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.
