[Paparazzi-devel] airspeed sensor

Hello, I have an Eagle Tree sensor and I’m trying to get the measured values in the message airspeed without activating the airspeed control chain. I have moved now to the new “firmware” definitions and have in the airframe file:


<firmware name="fixedwing">

    <target name="sim"                                   board="pc" />

    <target name="ap"                                     board="tiny_2.11">

      <param name="FLASH_MODE"                           value="IAP" />

      <define name="AGR_CLIMB" />

      <define name="LOITER_TRIM" />

      <define name="ALT_KALMAN" />

                <define name="USE_I2C0"/>

                <define name="MEASURE_AIRSPEED"/>



<subsystem name="i2c"/>





<load name="airspeed_ets.xml"/>



When I compile I get the warning:

CC /home/autopiloto/paparazzi/var/LASSv2/ap/arch/lpc21/i2c_hw.o

CC /home/autopiloto/paparazzi/var/LASSv2/ap/modules/sensors/airspeed_ets.o

modules/sensors/airspeed_ets.c:47:2: warning: #warning either set USE_AIRSPEED or SENSOR_SYNC_SEND to use ets_airspeed


If I run anyway, the airspeed message is fix: 15


If I activate the flag in the module like this:


<load name="airspeed_ets.xml">

<flag name="SENSOR_SYNC_SEND"/>




I get the next when compiling:

CC /home/autopiloto/paparazzi/var/LASSv2/ap/arch/lpc21/i2c_hw.o

CC /home/autopiloto/paparazzi/var/LASSv2/ap/modules/sensors/airspeed_ets.o

modules/sensors/airspeed_ets.c: In function `airspeed_ets_read_event':

modules/sensors/airspeed_ets.c:164: warning: implicit declaration of function `DOWNLINK_DEVICECheckFreeSpace'



I don’t know if I’m missing something or doing something wrong. Any idea?
