1  Using Arduino / Sensors / Re: a module that can receive and transmit at the same time? on: July 06, 2013, 08:22:30 pm
Hi Guys,
You may take a look at this project http://www.arducam.com
They use 115200bps to transfer video http://www.arducam.com/arducam-bluetooth-module-wireless-image-system/
If you can port it to 2Mbps with NRF24L01+, I think it will be much fast than now achieved.

Hi again:
You need a extra LCD display the video you are capturing, right?
There are a lot of 2.8" or 3.2" LCD module which can accept camera data with RGB565 format.
But you need to connect the LCD to the camera module by yourself like the way the ArduCAM shield does. They have already intergrate the LCD and Camera modules together.

Hi,

by the way is there any screen that i can get image on wireless from the OV cam ? a screen that will be in the place of the laptop
You can try the windows software http://www.arducam.com/downloads/ArduCAM_BT_JPG_115200.exe, which can display the JPEG image stream on your laptop. You can test this software by sending binary jpg file data via serial port.

Hi Guys,
Why use OV7670, it outputs uncompressed image, that is really to large for Arduino to handle.
You can try other image sensors from Omnivision like OV2640, OV3640 ,OV5642 which can output compressed JPEG image. And the output data is really small than OV7670.
You can take a look at OV5642 camera module sample pictures from http://www.arducam.com/camera-modules/5mp-ov5642/

Hi mike_one,
It is almost impossible to caputre image from OV7670 directly with Mega2560.
The data stream from OV7670 is 24MHz, it exceeds the maxim IO toggling speed of the MCU.
So you may need extra hardware like ArduCAM shiled to buffer the entire image before read them out with fairly low speed.
You may have interest to know how to capture compressed JPEG image from ArduCAM shield with Mega2560, please view here: http://www.arducam.com/arducam-bluetooth-module-wireless-image-system/.

Hi Mazman,
You can use Mega2560 board to start your project, it has rich resources include PWM channels to control your motors and GSM modules.
For the camera capture part, I recomend you to use Arduino based camera like Arducam http://www.arducam.com.
You can find demonstration using Mega2560 + OV2640 camera modules transfer images wirelessly http://www.arducam.com/arducam-bluetooth-module-wireless-image-system/

Hi Guys,
It is possible to capture the pictures with Arduino boards with CMOS camera modules like OV7670 or something like that.
But OV7670 output uncompressed image which is too large for Arduino boards to handle in 1 second.
As far as I know, there are some image sensor from Omnivision like OV2640, OV3640 or OV5642 which can output compressed JPEG image stream.
The image data is far less than uncompressed one, you can acheive 1fps with these modules, you can find interesting project like ArduCAM arduino based camera http://www.arducam.com.  And wireless image transfer demonstration http://www.arducam.com/arducam-bluetooth-module-wireless-image-system/

You can find tutorials for interfacing OV7670 or similar camera modules from Arduino based camera  http://www.arducam.com/tutorial/
But I recommend to use OV2640 module which can output JPEG image, which is easy to handle the compressed image data by Arduino boards.

To use ov5642 module,you can got 1080p JPEG with Arducam shield. If you need the code, please leave me an email address.

Hi msingh,
Here is a website for interfacing CMOS camera modules with Arduino.
www.arducam.com
I looked into their opensource library, they use the Arduino hardware I2C and Wire library to configurate camera registers. It maybe useful for you to configurate your camera module.
They also give out a tutorial which transfer the image wirelessly with bluetooth, you can find it here:
http://www.arducam.com/arducam-bluetooth-module-wireless-image-system/
Hope these will help you.
Regards

Hi RandallR,
This is exactly what you are needed.

It seems that they have add support for MT9D111 camera module, Great! smiley

13  Using Arduino / Displays / Arduino based open source camera LCD ArduCAM shield questons on: September 29, 2012, 06:20:28 am
Hi everyone,
I just find a Arduino based open source camera shield from www.arducam.com
My questions is that will this ArduCAM shield fit for my object recognition project? My project needs to recognize a invade event and trigger the alarm.
Thanks in advance.
