Abstract: By using gateway systems on large 32-bit platforms, networks of small, 8- and 16-bit microcontrollers can be monitored and controlled over the Internet. With embedded Linux, these gateways are easily moved from full-blown host PCs to embedded platforms like the PC104. In this class you will learn about hardware platforms that support embedded Linux, Linux kernel configuration, feature selection, installation, booting and tuning.

基于ecos的redboot，該包支持多種處理器。用戶(hù)可以根據(jù)自己硬件平臺(tái)，通過(guò)ecosconfig來(lái)配置，配置界面和編譯linux kernel差不多。本包已經(jīng)正對(duì)Intel IXP2400平臺(tái)做了相應(yīng)配置，硬件平臺(tái)為雙CUP架構(gòu)。壓縮文件中有更為詳細(xì)的說(shuō)明。

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).

本代碼為編碼開(kāi)關(guān)代碼，編碼開(kāi)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(kāi) 關(guān)）等類(lèi)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(kāi)關(guān)為5個(gè)引腳的，其中2個(gè)引腳為按下 轉(zhuǎn)輪開(kāi)關(guān)（也就相當(dāng)于鼠標(biāo)中鍵）。另外3個(gè)引腳用來(lái) 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(kāi)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(shuō)明問(wèn)題，下面是以一段流水 燈來(lái)演示。
