Re: [Paparazzi-devel] 'IMU_MAG_X_SENS' undeclared when using NPS

[Felix Ruess]

Hi Joseph,

in that case you can just add

<define name="IMU_MAG_X_SENS" value="1"/>
<define name="IMU_MAG_Y_SENS" value="1"/>
<define name="IMU_MAG_Z_SENS" value="1"/>

to your airframe file (in order to satisfy the mag simulation).

Also I would recommend to update to v5.8 ;-)

Cheers, Felix

Hello all,

I use version v5.4.2_stable-3-gc8d866b-dirty and my board is UmarimLite 2.

I am trying to compile NPS and I have added the following to my airframe file:

<target name="nps"   board="pc">

      <subsystem name="fdm" type="jsbsim"/>

    </target>

  <section name="SIMULATOR" prefix="NPS_">

    <define name="JSBSIM_MODEL" value="&quot;Malolo1&quot;"/>

    <define name="JSBSIM_LAUNCHSPEED" value="20"/>

    <define name="COMMANDS_NB" value="3"/>

    <define name="ACTUATOR_NAMES" value="{&quot;throttle-cmd-norm&quot;, &quot;aileron-cmd-norm&quot;, &quot;elevator-cmd-norm&quot;}"/>

    <define name="SENSORS_PARAMS" value="&quot;nps_sensors_params_invariant.h&quot;"/>

    <define name="JS_AXIS_MODE" value="4"/>

    <define name="BYPASS_AHRS" value="TRUE"/>

  </section>

And I get this error:

/home/cgs/paparazzi/sw/simulator/nps/nps_sensor_mag.c: In function 'nps_sensor_mag_init':

I think it is related to the fact that the Umarim IMU does not have a mag, but I'm not sure how to fix it.

Thanks

Joseph
