基于USB2.O的线阵CCD数据采集系统驱动电路设计

摘要

The driver circuit for linear CCD data acquisition system was designed based on USB2.0. The system's overall design concept and the realization of drive circuit were focused on. Complex programmable logic device (CPLD) was used as core, and rich interface signals were provided for users with the help of programmable technology. The experimental result indicates that the driver circuit meets the design requirements and has certain practicability.%设计基于USB2.0的线阵CCD数据采集系统的驱动电路，重点介绍系统的整体设计思路和驱动电路的实现。以复杂可编程逻辑器件(CPLD)为核心，充分发挥其“可编程”的技术特性。实验结果表明：该电路符合设计要求，具有很强的实用性。
