ArduCam OV7670 Shield V2 SD Problems

Help & Support Robot Parts

Hi,

I bought the ArduCam arduino shield and am trying to use the OV7670 camera with it.

Of the example code that ArduCam provides, the only script that seems to work with the OV7670 camera is ArduCAM_Shield_V2_Digital_Camera. This code is supposed to take a picture and save it to an SD card, but I keep getting an SD card error when I use the card reader on the shield. I have reformatted the card and am assuming the pinouts are correct because there is only one way the shield and arduino fit together.

Can anyone tell me what the problem might be? Or another way to save the data or stream the data to my laptop?

Thanks,
J

Thanks! It turns out the memory of the SD card can’t exceed 8G on the arduino uno platform, and I was using a 16GB card. That fixed the problem.

This would’ve been my next try since it seems like ArduCam used a voltage divider rather than level shifter to supply the SD card with 3.3V. Looks like the person in the github post is bypassing one of the resistors and supplying 5V.
