Andrew Tridgell ce3fb290f1 AP_Airspeed: fixed initialisation of auto-calibration 2013-08-30 13:01:34 +10:00
Andrew Tridgell c6c59174b3 AP_Airspeed: return when airspeed init fails 2013-08-30 13:01:33 +10:00
Andrew Tridgell 31e1b7fcf6 AP_Airspeed: list MEAS airspeed in ARSPD_PIN docs 2013-08-30 13:01:33 +10:00
Andrew Tridgell 893d2da6f6 AP_Airspeed: added auto-calibration support 
This uses a Kalman filter to calculate the right ARSPD_RATIO at runtime

Andrew Tridgell 68adeb041d AP_Airspeed: support ARSPD_PIN option for choosing source 
this gives us support for arbitrary analog pins for the airspeed
sensor, plus support for the EagleTree airspeed driver on PX4

Andrew Tridgell dfb98490f4 AP_Airspeed: use rationmetric analog input for airspeed sensor 2013-05-13 15:13:19 +10:00
Andrew Tridgell 00e905b025 AP_Airspeed: use new voltage_average() API in Airspeed driver 2013-03-08 10:01:15 +11:00
James Bielman 5631f865b2 Update floating point calculations to use floats instead of doubles. 
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.

Pat Hickey 7017a35fc3 AP_Airspeed: fix for AnalogIn read_average 2012-12-20 14:51:35 +11:00
Pat Hickey dfc8e91fd3 AP_Airspeed: port to AP_HAL 2012-12-20 14:51:25 +11:00
Andrew Tridgell 0c864fd4dc AP_Airspeed: a bit more filtering 
this helps reduce noise at low speed

Andrew Tridgell 47be6d8ad1 AP_Airspeed: remove airspeed filter and run at 10Hz 
this saves on the filter memory, and gives just as good a result

Andrew Tridgell dcc50b5705 AP_Airspeed: removed values passed to constructor 2012-08-08 16:38:39 +10:00
Andrew Tridgell 518d6365ff AP_Param: update remaining libraries for new constructor syntax 2012-08-08 12:11:57 +10:00
Michael Oborne 9e4d118fdb Airspeed Library - fix param names. 
The Group definition give the start of the param name.
This way we can maintain multiple instances if required of the same library as options.

Andrew Tridgell feb456de56 Airspeed: Added AP_Airspeed sensor library 
this will allow an airspeed sensor object to be passed to AHRS for
dead reckoning
