[Paparazzi-devel] Eagle Tree Airspeed Sensor Problem

Hello all,

I am trying to put to work the Eagle Tree airspeed sensor on a YAPA2 connected 
to the I2C port as described on the wiki. Every time I turn on the autopilot 
and then power the eagle tree sensor my autopilot freezes (the LEDs on the 
autopilot board stop blinking), I can see that I only get error packages on the 
telemetry link and my Ground Station stops receiving information.

I have connected the sensor as described on the wiki (GND to white, +5V to Red, 
SDA to Yellow and SCL to brown). To power the sensor I connected the Red cable 
to one of the +5V ports used to power the servos and I also tried connecting it 
directly to the 14V battery that I am using to power the YAPA2 with the same 

Anyone has any thoughts?

Best Regards,
