The laser scanning USB2.0 Interface System

Laser scanning transmission to the control section, Figure 4 for the communications test the experimental results. Set in the application of which CY7C68013 in SLEFIFO mode,[link widoczny dla zalogowanych], and data transmission through the blocks of communication. Preliminary experiments showed that the system transfer rate can be stable at 27MB / s, can fully meet the laser scanning machine interface system design requirements. Currently, the laser scanning machine interface system next time the system of ongoing reliability testing. Figure 4 Communication Test results Figure4ExperimentalresultsofcommunicationtestingUSB There are 4 data transfer mode laser scanning Fapai system needs to send large amounts of data at high speed, so the conclusion in the design of four block transfer mode is selected, the use of endpoint EP2, block transfer, 512Byte / {g,[link widoczny dla zalogowanych], 4 times the output buffer, auto output, 16-bit mode in the high-speed data transmission systems, the use of PCI bus, the high work. Control information and limit information indicating speed in real time through the end of transmission and the advantages of collecting data storage, although there are 332 College of section 19 of the data effectively to solve real-time transmission and processing; but through the use of USB bus interface technology, not only to solve the data transmission and processing of real-time problem, and USB bus-based real-time data communication system can be freely attached to the various types of PC, which to a large extent, improve the portability of data communications equipment and versatility. With the popularization of USB bus, USB bus transfer methods based on laser scanning data transmission system with the traditional laser Fapai systems,[link widoczny dla zalogowanych], faster, cheaper, more versatile system to improve the product competitiveness, has considerable practical value, while in the field of high-speed data transmission also has a wide range of application. 【References [1] Ye Hongxun.
