[Paparazzi-devel] Airspeed_ETS on Lisa/m 2

[Tilman Baumann]

I got a bit pissed off with the airspeed ADC problems (5V ADC values) so 
I just shopped a eagletree module to get something going quick.
But I'm getting plagued by the same kind of issues again. I guess I 
should have done some research before. :)

The Eagletree Airspeed module is VCC +5V (And subsequently the i2c 
levels I suppose)
Lisas i2c(2) port is +3.3 volt though.

Has anyone done this before? Does the ETS module perhaps run on +3.3V? 
Or do I need to buy a level converter? Any tips which chip I should use? 
(nice and small SOIC package with few external parts so I can do dead 
bug style construction on the connector)

Cheers
