is known as the cogni- tive radio approach (Haykin 2005).

Over many years, RF-MEMS have been a hot topic in research at the technology and device level. In particular, various kinds of mechanical Si-MEMS resonators and piezoelectric BAW (bulk acoustic wave) resonators have been developed. The BAW technology has made its way to commercial products for passive RF filters, in particular for duplexers in RF transceiver front ends for cellular communica- tions. Beyond their use in filters, micromachined resonators can also be used in conjunction with active devices in innovative circuits and architectures.
