@IOTrav, one method is to calculate a simple CRC for your stored values. Take a look at this topic for inspiration:

Best way to store preference in flash?

Hi Guys, I am currently being a basic device that controls some LED lights, with this I am looking to store some basic variables so they are persistent For example INT max_brightness = 80; INT ambient_limit = 15; INT mode = 3; What is the simpliest method that also makes it easy to modify and retrieve the variables? Ideally it would be useful to be able to define default entries should the variable not exist in flash etc? Thanks
