I need a freelancer to create an arduino function which is based on the Arduino PTP_2.0 library ([url removed, login to view]). The sketch would be a combination of PTPObjHandles and PTPObjInfo and would scan through the digital camera's memory to obtain the last filename in memory, it would then return this filename through the function.
The objective is to call this function at the start of a capture setting to record in an XML file the start picture filename, and at the end to record the end picture filename. If you can do a simple demo of the function, so it stores the filename (and the image number) in variables it would be appreciated so I can increment from a starting point.
e.g. the function scans the camera, and works out the last image is [url removed, login to view], it records this in a variable (e.g. CamFileName), and also stores the number 4044 in CamFileNumber, then if I take two images, I can increment the cam number +2 to know what the latest image number should be, and at the end I can call the function again to get the last CamFileName, and the CamFileNumber.
Hopefully this is a simple project, so if you can keep the bids low it would be appreciated since it is for a personal project, not commercial.
