OV7670 Camera Module with FIFO Using Featherboard M0This is camera streaming test using Featherboard M0 and OV7670.
It is difficult to stream video using this M0 core, so the camera module actually has FIFO and the MCU is getting the images stored in the FIFO.
OV7670 camera module I am using is has AL422B FIFO behind the camera and you can find the datasheets here and here.
ConnectionMy connection between Featherboard M0 and OV7670 module is listed below.
I2C bus requires the pull-up registers and I have 4.7k-ohm registers to 3.3V on both SDA and SCL.
TestHere is the video of the test code.
As you can see in the video, frame rate is not so fast at this moment (less than 4fps), but it is good enough to use this as small camera project like monitoring system.
