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 30f631de8f AP_Baro: MS5637: fix CRC check 
The configuration of MS5637 is different from MS5611 in 2 ways:

    - The PROM is of 112 bytes rather than 128
    - The CRC is located in the first MSB of the first word, not the
      last one

For CRC calculation we also need to zero out the last (missing) word.

This renames _check_crc() to _read_prom(), which returns false when the
PROM doesn't contain valid data. It also makes it virtual so MS5637 can
override it. This also moves the PROM read to be all in the same place
rather than split between the CRC field and coefficient fields. Finally
calculate_crc() is renamed to crc4() to be shorter and add info on what
it does.

José Roberto de Souza 7457588d7c AP_Baro: Move initialisation code from MS56XX constructor to init() 
On MS5637 we will need to override the method to read and calculate the
PROM's crc. Thus we need a 2-phase init.

It also makes the constructor of AP_Baro_MS56XX protected since only the
derived classes should instantiate the base one.

Lucas De Marchi 94d01934f7 AP_Baro: MS5611: reduce OSR to 1024 
This is the same change as done in PX4:

	This reduces self-heating of the sensor which reduces the amount
	of altitude change when warming up. Apparently some individual
	sensors are severely affected by this.

	Unfortunately it raises the noise level, but Paul is confident
	it won't be a significant issue.

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.

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.

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.

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.

Caio Marcelo de Oliveira Filho 24178c3e10 AP_Baro: remove unnecessary includes in example 2015-10-21 09:16:10 +11:00
Caio Marcelo de Oliveira Filho ec52df991c build: compile only the HAL files needed by the board 
Instead of requiring every program to specify the HAL related modules,
let the build system do it (in practice everything we compiled depended
on HAL anyway). This allow including only the necessary files in the
compilation.

Caio Marcelo de Oliveira Filho 2e464a53c2 AP_HAL: make code not depend on concrete HAL implementations 
The switching between different AP_HAL was happening by giving different
definitions of AP_HAL_BOARD_DRIVER, and the programs would use it to
instantiate.

A program or library code would have to explicitly include (and depend)
on the concrete implementation of the HAL, even when using it only via
interface.

The proposed change move this dependency to be link time. There is a
AP_HAL::get_HAL() function that is used by the client code. Each
implementation of HAL provides its own definition of this function,
returning the appropriate concrete instance.

Since this replaces the job of AP_HAL_BOARD_DRIVER, the definition was
removed.

The static variables for PX4 and VRBRAIN were named differently to avoid
shadowing the extern symbol 'hal'.

datasheet says.

Julien BERAUD 3b5d73b1fe AP_Baro_MS5611: Fix state machine in case of error 
If there is a read error, reading from the adc will return 0 but moreover,
we need to re-initiate a read or else we are stuck forever.

From MS5611-01BA03 datasheet, p. 10, CONVERSION SEQUENCE:
"After the conversion, using ADC read command the result is clocked out with the MSB first.
If the conversion is not executed before the ADC read command, or the ADC read command is
repeated, it will give 0 as the output result."

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 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 057eb5e6f6 Baro: average over all pressure/temperature samples on MS5611 
this allows us to use the MS5611 barometer at its full 100Hz sample
rate (80Hz for pressure, 20Hz for temperature). The pressure and
temperature values are averaged between reads without adding any
latency. Previously the driver would throw away values between
readings

This also fixes a race condition in reading from the SPI bus that
could lead to bad values from the barometer

rmackay9 01cc5fe938 AP_Baro - removed unnecessary 2 element average filtering of pressure (there is a 4 or 5 element average filter in arducopter code itself, two places is messy) 
- also removed unused _offset_press variable
 2012-03-18 15:18:05 +09:00
rmackay9 7560242721 AP_Baro - added average filter for temperature to replace broken filter

Jason Short e57b91c2e2 Updated on Barometer - increased the Temp filtering and decreased the pressure filtering to and get less temp noise, faster response from pressure. I'm filtering the Climb rate differently now, so this higher pressure noise should not hurt the derivative calcs at all now. 2012-03-06 20:55:35 -08:00
rmackay9 d81c951849 AP_Baro - fixed small compiler warning to do with order of parameters in constructor 2012-02-29 22:46:29 +09:00
justinbeech 62b104cbfa Found free extra 256 bytes of RAM eliminate _clz use from libgcc 
Believe it or not, changing / 2^31 to >>31 saved 256 bytes in the "d" segment.

The reason is that GCC version prior to 4.3.5 does not have a count_leading_zeros (clz) assembler macro, so it uses a 256 byte lookup table called _clz
The _clz table gets pulled in if you do 64 bit division.
This tiny change is the only place that we do long long division.
Changing to a shift saves 256 bytes of ram.

Andrew Tridgell 897d9a1c0b baro: fixed an integer overflow issue at high altitudes 
the averaging array was using 16 bit numbers, but we are storing
numbers with 19 significant bits. That caused overflow at high
altitude, and some very interesting altitude graphs!
