STM32F407-OV7725

注意:

1.stm32f407正点原子探索者开发板dcmi接口采集不带fifo的ov7725摄像头/直接显示在lcd或者存储在数组中
2.A8脚分频系统时钟给xclk,stm32提供时钟xclk给ov7725
3.

DCMI_DMA_Init((u32)img,160*120,DMA_MemoryDataSize_HalfWord,DMA_MemoryInc_Enable);//DCMI DMA配置 
DCMI_DMA_Init((u32)&LCD->LCD_RAM,1,DMA_MemoryDataSize_HalfWord,DMA_MemoryInc_Disable);//DCMI DMA配置  

上一句是图像存储在img数组中,下一句是直接显示在lcd上
4.采集分辨率为120*160 考虑到stm32f4的ram大小
5.注意文档的编码
6.使用并参考修改了正点原子以及野火的代码
7.如果存储于数组中再显示,会比较卡
