How to extract Magnetic data independently? #9

Hi All!

Recently I'm using 3DM-GX3-25 IMU on the Husky robot and got the rostopic /imu/data. However, what I need is only the Magnetic data measured by the IMU.

I checked on my Husky robot and found that it used the driver microstrain_3dmgx2_imu. Then I checked the ros-drivers and it seems that gyroscope data, accelerometer data and magnetic data are fused and output together as /imu/data.

So I'm wondering is there any way to modify the driver to only extract the Magnetic data (output as a rostopic like /imu/magnetic)? Any advice or hint is appreciated.

Thanks! @chadrockey @mmwise @kwc @gerkey
