| Abstract: | This paper introduces a based on the ARM7 core processor developed USB host system. Implementation of a U disk data read and writes another U disk function. System hardware design has the advantages of low cost, small power consumption, speed etc.. In the software, the system completed the USB host controller driver, the core driver and user software design, well completion equipment enumeration, configuration and other functions; the system supports Mass Storage protocol, and the establishment of a FAT simplified file system, can complete the U disk file read, so that the application of USB detachment the personal computer has universal significance. Research of USB system are summarized, and the embedded USB host development prospects |
