Design Of Electronic Music Score Reader Based On Embedded System

Electronic music score reader designed to bring convenience to performer, it can turn the music-score automatically, not only the players can maintain a good pace of playing, but also can turn the music sheet automatically. It’s very ideal for music-lovers to learn and use. This system designed to replace the traditional paper-based sheet, it’s based on the TQ S3C2440board as the hardware platform, embedded Linux operating system and Qt4graphical user interface as the software platform, design an electronic music score reader which can turn the music spectrum automatically, and user-friendly interfaces. The main contributions of this thesis are as follows.1. Through the research of embedded system design method and market demand analysis of the electronic score reader, this thesis presents the general design scheme of the system.2. According to the analysis of the micro processor selection and combined with the abundant peripheral interface modules of S3C2440, give the global design of the hardware structure, including the touchscreen module design and LCD display module design.3. After analyzing the Linux operating system, the thesis gives the development process of transplantation of operating system, including boootloader custom, kernel transplantation, root file system transplantation, finally transplant the application program to the board successfully.4. Through the analysis of driver model of Linux, the configuration of kernel, the compilation of the code, the system realize the LCD driver transplantation, touch screen driver transplantation, as well as audio driver transplantation based on S3C2440.5. Using the Qt4graphical user interface tools to design the application, achieved a lot of functions, such as play music, music score display, music-score turning automatically, modify the music sheet.Finally, transplant application to arm platform successfully. According to the display result of interface, summarizes the deficiency of the system, and describes the prospect of the electronic score reader system.
