Peter Barker d05ab1b983 AP_Baro: notify GCS of all barometer ground pressures 2018-10-11 08:05:05 +11:00
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

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 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

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.

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 
The change to use AP_BoardConfig messed up the examples. Here are some

- reorder and document members.

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.

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.

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 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.
