Abstract

According to the fact that embedded system needs have the function of USB host in practical application but most microprocessing chip usually has not,a scheme has been put forward to the system based on S3C44B0X and SL811HST.This system use core board of ARM7 and expand board of USB as the way of hardware's method ;write USB driver and load it under ucLinux system.This system has the advantages of low cost and stable operation.It can be used in handheld devices and fieldwork occasions.
