Topic: Can't communicate with Adafruit VC0706 camera (Read 55 times) previous topic - next topic

I've got an Arduino Uno and two Adafruit VC0706 cameras.  I've been following the tutorial and have gotten the cameras partially working.

I am able to get a working video signal from the analog out, and I've gotten the cameras to work with the provided CommTool.  However, I cannot get the camera library and sample code to recognize the camera.  cam.begin() always gives the message "No camera found?".  So I went into the library code and added some extra print statements to see where it is failing, and I have discovered that it is timing out because I am not receiving any data.

I'm pretty new to Arduinos, so is there something basic I am forgetting?  The only modification I made to the sample code was commenting out all of the sections that reference the SD card; I do not have that hooked up yet, I'm trying to get some sort of camera response first.  I thought it could be a baud rate problem, but CommTool works perfectly at the default 38400 baud.

Any ideas?  Thanks in advance!

Figured out the problem.  Of course it was something stupid; One of my resistors was the wrong value, so all the camera responses were going straight to ground.   :smiley-sweat:
