thanks, so change the 1023 to 100, or even smaller, up to you
so 790pix * 3sec = 39.5 minutes memory
if you would make lines ( last point to new point ) and a skip of n pix between the samples
the show might be much better, but that short memory is reduced even more…
i not go into details, but usually data are stored to array, condensed to averages and saved to historic data file ( ok , next class )
