Airspeed on APM 2.5 - not working after Arduplane 2.60 #755

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Any arduplane firmware after 2.60 (2.61,2.62,2.63) fails to display airspeed 
properly on OSD , over USB or over telemetry in mission planner. The airspeed 
appears to be there, but is not influenced by the sensor.

The really "funny" part, is that the airspeed data is good as ever in any 
firmware, in terminal's "test airspeed"  !  

Isn't that really, and impressively fishy ?   It scares the sh*t out of me, 
what other data may be only seen in some parts of code in APM 2.5 ?

I am not completely sure about the other hardware, but somebody wrote that 
airspeed is ON on APM 1.4 - som all I can say is that it does not work on APM 
2.5.

I know what the problem is now:

I am flying with ARSPD_ENABLE=1  - enabling sensor, my ARSPD_USE=0  because I 
did not wish the AP to use airspeed.

Before 2.60 - is ARSPD_ENABLE=1 , then airspeed is displayed in telemetry.

after 2.60 ARSPD_USE must be 1 , to display it in telemetry stream.

Please correct it, so AS is properly displayed even if ARSPD_USE=0
