| Abstract: | In USB 2.0 interface circuit, 2 resistances is adopted to match impedance, and built-in IC CY7C68013 is used as on/off circuit of USB device. Firmware program is red in RAM when power-up operation. The design of USB bus and functions drivers was adopted in design of USB driver. USB firmware program was compiled with C51 language, the program supplied separately by the developers of operating system and device. |
