Camera Not Found?

Post by JonaDC »

Hi everyone,
I'm trying to take a snapshot with the camera and save the image with the SD Breakout Board. The program recognise the board, but i don't know why it doesn't recognise the camera, it always says "camera not found?", and i don`t know what the problem is. Everything is connected on its due place, I use the snapshot model provided on Adafruit's Github. It happens the same with the VC0706 Comm Tool.

I've attached the image of the circuit which i use and the program on a textfile, the circuit it's the same as the one used on the homepage, with the difference that I use an Arduino Uno instead of the Duemilanove.

Post a photo showing the connections for your hardware please. We know the one in the photo works, so it doesn't give us any useful information about the problem. 800x600 images usually work best.

Hi Mike, sorry for the lateness.
I attach two pictures in different views. I hope you can see the connections clearly.
Thanks.

Try moving your GND connection over to the hole in line with the 5v, RX, and TX pins.

IIRC, that board has some non-obvious connections.

Hi Mike,
I did what you told me and is not working yet. It's all connected on its right place, I've checked all with the multimeter so I don't know why it's not working.

Your other connections look good, so we'll have to call this one a dead camera.

How long have you had the camera?

I'm afraid that's well past our 30-day return/replace window.

Thanks for your help Mike but, are you really sure that the camera is dead? I mean, is there any option to test it?. Just to be totally sure.

If you have a display that can take NTSC/PAL input, like an old disc player, you can try hooking up that output from the camera board and seeing if it produces video that way.

Hi Mike,
I know its been a while since the last time we spoke, sorry for the lateness. I did what you told me and the output of the video is working, so I guess that the camera is not dead yet, right? What's the problem then?

Apparently the camera and its NTSC/PAL output system are good, but the Serial output system is dead.

Hi Mike,
I've had the chance to check with an oscilloscope the serial system pins of the camera. As you can see in the photos, the camera receives the pulse sequence and immediately sends back a train pulse. Ive checked directly in the pin of the ATMEGA and it receives this signal, so what's then the problem? Could it be incompatibility with the operative system or maybe the software it's not correctly configured?

Try connecting the camera to pins 0 and 1 and using the Arduino as a pass-through converter for the CommTool that's linked from the tutorial. See if you can get it to respond that way.
