I have been trying to get a sketch to take a series images from an OV7670 or OV2640 camera and feed them into a photogrametry program. I started with a UNO but found the trickery needed to get around the 3.3v / 5v hurdle when combined with the miserly number of pins available on the UNO too much for me. After struggling too long I bought a DUE - lots of pins 3.3v logic.
Great says I, and I start trying to make some progress only to find it seems the only libraries that say they work on DUE are for blinking LEDs and making noises (an exaggeration but not totally untrue).
To my question - how do I tell what issues need to be confronted before risking damage to the cameras and DUE board.
Just to make things interesting I taught myself K & R C in the late 1980's and could never get around all the vagaries of of C++ and now I'm almost 70 and fighting to hold of what skills I can.
You try and compile the program you have. If it compiles for the DUE then most likley it will work, if you get the pin connections right.
I can't readily think of examples where a program will damage an Arduino or something connected to it, so you just have to get on with it and try.
Its common for libraries not to provide a full list of which Arduinos they work on since the writer of these free libraries would need to buy heaps of different Arduinos for testing ..................
