Andrew Tridgell 0f72401d8d AP_Baro: added GND_ALT_OFFSET parameter
used for automatic barometric adjustment by a ground station equipped
with a barometer

Paul Riseborough 7bdb098e77 AP_Baro: added get_EAS2TAS()
this provides the scaling factor between equivalent and true airspeed
based on altitude

Andrew Tridgell 61361dac9b AP_Baro: added units to baro documentation 2013-07-04 16:56:56 +10:00
Paul Riseborough 3b98bbd159 AP_Baro: more precise altitude calculation on PX4
if not using an AVR CPU then use a more computationally expensive
altitude calculation, which is more precise at higher altitudes

Randy Mackay aa2b10f044 AP_Baro: TEMP parameter comment fix 2013-06-18 11:28:36 +09:00
James Bielman 4fa7bb1486 Add AVR compatibility header for missing math.h definitions.
- Define float versions of math functions to the double versions
  on AVR (eg. #define sinf sin).
- These macros appear to be missing in older versions of avr-libs.
- Include AP_Math.h rather than math.h to get these definitions.

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.

Andrew Tridgell 518d6365ff AP_Param: update remaining libraries for new constructor syntax 2012-08-08 12:11:57 +10:00
Andrew Tridgell a7b9aff79f AP_Baro: the DerivativeFilter now handles duplicate data
this saves a few bytes of memory

Andrew Tridgell f501503eb0 AP_Baro: improved barometer averaging
this changes the barometer calculations to floating point. On a MS5611
this is actually about twice as fast as the previous 64 bit
calculations, but gains us more accuracy as we are able to take
advantage of sub-bit precision when we average over 8 samples.

Andrew Tridgell 185c6e5b32 AP_Baro: change to a 7 point DerivativeFilter for climb rate 2012-07-05 13:00:47 +10:00
Andrew Tridgell f9fc7aafe7 AP_Baro: use DerivativeFilter in barometer climb rate 2012-07-05 13:00:46 +10:00
Andrew Tridgell 5bccfbd94c Barometer: fixed airstart for APM
we need to re-load the ground pressure and temperature from eeprom on
and airstart

Andrew Tridgell c387edd74c Baro: added get_altitude() and get_climb_rate() interfaces
this allows the barometer driver to calibrate and return altitude and
climb rate values. This will be used by the AHRS drift correction code
for vertical velocity

The climb rate uses a 5 point average filter
