lsm9ds1 IMU get tilt along specified axis returns error: ...'__imuS' undeclared (first use)

Howdy,

Looks like the built code for this LSM9DS1 sensor includes an undeclared variable, '__imuS ' when compiling with BlocklyProp. It gives an error when trying to use the LSM9DS1 IMU's: "gets tilt along specified axis" command...

    }

  • Okay - it's a typo - it should be generating "__imuZ", so know that I know what to fix, I'll get it entered. The fix will appear in Demo early in the week, but it will be a few weeks before we push another update to the BETA/production servers.

    Thanks,
