Abstract:Universal serial bus (USB) Technology is widely applied because of its ease-of-use for peripheral expansion and low-cost to support transfer rates up to 12 Mb/s. Its speed is much faster than that of serial port, and the devices based on USB tie up much fewer hardware I/O address resources than PCI devices do. Due to its characteristics of Plug & Play, USB technology has many advantages and potentials to be applied in data transfer between mobile devices, such as notebooks, which donot allow users to plug their own PCI devices directly in. This paper introduces hardware designs based on the characteristics of USB technology. A general purpose digit I/O control and bulk data transfer module with an AN2131QC chip are implemented, including kernel hardware technology, firmware development, device driver and the applied software development.
Keywords:universal serial bus (USB)  digit I/O control  bulk data transfer
