摘要
针对目前部分播放器播放文件单一的缺陷,采用TI公司的Cortex-M3系列的微控制器LM3S9B96为核心,设计多功能的音频播放器,用来实现*.mp3、*.wma、*.wav等不同的格式文件的播放。软件系统由支持嵌入式的实时多任务的操作系统μC/OS-II以及图形化界面设计软件μC/GUI和Fat Fs文件系统组成,人机交互可通过触摸屏实现,系统具有播放流畅、易操作等特点。
The multi-function audio player of TI＇s Cortex-M3 LM3S9B96 microcontroller as control core is designed against current part player playing file single defect, be used to play ＊. mp3, ＊. wma, ＊.way files of different formats. It＇s soft system is made of support for embedded real-time multi-tasking operating system μC / OS-Ⅱ,graphical interface design software μC/ GUI and FatFs file systems, the human-computer interaction can be achieved through the touch screen, the system has play smooth, easy operation and other characteristics.
