Abstract


USB English called the Universal Serial Bus, an external device interface bus , its biggest advantage is easy to carry and simple connection , since the power supply , USB has excellent versatility , is currently the most mainstream general-purpose peripherals interface. The purpose of this study is to solve the communication problems between the laboratory developed test system with computer , developed and designed USB2.0 data transfer interface , a USB interface , through the improvement of hardware and software debugging practicality and versatility , and successfully used in the data transmission system in a variety of ways , well completion of the transmission system, and the communication between the computers . This article focuses on the following aspects : ( 1) analysis of USB development purposes and Research for the USB feature , and for the USB bus protocol and physical characteristics , such as a specific introduction ; ( 2) based on the subject purpose and direction , the choice of a cypress produced CY7C68013A USB interface data transmission system . Analyzed by online problem may occur for the USB hardware system design and hardware between the host and noted solutions . (3) In accordance with the 68013A different transmission mode and a transmission system , the data format and other factors , the mode classification for different modes of data transfer for the specific hardware and software design , and analyzed for a problem in the specific process and be solve ; After the actual experiment show that the interface compliant with the USB protocol specification and meet the current development of test systems and computer data transmission between the transmission system under a variety of different data formats , and successfully applied for the encounter in the design analyze and solve the problem .
