| Abstract: | The design of a reading and writing controller for the USB bus is based on CPLD as a master chip.Udisk can connect to the PC’s USB port using this controller,which works for the real-time monitoring and analysing of the USB bus data,and automatically disables the PC outputting it’s files data to the U-disk,while the PC does not affect the U-disk’ s normal file reading. |
