So I have an UNO(3) and I decided to go on the cheap and try out a camera. All of my research over the last few days is not giving me a whole lot on this specific shield. I have no problem getting the Serial to show me that it has ‘taken a picture’.
I either cannot see the picture on the SD car(Windows 8.1) after they are taken or I am getting the first few top bars. Is saving to the SD Card(Kens Cl4 - 8gb) the issue?
I have tried:
SdFat lib
JPEG extension for saving to card
Have NOT tested the camera by itself yet
Here is the card
