Andrew Tridgell d79386d574 AP_Baro: use GND_EXT_BUS to allow a specific bus to be probed 2018-09-07 08:36:02 +10:00
Andrew Tridgell dda8e7c35a AP_Baro: probe both i2c buses on CubeBlack for barometers 2018-09-07 08:36:02 +10:00
Randy Mackay af6e2d2c8c AP_Baro: add PROBE_EXT param values 
this makes it easier for users to select the external baro they want to use on GCSs that do not display the bitmasks

Siddharth Purohit 5ef5537371 AP_Baro: move Baro UAVCAN subscribers and handlers to AP_Baro_UAVCAN 2018-08-29 22:54:59 +01:00
Andrew Tridgell 3fd25ad548 AP_Baro: added HAL_BARO_ALLOW_INIT_NO_BARO 2018-08-23 13:29:59 +10:00
Andrew Tridgell 1439b1a730 AP_Baro: added option to probe any i2c baro using GND_PROBE_EXT 
This adds a hwdef.dat define HAL_PROBE_EXTERNAL_I2C_BAROS. When set,
we get a new parameter GND_PROBE_EXT that is a bitmask of i2c
barometers to look for.

This allows boards that have no builtin baro to work without
rebuilding

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

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers

Lucas De Marchi 929348ff75 AP_Baro: MS5611: always use timer thread 
Remove support to run MS5611 on main thread since we shouldn't be doing
I2C transactions there and we are moving to "thread per bus"
nonetheless.

Tom Pittenger d55050e5e3 AP_Baro: slow down the LPF for slewing to a new GND_ALT_OFFSET 
Instead of a couple seconds, make it about 15sec. This makes TECS happy by not glitching the height demand as much. When applied too fast the TECS height demand causes a large single oscillation as it chases the filter lag.

Lucas De Marchi f1ade970a3 AP_Baro: MS5611: Use AP_HAL::Device abstraction

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

Lucas De Marchi 8eef58a8c2 AP_Baro: remove check for AVR CPUs 
Remove the checks for HAL_CPU_CLASS > HAL_CPU_CLASS_16 and
HAL_CPU_CLASS >= HAL_CPU_CLASS_75. Corresponding dead code will be
removed on separate commits.
 2015-11-04 12:14:14 +11:00
Lucas De Marchi 831d8acca5 Remove use of PROGMEM 
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:

    git grep -l -z PROGMEM | xargs -0 sed -i 's/ PROGMEM / /g'
    git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'

The 2 commands were done so we don't leave behind spurious spaces.

AVR-specific places were not changed.
 2015-10-30 14:35:16 +09:00
Lucas De Marchi 2c38e31c93 Remove use of PSTR 
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.

This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.

AVR-specific places were not changed.

Tom Pittenger 749c0c190f AP_Baro - fix BARO_ALT_OFFSET param

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.

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

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.
 2013-01-16 13:52:17 +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.

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
 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
