Andrew Tridgell eea7758a63 AP_Baro: added GND_EXT_BUS option 
this is needed to enable probing for a MS5611 on external I2C bus. The
MS5611 looks the same as a MS5525 airspeed sensor, so we can't just
auto-probe. Users will need to enable external barometers

Andrew Tridgell f2246326bb AP_Baro: added MS5611 probing, and support 3 baros on Pixhawk2 
this adds sensor probing for barometers, simplifies the MS5611 driver,
and adds support for the I2C external barometers on Pixhawk2

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers 
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Andrew Tridgell 0b71652afc AP_Baro; allow for exact replay of baro data 2016-05-07 18:27:20 +10:00
Andrew Tridgell 8a987bf67d AP_Baro: removed filtering of baro data in HIL/SITL 
this was just causing lag in replay and doesn't actually help in SITL
 2016-05-07 18:27:18 +10:00
Tom Pittenger f435c5ee50 AP_Baro: tolerate GND_ALT_OFFSET step inputs 
large inputs make the EKF angry, this will allow the param update to slew over a few seconds

Lucas De Marchi 81a298c9c8 AP_Baro: reduce header scope 
We don't need to expose to other libraries how each backend is
implemented. AP_Baro.h is the main header, included by other libraries.

Instead of including each backend in the main header, move them to where
they are needed. Additionally standardize the order and how we include
the headers.

The advantages are:
	- Internals of each backend is not exposed outside of the
	  library
	- Faster incremental builds since we don't need to recompile
	  whoever includes AP_Baro.h because a backend changed

Andrew Tridgell 840c9e65bb AP_Baro: don't notify the GCS of new pressure reference too often 2015-11-09 14:34:07 +11:00
wsilva32 da9118fbd0 AP_Baro: average SITL baro measurements using update() 2015-10-21 10:25:08 +11:00
Lucas De Marchi 4d3229daa2 AP_Baro: remove check for HAL_CPU_CLASS 
We don't support HAL_CPU_CLASS <= HAL_CPU_CLASS_16 anymore. This makes
BARO_MAX_INSTANCES and BARO_MAX_DRIVERS constant for all supported
boards.

Andrew Tridgell a5462fec0b AP_Baro: allow selection of primary barometer and add 3rd baro 
this is useful for external I2C barometers on a PH2
 2015-09-14 14:27:41 +10:00
Tom Pittenger 749c0c190f AP_Baro - fix BARO_ALT_OFFSET param 
This param seems to have been un-implemented. This is putting it back in. Adds a meter offset to the calculated altitude form the baro sensors.
Also changes it from int8 to float

Gustavo Jose de Sousa f18802bc46 AP_Baro: standardize inclusion of libaries headers 
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Randy Mackay ddda0d52ce Baro: reorder declaration to fix compiler warning 
No functional change
 2014-12-11 13:06:24 +09:00
Andrew Tridgell d404cc6542 AP_Baro: add set_external_temperature() 
this allows the use of an external temperature sensor for calibration
purposes, such as the sensor built in to the digital airspeed sensor.

The main affect this has is on the EAS2TAS calculation

The get_calibration_temperature() is used to choose either an external
temperature or an internal one. If an internal one is used then it is
clamped at no higher than 25 degrees C, to prevent hot electronics
on startup affecting altitude scaling and EAS2TAS

used for automatic barometric adjustment by a ground station equipped
with a barometer
 2013-07-10 14:38:57 +10:00
Paul Riseborough 7bdb098e77 AP_Baro: added get_EAS2TAS() 
this provides the scaling factor between equivalent and true airspeed
based on altitude
 2013-07-04 16:56:56 +10:00
Andrew Tridgell 2d089174cd AP_Baro: rename AP_Baro_BMP085_HIL to AP_Baro_HIL 
there is nothing specific to the BMP085 in it
 2013-05-02 15:08:42 +10:00
Andrew Tridgell 8ceabc97f1 AP_Baro: added accumulate() function 
this allows us to read the BMP085 much faster
 2013-01-09 23:05:17 +11:00

uncrustify fa90f0b80f uncrustify libraries/AP_Baro/AP_Baro.h 2012-08-21 19:00:51 -07:00
Andrew Tridgell a7b9aff79f AP_Baro: the DerivativeFilter now handles duplicate data 
this saves a few bytes of memory
 2012-08-08 12:07:36 +10:00
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.
 2012-07-06 15:11:30 +10:00
Andrew Tridgell 209136386b AP_Baro: added get_pressure_samples() interface 
this returns how many samples were used to calculate the last pressure
 2012-07-05 16:29:21 +10:00
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
 2012-06-27 16:01:50 +10:00
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
 2012-06-27 16:01:50 +10:00
Andrew Tridgell 7ba744a11a I2C: convert barometer library to new I2C library 
this also adds a healthy attribute and error checking
 2011-12-28 20:41:53 +11:00
Pat Hickey d026e48032 AP_Baro : Add init( AP_PeriodicProcess * ) method to interface & implementations 
AP_Baro_MS5611 and AP_Baro_BMP085 implement the interface, with stubs only

Pat Hickey d113992c10 AP_Baro: Create virtual interface 2011-12-11 15:21:09 -08:00
Pat Hickey cc6837cbab AP_Baro: Export AP_Baro_BMP085 and AP_Baro_BMP085_HIL headers. 2011-12-11 15:21:09 -08:00
Pat Hickey 9250053bfe Added AP_Baro and AP_Baro_MS5611 classes. 
Incomplete and does not work.
