I have decided to go for a periodical download of photos over USB and your ultimate.lua. For the moment I will be exploiting the "bug" that ptpcamgui has so I can stop the script remotely. I'm aware this is not a clean method but I've tested it many times now and it hasn't crashed anything yet.
Hi, sorry I am new to CHDK. I've downloaded ptpCamGui and have it working with me PowerShot A2200.
My goal is to take time laps photos over an indefinite period, downloading them to the computer once an hour. It sounds like you are trying to do something similar? Have you had any luck? Could you walk me through the steps?
Also, I seem to be getting an error in ptpCamGui when I press the download button: "It is an error encountered!" (presumably a bad German translation)
The console shows this:
>> luar get_mode() << script:10
10:ret:false (Length: 23)
>> luar require("lptpgui").dcimdl(false)
