Beginning Arduino ov7670 Camera Development

This is exactly the kind of information needed to manage the engineering complexity of connecting a highly controllable camera to your Arduino card and be successful in taking pictures. This book opens up the world of inexpensive digital video recording to the average experimenter. Be warned, the book is full of technical detail and circuit requirements in order for this combination of devices to work. So be prepared for a tour de force in getting the first prototype to work on your bench. The author does a top notch job of delivering the right information to the experimenter to manage this complex subject.The book covers the pinouts and features of this particular camera( SD memory included ). It covers the nature of the camera's conversion of visual light into digital data and the effects of contrast selection and internal filter use. There are a number of background pdf files to support the subject listed on the internet and and extensive appendix to support experimental variations that the reader would like to explore.There are a few issues that are not discussed in the book that the reader should know about. First, he specific camera model discussed in the book is not generally available and the OV7670 FIFO model must be specifically ordered. Otherwise, you may get the wrong device to work with the book's information even if the pinout is the same. I found 13 different cameras not of this type on the first two pages of Amazon using a search for "Arduino camera". The second issue is pin connectivity. The camera module has 18 pins and an Arduino UNO only has 10 digital and a few power pins for use. So, an UNO or Leonardo will not work for all possible combinations. A Mega or DUE should be intended in the mind of the experimenter. The third issue is performance. The UNO and Leonardo have a 16 MHz clock witch is too slow for camera use unless the camera has the integrated FIFO buffer. Even so, these small Arduinos have very little memory and the program size from the book can overwhelm the limited memory available. That is why I am doing all of my Arduino camera prototyping on a DUE. And extra cycles will be needed to interact remotely with an Arduino camera device which once again supports the need for the 85 MHz clock of the DUE. Good experimenting.

Very good practical book, saved me a lot of time. If anyone needs microcontroller + camera project I highly recommend this book.

Want to connect a camera to a MicroController? This is the place to start. the Arduino code ran on my Mega2650. Since most of the code is straight C, it shows how to control the camera and interface to your MCU.

This is a detailed description of the hardware making up the OV7670 camera with several code examples; without these examples I would have been scratching my head and surfing the internet for hours trying to make heads or tails of what was going on.I would go so far as to say this is the essential book for this highly specialised piece of equipment - if you have an Arduino and want to interface this camera then you NEED this book to avoid frustration.Easy to read, many tips along the way, lots of technical "background" information that you can skip if you want to but which I found very interesting - there's nothing to dislike about it. Well done Robert Chin.

This book starts real well with a very basic introduction to Arduinos, the OV7670 and electronics, but after 80 pages it degenerates into a double spaced annotated code listing.

There are only two chapters useful : End of Chapte 4 and Chapter 6 Part 2. The rest is basical explanation how Arduino IDE, Mega and Uno board and else are running.Too many pages of screenshots.And NO explanation in what format the raw data is stored ( *.YUV ) files stored in SD card.To see a picture you have to take a picture, save it in and SD, took the SD to a PC, run an external programm ( old DOS black screen command) and later you get a *.PNG.Comment : the proper orientation of the OV7670 is like Book Cover - see mi picture tilt -

It is good book for learning interfacing digital camera. Digital camera thoroughly explained, which makes interfacing task easy.

Ohne dieses Buch hätte ich es wohl nie geschafft, mit der ov6760 Photos zu schießen und auf den Arduino zu übertragen.
