Well I need some help here, I just purchased a 9DOF GY85 from dx.com
it took me a long time to get al the i2c adreses to read it on the arduino, send the data to 4v was easier (tnks colorsound!) , but now i have a harder problem,
I want to create a kind of Oculus Rift glases, i already have the cheap sony glasstron and all the hardware connected, the problem here is the math to solve the camera position. I have the Tilt and Roll from the gyros, but i need the Y rotacion, i mean, the magnetic reference.
Check out this video http://www.youtube.com/watch?v=9TGUUd2ZDc0 min 2:10
from the 9 bars, check out the last 3, those are the mag, and the the compass. It super aquare, but there is no linear connection between any of the 3 axes magnetometer data to the compass… so, what is the math involved here ?
i also found that it can be done without magnetrometer data
any idea where to look for this ?
