摘要
介绍以CPLD控制为核心的CMOS图像采集系统,系统选用彩色图像传感器OV7620,并通过USB接口以类似DMA方式进行快速的图像传输。最后给出了单片机固件程序和设备驱动程序的实现方法。
A CMOS image collecting system under the control of CPLD was introduced. System used color image sensor OV7620 and image was transferred in DMA simulation mode through USB interface. The programming method of MCU firmware and device driving was given.
