Sorry for being very new to programming

Try downloading just the gyro code form Kevin and see if it works.
Look at the user_routines.c in the PURE gyro code.

i did that and i didn't get reasonable values
because i move the sensor 90 degrees and back where he was and i don't get the same values which i get i n the start

I havent tried yet but I think the sensor gives you the change not the actual value.

Remember that the gyro has a maximum turn rate that it can report. Turning faster than that (which is easy to do when holding the gyro in your hand) will cause signal overflows which translate into lower rotations report than actually occurred.

Try doing your test and turning the gyro VVVVEEEEERRRRRYYYYY SSSSSSLLLLLLLOOOOOOWWWWWWLLLLLLYYYYY and see what happens.
