PaulS:
You are correct that the problem is not in the reading of the data. The data is read from the card correctly. There is no reason to copy it to another array.
Hi Paul, in rereading your comments, I am realizing that I may be missing the big picture. I thought I had to put the data into an array so I could access it later on. My idea was to read the calibration table from the SD card during setup, and then use it with some form of linear interpolation during the main loop. I only want to read the SD card once, no?
Am I missing a best practice for this type of stuff? Learning a lot, that’s for sure.
