[Paparazzi-devel] Interfacing to the EagleTree airspeed sensor

[Vassilis V.]

All,

I had a successful flight with the EagleTree airspeed module ( http://www.eagletreesystems.com/Support/manuals/airspeed-v3.pdf 
 ) connected to my TWOG. I did not have to do any hardware  
modifications, the sensor has an I2C interface that I connected  
directly to the TWOG I2C port. I was able to figure out the slave  
address and decode the raw output of the sensor. The results are quite  
good, the module is low cost ($43) and comes with a very good pitot  
tube that includes static and dynamic ports. For now I am simply  
sending the airspeed through the telemetry, the next step would be to  
modify the autopilot code to regulate the throttle in order to keep  
the airspeed constant (and a minimum ground speed). I will do the same  
with the altimeter sensor.

See http://vrhome.net/vassilis for more information, I will publish  
the code as soon as I have the altimeter tested (probably in a week or  
so). Is there any interest on getting this released code released into  
CVS?
