Hi,
I'm trying to use Sparkfun's IMU-9250 breakout board to record the azimuth heading on one of my wheeled robots, and I'm having some trouble getting believable yaw data from the device. Using just the unmodified SPARKFUN_IMU sketch, I recorded the Yaw data output while slowly rotating the IMU in a more-or-less horizontal plane. When I plotted the data in Excel, I got the following plot
I can sorta squint and think that there is a linear progression of yaw values, but there is so much noise that I hesitate to call this anything but garbage. Am I doing something wrong here?
TIA,
Frank
