| Abstract: | The method of expanded USB interface of intelligent instrument based on single chip computer is stated. The structure and performance of the USB interface chip SL811HS, hardware circuit of USB interface are introduced, and the design method of the USB interface drivers, structure of the FAT16 file systems are analyzed in detail. The communication between the host computer and USB disk is completed via BULK-IN and BULK-OUT endpoint using SCSI command set. The results of experiment and application show that the scheme features convenient control, fast transmission and reliable storage of data. |
