Andrew Tridgell 68f8817e97 AP_Baro: removed create() method for objects 
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco

Victor Lambret a4108251e3 AP_Baro: fix get_last_update(instance) 
The method was not using the instance parameter. Instead it always use
primary barometer. Bug was not detected because method
get_last_update() is used where instance is _primary.

Andrew Tridgell 8a1275356d AP_Baro: moved MS5611 reset before prom read 
thanks to Jacob and Lucas for pointing this out
 2016-12-13 11:10:35 +11:00
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

this adds sensor probing for barometers, simplifies the MS5611 driver,
and adds support for the I2C external barometers on Pixhawk2

Andrew Tridgell c2125a0078 AP_Baro: wait forever for semaphore on startup 2016-11-21 18:04:10 -02:00
Andrew Tridgell b16226dddf AP_Baro: fixed a bug with corrupted conversions in MS5611 driver 
the datasheet says that if you get back zero in an ADC read that the
next value can be corrupt. I have seen this happen on the FMUv1,
leading to bad altitude readings

Lucas De Marchi ae53920e5b build: don't build examples with old build system 
We currently check examples are buildable with waf which doesn't need
the libraries to be specified in a make.inc file.  Having the makefiles
there is misleading since people try to build and realize the build is
broken.

Andy Little 0d113b265c Examples: fix examples for px4

Lucas De Marchi e217faacab AP_Baro: MS56XX: cosmetic changes to members 
- reorder and document members.
    - remove tentative of vertical alignement
    - like was done for accumulated values, move the calibration
      values to a struct
 2016-07-30 00:55:28 -03:00
Lucas De Marchi f7b453359d AP_Baro: MS56XX: convert to threaded bus 
This converts MS56XX to use the thread started by SPI/I2C instead of
using the timer thread. This also fixes a possible starvation of the
main thread:

    1) INS driver registers itself to be sampled on timer thread
    2) MS56XX registers itself to be sampled on timer thread
    3) Main thread waits for a sample from INS with
       ins.wait_for_sample()
    4) timer thread is waiting on update from MS56XX and consequently
       the main thread is waiting on an I2C/SPI transfer

Besides this starvation there's another one due to reuse of the timer
lock in order to pump values from the timer thread to the main thread. A
call to the update() method when we have a sample available would need
to wait on any other driver holding the timer lock.

Now there's a lock just to pass the new values from the bus thread to
the main thread with a very tiny critical region, not waiting on any
bus transfers and/or syscalls.
 2016-07-30 00:55:28 -03:00
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 3c7d80a270 AP_Baro: BMP085: use a moving average of 10 samples in BMP085 
Instead of depending on the frequency accumulate() is called, use
AverageIntegralFilter with 10 samples. The data obtained by BMP085 is
too noisy with any value of OVERSAMPLING so use twice the number of
samples as currently used. Besides that now we are sure there's always
10 samples used in the average.
 2016-05-10 14:24:59 -03:00
Lucas De Marchi 8da5275b03 AP_Baro: BMP085: don't average temperature in BMP085 
The temperature readings is not subject to white noise so there's no
point in averaging its reading. Moreover since for a normal 50Hz
accumulate() / 10Hz update() it would read temperature only once per
update(), it's pointless to keep averaging and introducing rounding
error.

The temperature doesn't need to be checked as frequent as pressure, too.
The datasheet even suggests on section 3.3, page 10 to enable standard
mode and read the temperature at 1Hz. Here we reduce it to 2Hz
(considering the accumulate() function being called at 50Hz).

Lucas De Marchi e40b88aa70 AP_Baro: BMP085: use DigitalSource interface in BMP085 
Use the DigitalSource interface rather than going through the "static"

 2016-05-10 14:24:58 -03:00
Lucas De Marchi 56fa1b6214 AP_Baro: BMP085: change oversampling in BMP085 without EOC 
If we don't have EOC pin and assuming the accumulate() function is
called at 50Hz (or higher) we would take very few samples to accumulate
before the update is called. That's because since we have to wait 26ms
to get a sample and we calling accumulate() every 20ms, half of the
times it will return without getting anything.  So we will
be using 2 or 3 samples only to average.

If we don't have EOC, use OVERSAMPLING=2 which gives us more noise, but
that we can filter out by using measurements to average. When we have
EOC we don't need it because most of the time the conversion will take
less than 20ms: I'm getting 16ms on most of them while bench-testing.

AP_Serial abstraction since that is now handled by AP_HAL itself.

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 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.

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'.

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.

clamped at no higher than 25 degrees C, to prevent hot electronics
