If you're writing data to a file in the Edison, when you lose power your data will still be there when you power it back up. The only data you'll lose is anything you've collected but have not saved it to the file when the power goes out.
From our test that has not been the case. I am going to try to compile the files on the edison.
To what path are you saving the files?
I'm working on a project and I have to read a lot of sensor values.
I want to save that data in a file but don't know how to get started...
Perhaps you can help me by giving me some helpfull links/ example code/...
Thanks in advance!
