| Abstract: | In order to develop an USB interface for E-Book that is one product of embedded system and then implement communication between the E-Book and PC,the software development includes USB firework program,USB device driver program and USB communication program.On the base of finishing firework program and device driver program, the article introduces the design and implementation of USB communication program detailedly from two aspects,one is I/O interface with USB device driver program,and the other is USB communication on PC.Especially,the article introduces a sample testing program that to test bulk transfer.In the end,the article gives some reasons for error between USB practical transfer value and academic value. |
