The magnetometer is accessed through Linux's industrial I/O (IIO) subsystem as lis2mdl_magn with channels:
- magn_x
- magn_y
- magn_z
- timestamp
For example:
root@tsimx6ul:~# iio_attr -c lis2mdl_magn -c magn_x dev 'lis2mdl_magn', channel 'magn_x' (input), attr 'raw', value '630' dev 'lis2mdl_magn', channel 'magn_x' (input), attr 'scale', value '0.001500' root@tsimx6ul:~# iio_attr -c lis2mdl_magn -c magn_y dev 'lis2mdl_magn', channel 'magn_y' (input), attr 'raw', value '-165' dev 'lis2mdl_magn', channel 'magn_y' (input), attr 'scale', value '0.001500' root@tsimx6ul:~# iio_attr -c lis2mdl_magn -c magn_z dev 'lis2mdl_magn', channel 'magn_z' (input), attr 'raw', value '9' dev 'lis2mdl_magn', channel 'magn_z' (input), attr 'scale', value '0.001500'
This shows a snapshot of the x, y, z values. To get the measured field strength along each axis, multiply the scale by the raw value to get the actual reading in milligauss. In the above example:
- X: 0.945 mG (milligauss)
- Y: -0.2475 mG
- Z: 0.0135 mG
