【摘要】：電子樂(lè)譜閱讀器可以幫助演奏者自動(dòng)翻譜,保障演奏者良好的演奏節(jié)奏,而且還能根據(jù)播放的進(jìn)度自動(dòng)跳轉(zhuǎn)翻譜,非常適合樂(lè)譜愛(ài)好者學(xué)習(xí)時(shí)使用。本設(shè)計(jì)以代替?zhèn)鹘y(tǒng)的紙質(zhì)樂(lè)譜為目的,以天嵌S3C2440開(kāi)發(fā)板為硬件平臺(tái),以嵌入式Linux操作系統(tǒng)和Qt圖形界面工具作為軟件平臺(tái),實(shí)現(xiàn)了一個(gè)便攜的、操作界面人性化的、能自動(dòng)翻譜的電子樂(lè)譜閱讀器。主要工作如下： 1.通過(guò)對(duì)嵌入式系統(tǒng)的研究,結(jié)合對(duì)目前市場(chǎng)上的電子讀譜器的功能分析,提出了更為合理的設(shè)計(jì)需求。 2.綜合分析了微處理器的選型,并基于S3C2440微處理器及其外圍接口,給出了硬件的總體設(shè)計(jì),并完成了觸摸屏模塊和LCD顯示模塊等硬件模塊的設(shè)計(jì)。 3.通過(guò)對(duì)Linux操作系統(tǒng)的深入分析,給出了操作系統(tǒng)移植的開(kāi)發(fā)流程,包括Bootloader定制,內(nèi)核移植,根文件系統(tǒng)的移植,最后將設(shè)計(jì)的程序成功移植到開(kāi)發(fā)板上 4.通過(guò)對(duì)Linux下驅(qū)動(dòng)模型的認(rèn)識(shí)和解析,以及對(duì)內(nèi)核的配置和代碼的編譯,實(shí)現(xiàn)了基于S3C2440的LCD驅(qū)動(dòng)移植,觸摸屏驅(qū)動(dòng)移植以及音頻驅(qū)動(dòng)移植。 5.利用Qt圖形界面工具進(jìn)行應(yīng)用程序的設(shè)計(jì),實(shí)現(xiàn)了音樂(lè)播放,樂(lè)譜顯示,自動(dòng)翻譜,樂(lè)譜修改等模塊的功能。 最后將程序移植到ARM平臺(tái),根據(jù)所顯示的界面效果,總結(jié)分析了本系統(tǒng)的不足之處,并對(duì)電子讀譜器的未來(lái)研究方向做了展望。
[Abstract]:Electronic music reader can help players to turn over the music automatically, ensure the player's good playing rhythm, and also can automatically jump over the music according to the progress of play, which is very suitable for music lovers to learn to use. The purpose of this design is to replace the traditional paper music score, to take the sky embedded S3C2440 development board as the hardware platform, to take the embedded Linux operating system and the QT graphical interface tool as the software platform, to realize a portable and humanized operation interface. An electronic music reader that automatically flips music. The main work is as follows: 1. Based on the research of embedded system and the analysis of the function of electronic spectrum reader in the market at present, a more reasonable design requirement is put forward. 2. The selection of microprocessor is analyzed synthetically. Based on S3C2440 microprocessor and its peripheral interface, the overall design of hardware is given, and the hardware modules such as touch screen module and LCD display module are designed. 3. Through the in-depth analysis of Linux operating system, the development process of operating system transplantation is given, including bootloader customization, kernel transplantation and root file system transplantation. Finally, the designed program is successfully transplanted to the development board. Through understanding and analyzing the driver model under Linux and compiling the kernel configuration and code, LCD driver porting, touch screen driver porting and audio driver porting based on S3C2440 are realized. 5. The QT graphical interface tool is used to design the application program, and the functions of music playing, music score display, automatic music flipping, music score modification and so on are realized. Finally, the program is transplanted to arm platform. According to the interface effect, the shortcomings of the system are summarized and analyzed, and the future research direction of electronic spectrum reader is prospected.
