OV7670 problem

Other Hardware General Electronics
1

Hello, I have OV7670 camera module (1), Arduino uno R3 boards, and SD card reader (2)(without 3.3v-5v level shifter). As I see this SD card module is bad !!!(3)
8GB class4 FAT32 sd card
Also I have 2pcs EEPROM module(4) if it's possible to use for camera!

I want to use Camera,
So I need any way, how to use this camera module with eeprom or without it, or how to use this sd card module with resistors or some other parts.

Please give me some links or wiring pictures !

That's outputing 30fps 640x480 digital VGA video. So not easily, no, as that's >18MB/s

3

So what I must do?
As I saw, that camera has minimal fps and resolution.
Do I need better controller for video?

or another task: can I take only picture (not video) without sd card?

You have a video camera, you need video hardware. The Arduino is not that.
Perhaps you need something more like this:

How can I use this MD80? it has micro usb port, so do I need something like micro usb to arduino module, or it's just for PC use?

The point is video is way way beyond the capbilities of a small microcontroller with 2k of RAM.

Other than recording video what are you trying to achieve?

First goal is just video streaming with camera->arduino->PC or take picture
Second is face detection or something like this.
Third and MAIN goal is video streaming via wifi or camera->arduino->wifi transmit to cloud server-> access from PC or phone or tablet or server

As MarkT said, you won't be able to do this with an arduino.

IMO, a raspberry Pi would be a better choice for these tasks

thanks :slight_smile:

You need a webcam and OpenCV on the PC then...

You can run OpenCV on the Raspberry Pi, but you'll want a model 2 for faster
performance and you can only use the Ras Pi camera module (or a webcam).

PC will be much faster running OpenCV
