IMPORTANT! You have to download Java version 1.8. The rxtx library doesn’t support newer Java versions.
This is a follow-up to “Arduino OV7670 live image to screen” video. In this tutorial I am connecting only a camera to Arduino (no screen) and sending image to computer over serial connection.
Image can be transferred with up to 2Mbit/sec baud rate. Although that speed is not very stable and I have set 1Mbit/sec as default.
Interestingly tough the 1Mbit/sec only works with Arduino clones. With Genuine Arduino Uno you have to lower the baud rate since 1Mbit/sec is always very glitchy. I think that for some reason Chinese ch340 serial chip handles high speeds better than FTDI chip used in the original Arduino.

Wiring part starts at 5:04
can use C program language?
Amazing project! But.. atmega328p has terrible Serial speed, data must be passed through USB converter what really, but really slows it down. I will recomend atmega16u2 or atmega32u4 to everyone trying this project (they have internal USB controller), they can be found on Arduino Leonardo or Pro Mirco boards. Their Serial performance is much better 🙂
It keeps saying that the it couldnt find my MainWindow class from the ArduinoImageCapture-master- module
Hey! I have a question.
I did a PCB with this and everything was working fine, and I was watcing the streaming in the Java screen. But then, I plugged another arduino to see some data in the COM of the new arduino and the Arducam stopped sending images. And now, I plug the arduino nando with the arducam and it does not connect, it aways appears a red rectangle. Any suggestion?
hi,
can I get your mail, since i would like todiscuss few things about this interfacing as it looks famaliar to what i am planning to do in my project??
Hey Indrek, I have been trying to run the MainClass on my Raspberry Pi 3, initially the code would not compile, hence I had to download a different .so file library for the ARM architecture. However, the problem is on the last part of the solution, I do not get any ports when I click the drop down menu, and upon clicking "listen", all I get is "null not found". I did read through the code but since I have never used Java, I do not know what part of the code to alter to make sure that getName() receives the port from the Arduino side. The arduino is connected to /dev/ttyAM0 on the Raspberry Pi. Can you please help out? I have been trying for the past week to get this running. Thanks in advance!
To change Java version to 1.8
Download JDK kit8: https://www.oracle.com/java/technologies/javase-jdk8-downloads.html

Hi thx for the tutorial! After I uploaded the code to arduino, I got a blinking RX instead of TX. I didn't see a green square at the midway check point but I was able to get glitchy images that are completely unreadble. Any suggestions?
eror code IDE :
In file included from Adafruit_ST7735_mod.cpp:24:0:
Adafruit_ST7735_mod.h:34:26: fatal error: Adafruit_GFX.h: No such file or directory

what happening about this ?
The image window is opening up, I assigned the correct port and baud rate, but it is not rendering the red rectangle. What could be the issue(I am using Arduino Nano)
Hello , i am wondering if you can help me with a problem. I made the wiring and the program , the frame on java is starting but the problem is that nothing appear on the frame , not green or red display , nothing .
If you know anything about this , let me know .
Thank you ^^
Man… This project saves me a lot of work! I was wondering… would it be possible to replace the USB connection with a RF transmitter with receiver having a Rs 232 to usb converter ? I am looking to have the whole thing wireless….Do you think it would work?
I'd be happy for just a red square…
after run getting error written like this-(in intelliJ)
Error: Could not find or load main class C:Usersc01DownloadsArduinoImageCapture-masterArduinoImageCapture-masterlibrxtx-2.2pre2-binswin64rxtxSerial.dll
Sir i am getting a corrupted red rectangle at 3:49 some black lines coming at the end of the red rectangle
Please help me, when I clicked listen button the window just disappeared. An error .log file appeared in scr in the left. I don't know how to fix this one although I tried many times. The error say:

Sir can the video monitored live?
everytime i try to upload the code to Arduino, i get an error message that says

CAN YOU HELP ME PLEASE
Hello,
On trying to take images using ov7670 on my arduino uno I have downloaded codes and necessary libraries from the GitHub. Based on the tutorial I have followed I arranged my files as required. On compiling the code however I have got an error message that I can't fix it. Because I'm doing it for my project and I'm running out of time, I kindly ask a quicker help.
here is the error message:
'class CameraOV7670' has no member named 'waitForPixelClockRisingEdge'
hello where can I found the arduino code…its not in the description video.
there are some errors in the program how to fix that.any suggestion?
Where i can get arduino code?
where is the code?( which file)
i cant find out it in github?
Can I use this camera to process images for “ Object Recognition “ ?
( ` )( ` ) Your OV7670 doesn't have capability to send anything to your PC! it is your Arduino which can do that!
Sir, can the image be sent through the Bluetooth module HC-05 ??
