代码说明：

  这是我自己写的一个摄像头数据存储SD卡程序，quartus的verilog编写，摄像头采用自己添加的外设接口，数据采用dma采集，SD用的是软件自带的SPI内核以及znFAT的文件系统。帧率我没有测，有兴趣的可以测测，初学者可以参考学习，写的代码有点乱，如果有不懂的可以和联系。(This is what I wrote it myself a camera, SD card data storage program, quartus the verilog write, add their own camera with peripheral interfaces, data acquisition using dma, SD with the software that comes with SPI znFAT kernel and file system. I did not measure the frame rate, are interested can Cece, beginners can refer to the study, wrote the code a bit messy, if there do not understand can contact)
