hi, I did same question one month ago and had a good response from xevel http://forum.wiibrew.org/read.php?11,41113 Yesterday I released first version of my software with full source code: http://wiibrew.org/wiki/3DMaze Please, keep in mind that Motion Plus gives you angular velocity around Wiimote own axes... You can compute orientation with it only if you know "previous" orientation!by michelinux - Coding
Sorry matthewbauer, your answer has nothing to do with my question :) Actually I understood that: I must calibrate Motion Plus somehow calibrated rx is angolar velocity towards bottom of wiimote calibrated ry is anticlockwise roll angolar velocity calibrated rz is horizontal anticlockwise angolar velocity yaw decreases if: calibrated rz * gforce.z > 0 or calibrated rx * gforce.by michelinux - Coding
ok, I can read rx, ry and rz from Motion Plus... but how to use them? I see big numbers (about 8000) but I'don't know exactly what they represents (angular velocity?) and what unit of measure is used. My main goal is to calculate yaw value when IR data are not valid... how can I do it?by michelinux - Coding
