hi, anyone can help me ? when i would like to write in my sd card, the program display me an error. (sorry for my english i'm french)

This program work's :

Please help me, i have a big project tommorrow ...
Thank's for read my post !

Of course the second program works. It just doesn't produce the results that you want. What it does and what you want you kept to yourself, though, so we can't help you.

What happens when you run this program ?

You have to take the GPS outside, or near a very large window, and wait between 20 seconds and 20 minutes for it to start up.
