温馨提示
1.拍下后请联系客服获取资料
2.带FIFO的摄像头比不带的多了个3M的缓存,可将采集的数据暂存在这个缓存中,使用时读取缓存中的图像数据即可,因此可减少对单片机采集图像数据时对MCU速度的要求。(例程以RGB565方式存放图像数据)
 
1.产品概述
OV7670带FIFO模块,是针对慢速的MCU能够实现图像采集控制推出的带有缓冲存储空间的一种模块。这种模块增加了一个FIFO(先进先出)存储芯片,同样包含30w像素的CMOS图像感光芯片,3.6mm焦距的镜头和镜头座,板载CMOS芯片所需要的各种不同电源(电源要求详见芯片的数据文件),板子同时引出控制管脚和数据管脚,方便操作和使用。
 
2.管脚定义
3V3:输入电源电压(推荐使用3.3,5V也可,但不推荐)
GDN:接地点
SIO_C:SCCB接口的控制时钟(注意:部分低级单片机需要上拉控制,和       I2C接口类似)
SIO_D:SCCB接口的串行数据输入(出)端(注意:部分低级单片机需要       上拉控制,和I2C接口类似)
VSYNC:帧同步信号(输出信号)
HREF:行同步信号(输出信号,一般可以不适用,特殊情况使用)
D0-D7:数据端口(输出信号)
RESTE:复位端口(正常使用拉高)
PWDN:功耗选择模式(正常使用拉低)
STROBE:拍照闪光控制端口(正常使用可以不需要)
FIFO_RCK:FIFO内存读取时钟控制端
FIFO_WR_CTR:FIFO写控制端(1为允许CMOS写入到FIFO,0为禁止)
FIFO_OE:FIFO关断控制
FIFO_WRST:FIFO写指针复位端
FIFO_RRST:FIFO读指针复位端
 
3.控制说明
由于采用了FIFO 做为数据缓冲,数据采集大大简便,用户只需要关心是如何读取即可,不需要关心具体数据是如何采集到的,这样可减小甚至不用关心CMOS的控制以及时序关系,就能够实现图像的采集。
控制时序如下:
