The Design of USB Interface for Large-format Plotter

摘要

Plotter interface system is responsible for receiving commands and datum from host computer and then transferring them to print-control-system. On the basis of protocol of USB and principle of large- format plotter, a newly-designed plotter interface system, which takes high speed USB chip, CY7C68013, as its core, is recommended in this paper. The structure of CY7C68013 is introduced, and how to work of plotter interface system and how to transfer datum through USB is explained in particular in the paper.
