Hello,
I know that this is old, but I was wondering if you could provide some simple sample code on how to use your library. For example, connect to the camera and take a picture.
I am working at an Arduino program to control cameras to take photos (part of a larger project). I implemented different methods so far, such as IR, BTle (for phones), and web based requests for Panasonic and Olympus cameras. I'd like to add generic ptp commands, but it's a bit of a hassle to find good info on it in a centralized manner. If you provide some sample code and maybe a bit of documentation I can port the library to Arduino.

Thanks!
