【摘要】：作為信息技術(shù)的核心，互聯(lián)網(wǎng)技術(shù)正在不斷的從傳統(tǒng)的PC平臺(tái)向各種移動(dòng)智能終端遷移。作為移動(dòng)互聯(lián)網(wǎng)主要的終端平臺(tái)之一，智能手機(jī)以其高性能和強(qiáng)大的計(jì)算處理能力逐漸占據(jù)著越來越大的移動(dòng)終端市場(chǎng)。因此，有關(guān)智能手機(jī)的各項(xiàng)技術(shù)也成為了各大企業(yè)和科研機(jī)構(gòu)研究的熱點(diǎn)。作為能大幅增強(qiáng)智能手機(jī)用戶體驗(yàn)的技術(shù)之一，觸摸屏技術(shù)一直是各大手機(jī)制造商關(guān)注的焦點(diǎn)之一，電容觸摸屏已經(jīng)在智能手機(jī)中得到廣泛的使用，因此智能手機(jī)系統(tǒng)中觸摸屏模塊的驅(qū)動(dòng)程序開發(fā)與設(shè)計(jì)就成為了一項(xiàng)不可或缺的重要工作。 本文在介紹了觸摸屏的發(fā)展趨勢(shì)及其在智能手機(jī)中的應(yīng)用之后，詳細(xì)分析了目前廣泛使用的觸摸屏驅(qū)動(dòng)程序開發(fā)模式（我們暫且稱之為傳統(tǒng)開發(fā)模式）中存在的問題和不足，即由于硬件依賴性而缺乏平臺(tái)通用性。針對(duì)這種問題和不足，從問題的根源出發(fā)，提出了一種全新的觸摸屏驅(qū)動(dòng)開發(fā)模式，并詳細(xì)設(shè)計(jì)了其具體的實(shí)現(xiàn)流程。然后選用展訊sc8810芯片平臺(tái)，，基于內(nèi)嵌的TPC觸摸屏控制器，依照新模式對(duì)觸摸屏驅(qū)動(dòng)程序進(jìn)行了設(shè)計(jì)。對(duì)比傳統(tǒng)開發(fā)模式，新模式對(duì)驅(qū)動(dòng)程序做到了代碼與數(shù)據(jù)分離，由于驅(qū)動(dòng)代碼和配置項(xiàng)數(shù)據(jù)相分離，驅(qū)動(dòng)代碼具有硬件通用性，配置項(xiàng)數(shù)據(jù)可以靈活配置，當(dāng)觸摸屏設(shè)備型號(hào)發(fā)生變化時(shí)，驅(qū)動(dòng)程序開發(fā)人員只需要按照當(dāng)前設(shè)備參數(shù)修改配置項(xiàng)數(shù)據(jù)，就可以完成驅(qū)動(dòng)開發(fā)，無需因?yàn)樵O(shè)備型號(hào)的變化，重新編譯代碼或者全編譯整個(gè)工程，為驅(qū)動(dòng)程序的開發(fā)工作帶來了便利。另外，如果將多種不同型號(hào)的觸摸屏配置數(shù)據(jù)集成在一起，驅(qū)動(dòng)代碼就會(huì)具有自適應(yīng)功能，從而可以實(shí)現(xiàn)跨平臺(tái)工作，具有很好的平臺(tái)通用性，達(dá)到了預(yù)期的效果。 論文還做了一下兩個(gè)方面的研究：1、深入研究觸摸屏的工作原理；2、對(duì)Linux設(shè)備驅(qū)動(dòng)有關(guān)的核心理論進(jìn)行了研究。
[Abstract]:As the core of information technology, Internet technology is constantly migrating from the traditional PC platform to various mobile intelligent terminals. As one of the main terminal platforms of the mobile Internet, the smart phone has gradually occupied more and more large mobile terminal market with its high performance and powerful computing ability. Therefore, the smart phone technology has become a hot spot in the research of enterprises and scientific research institutions. As one of the technologies that can greatly enhance the smartphone user experience, touch-screen technology has been one of the focus of attention of the major mobile phone manufacturers, capacitive touch screen has been widely used in smart phones. Therefore, the development and design of touch screen module driver in smart phone system has become an indispensable and important work. After introducing the development trend of touch screen and its application in smart phone, this paper analyzes in detail the problems and shortcomings in the widely used touch screen driver development mode (we call it the traditional development mode). That is, lack of platform versatility due to hardware dependence. In order to solve this problem, a new touch-screen driver development mode is proposed from the root of the problem, and its realization flow is designed in detail. Then, based on the embedded sc8810 touch screen controller, the touch screen driver is designed according to the new mode. Compared with the traditional development mode, the new mode can separate the driver from the data. Because of the separation of the driver code and the configuration item data, the driver code has the hardware generality, and the configuration item data can be configured flexibly. When the touch-screen device model changes, the driver developer can complete the driver development only by modifying the configuration item data according to the current device parameters. Recompile the code or compile the whole project to facilitate the development of the driver. In addition, if we integrate different types of touch screen configuration data together, the driver code will have adaptive function, which can work across platforms and have good platform versatility and achieve the desired results. This paper also makes two aspects of research: 1, deeply studies the working principle of touch screen, and studies the core theory of Linux device driver.
