MPU9150 flight


After a flimsy hot gluing of the board in place, the MPU9150 took its 1st 2 batteries of flying. Results were drastically improved over having the board under the battery. There's still a bit of error because the board isn't perfectly flat, but it manages to recover. The current or the flexing of having it under the battery was the problem.

There was 1 source file for the MPU9150 on http://permalink.gmane.org/gmane.linux.kernel.iio/4339, revealing undocumented register REG_YGOFFS_TC. He never uploaded the header files.

With the full Marcy 3 software & the crystal, the MPU9150 only reads at 80Hz.

9150 quad


I too am building a small QUAD with 9150 and BMP085!

Had good luck getting 9 axis data, only took an hour or so.... must have been lucky, you seem to have needed more time :-(

What software is doing the IMU and flight control?

Richard.
