Abstract

To control peripheral unit USB Host must be realized in embeded system.This paper puts forward a 32 bit MPU+RTOS for realizing USB Host.To use ISP1160 as USB main controller and AT91R40008 in which μC/OS-Ⅱ is transplanted as microcomputer.It is given a way to realize the embedded USB Host through the design of hardwares and softwares.This technics makes the embedded system connect USB peripheral unit,enlarge function,enhance flexibility of use.
