【摘要】：电子乐谱阅读器可以帮助演奏者自动翻谱,保障演奏者良好的演奏节奏,而且还能根据播放的进度自动跳转翻谱,非常适合乐谱爱好者学习时使用。本设计以代替传统的纸质乐谱为目的,以天嵌S3C2440开发板为硬件平台,以嵌入式Linux操作系统和Qt图形界面工具作为软件平台,实现了一个便携的、操作界面人性化的、能自动翻谱的电子乐谱阅读器。主要工作如下： 1.通过对嵌入式系统的研究,结合对目前市场上的电子读谱器的功能分析,提出了更为合理的设计需求。 2.综合分析了微处理器的选型,并基于S3C2440微处理器及其外围接口,给出了硬件的总体设计,并完成了触摸屏模块和LCD显示模块等硬件模块的设计。 3.通过对Linux操作系统的深入分析,给出了操作系统移植的开发流程,包括Bootloader定制,内核移植,根文件系统的移植,最后将设计的程序成功移植到开发板上 4.通过对Linux下驱动模型的认识和解析,以及对内核的配置和代码的编译,实现了基于S3C2440的LCD驱动移植,触摸屏驱动移植以及音频驱动移植。 5.利用Qt图形界面工具进行应用程序的设计,实现了音乐播放,乐谱显示,自动翻谱,乐谱修改等模块的功能。 最后将程序移植到ARM平台,根据所显示的界面效果,总结分析了本系统的不足之处,并对电子读谱器的未来研究方向做了展望。
[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.
