OV7670 with FIFO

The OV7670 has a FIFO module, which is a module with buffer storage space for slow MCUs that can achieve image acquisition control. This module adds a FIFO (first in, first out) memory chip, which also includes a 30w pixel CMOS image sensor chip, a 3.6mm focal length lens and lens mount, and various power supplies required for the onboard CMOS chip. The chip's data file), the board also leads to the control pin and data pin for easy operation and use.

Control Description:

Because the FIFO is used as the data buffer, the data acquisition is very simple, the user only needs to care about how to read it, and does not need to care about how the specific data is collected, so that the control and timing relationship of the CMOS can be reduced or not even concerned. It is possible to achieve image acquisition.

The control timing is as follows:
