[Paparazzi-devel] adding a telemetry message

[Refik Sever]

Hello,

I am trying to add a telemetry message. I followed the commands in the wiki:

1. I added this line to default_fixedwing_imu.xml file:

<?xml version="1.0"?>
<!DOCTYPE telemetry SYSTEM "telemetry.dtd">
<telemetry>
  <process name="Ap">
    <mode name="default">
      <message name="AIRSPEED"            period="1"/>
      <message name="ALIVE"               period="5"/>
      <message name="GPS"                 period="0.25"/>
      <message name="NAVIGATION"          period="1."/>
      <message name="IVMEOLCER"           period="0.2"/>

2. I added these lines to ap_downlink.h file:

#define PERIODIC_SEND_IVMEOLCER(_trans, _dev) Downlink({ \
    struct FloatEulers* att = stateGetNedToBodyEulers_f(); \
    DOWNLINK_SEND_IVMEOLCER(_trans, _dev, &(att->phi), &(att->psi), &(att->theta)); \
})

3. I added these lines to messages.xml file:

 <message name="IVMEOLCER" id="5">
     <field name="phi"   type="float" unit="rad" alt_unit="deg"/>
     <field name="psi"   type="float" unit="rad" alt_unit="deg"/>
     <field name="theta" type="float" unit="rad" alt_unit="deg"/>
   </message>

However, while building it gives this error:

firmwares/fixedwing/main_ap.c:410:5: warning: implicit declaration of function 'DOWNLINK_SEND_IVMEOLCER' [-Wimplicit-function-declaration]
firmwares/fixedwing/main_ap.c:410:5: warning: nested extern declaration of 'DOWNLINK_SEND_IVMEOLCER' [-Wnested-externs]

Please help about this error.
