Hi Carlos,

How do you want your data to be stored in the SD card. Do you want it to create a new file every day? Keep updating one file? What tags to do you want to be pulled into the files? Within reason you can setup the files however you want. Here’s some example code of somebody creating a custom historical log. You can save them as a CSV, a text file, or if you’re doing a custom historical log you could potentially save them as other formats if you know how to setup those formats.

This post that Jordan created also shows some code that can be used to write to the SD card.

Have you already formatted the SD card to EXT3?

If you only want certain tags, you can either put them into groups so that you’re only calling the historical logging info from certain groups. Or you can do a custom historical log like the example I gave above.
