[Paparazzi-devel] BMP085 no Message

[Christoph Niemann]

Hi community,

I'm trying to get my BMP085 barometer to work. I added the following to my airframe:

  <firmware name="fixedwing">
    <target name="ap" board="tiny_1.1">
    [...]
      <define name="USE_I2C0"/>
      <define name="BMP_I2C_DEV" value="i2c0"/>
      <define name="SENSOR_SYNC_SEND"/>
    [...]
    </target>
    [... ]
    <subsystem name="i2c"/>
  </firmware>
  <modules>
    <load name="baro_bmp.xml"/>
  </modules>

But there are no Messages from the Baro. I tried the I2C and connected an ETS Airspeed Sensor, wich was working. 
I tried to check the signals but my scope sucks :-( . The bit of the Signal i saw looked  at least like i2c.  I connected the breakout-board like this:

baro      tiny

SDA ---- SDA0
SCL ----  SCL0
VCC---- 3.3V
GND---- GND

Is this correct, or did I make a mistake? (Pull-up or something?)
Currently, I don't know where to look for the error.

Thanks in advance

Christoph
