摘要
基于对嵌入式芯片MCF5329的硬件平台上遵循EHCI标准的USB OTG接口控制器和USB文件系统研究,实现了基于该控制的嵌入式文件系统,经测试实际传输速度达到了10 Mbit/s.对在嵌入式操作系统中如何避免多任务对嵌入式文件和外设造成的思索进行了研究.
This paper researches USB OTG connection controller and the USB filing system based on EHCI standard to the embedded chip MCF5329 hardware platforms.The embedded filing system based on this control is realized,the actual transmission speed has achieved 10 Mbit/s.It is considered how to avoid the influence to multi-duties embedded file and peripheral device conducting in the embedded operating system.
