摘要
基于嵌入式Linux技术,提出一种智能无线多媒体数字播放系统的设计方案。介绍了系统功能、总体结构、主控CPU和无线模块。通过Linux系统中SPI接口的驱动对无线模块的控制,成功实现了区域位置自动识别和音视频文件的受控播放以及与用户进行交互的图形化界面操作程序。
A design scheme on intelligent wireless multimedia digital explanation system based on embedded Linux is proposed. Generally, system function ,architecture,controlling CPU and wireless module are introduced. The wireless handset decides which area it belongs to and chooses the corresponding video file to play automatically, utilizing the SPI driver based on Linux operation system control on the wireless transceiver chip CYWUSB6934. Finally, the operating program which running on graphical user interface platform is implemented as well.
