Hi, could someone give me an example (or give me a link to one) about how to save data (expecially arrays) in the SD Memory card.
Many thanks. B.R.
"I want to start writing my program"
Before you start writing any program, you need to design your software.
And you need to think about how you will do things like writing data to the SD Cards.
This is an essential part of the programming exercise - you need to learn to do this stuff!
"looking at some examples"
As already noted, there are plenty of examples readily available - easily found with a little googling.
You will, of course, need (at least) basic programming skills to understand the examples...
