NAME

       RTIMULibCal - Calibration tool for the Sense HAT IMU

SYNOPSIS

       RTIMULibCal [filename]

DESCRIPTION

       RTIMULibCal  is a command line calibration tool for the Raspberry Pi Sense HAT IMU. It has
       no command line options, but does provide an interactive interface through which  the  IMU
       can be calibrated. It is essential to calibrate the IMU's magnetometer (at the very least)
       or else poor results will be obtained when querying the device's orientation (or “pose”).

       The calibration data obtained from this tool will be output to filename which defaults  to
       “RTIMULib.ini” if omitted.

       When  started, a menu will be presented providing options to calibrate the magnetometer or
       the accelerometer within the IMU (or select “x” to exit):

              Options are:

                m - calibrate magnetometer with min/max
                e - calibrate magnetometer with ellipsoid (do min/max first)
                a - calibrate accelerometers
                x - exit

       Given that calibration typically  requires  that  the  HAT  is  rotated  through  numerous
       orientations, it is recommended to perform this on a Raspberry Pi with a minimum number of
       cables attached to it. For instance, you may wish to set up WiFi connectivity, and operate
       the  calibration  application  over  an SSH connection so that you can remove keyboard and
       monitor cables from the Pi, leaving just the power cable necessary.

       Please note that the magnetometer ellipsoid calibration option (“e”) requires  GNU  Octave
       to be installed.
