Well thanks for providing it anyway. I could not understand your code as it was rather over my head so I had got most of the way through writing my own when you posted the hack also I was having trouble getting your code to compile from this source, there is no .pde aduino file? I copied and pasted the content of the .ino file into an Arduino sketch but it would not compile. This was about the same time I ran into the same ram problems, I was trying to store arrays of 99 exposures, I cut the arrays back to 50 exposures (enough even for me I'm sure) and is appears to be OK. I have some tweaking to do on the code to finish the V1 then I will post it. I would like to look at your code running to see how you handle dodges, something I have no provision for other than pausing the base exposure. Sorry for being so dim.
