I made a large graph PNG, to show the result of doing a segmented data acquisition and then averaging the 1891 (-> max, when 14K samples) frames.
No more 255 levels of resolution
For a single temp dataset of my experiment I need two channels, which can be related by their timestamp.
But not taking the same time in each channel, because I will do some more averaging (But now using more the e-res approach) and will need to interpolate.
Because my traces will always be climbing (I'll choose the correct timings for that) this is easy and reliable. From start to finish, I'll group those values that have a minimal of 0.05V between the start of the group and its ending. Then I'll create a single point for each group which time is in the middle and it's value is an average of all the values.
This way I know for sure my curve will always rise and that there's enough vertical distance to have a reliable slope.
