摘要
探索了一种在低成本下实现线阵CCD输出信号快速采集以及与PC通信的方法。讨论了线阵CCD系统的整体结构及工作流程。采用VHDL语言编写了驱动程序,实现了CCD的正确工作。利用DSP实现了对下位CCD的控制,在控制程序中利用"乒乓原理"实现了线阵CCD的数据采集,并同时给PC快速上传数据。基于Visual C++6.0平台编写了PC机控制软件,实现了对硬件电路的控制和对CCD输出信号的分析处理。
A rapid data acquisition for linear CCD output signal and the communication with PC under low-cost condition is studied.Based on the discussion of the overall CCD system structure,the driving program is accomplished with VHDL language,and the correct CCD output signal is achieved.DSP chip is adopted to control the slave CCD,and the 'Ping Pong' principle is used to carry out data acquisition and uploading at the same time.The PC control software programmed with Visual C++6.0 platform can control the slave CCD and accomplish output signal analysis and processing correctly.
