"%S" is used for wide string, but we are passing a char*. Use lowercase

Most of AP_Progmem is already gone so we can stop including it in most
of the places. The only places that need it are the ones using
pgm_read_*() APIs.
In some cases the header needed to be added in the .cpp since it was
removed from the .h to reduce scope. In those cases the headers were
also reordered.
prog_char and prog_char_t are now the same as char on supported
platforms. So, just change all places that use them and prefer char
instead.
AVR-specific places were not changed.
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.
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.
In order to avoid confusion between sample rate from sensor and sample rate
from the frontend class (AP_InertialSensor), use "raw sample rate" to refer to
the former.
The changes in the code were basically done with the following commands:
git grep -wl _accel_sample_rates | xargs sed -i "s,\<_accel_sample_rates\>,_accel_raw_sample_rates,g"
git grep -wl _set_accel_sample_rate | xargs sed -i "s,\<_set_accel_sample_rate\>,_set_accel_raw_sample_rate,g"
git grep -wl _accel_sample_rate | xargs sed -i "s,\<_accel_sample_rate\>,_accel_raw_sample_rate,g"
git grep -wl _gyro_sample_rates | xargs sed -i "s,\<_gyro_sample_rates\>,_gyro_raw_sample_rates,g"
git grep -wl _set_gyro_sample_rate | xargs sed -i "s,\<_set_gyro_sample_rate\>,_set_gyro_raw_sample_rate,g"
git grep -wl _gyro_sample_rate | xargs sed -i "s,\<_gyro_sample_rate\>,_gyro_raw_sample_rate,g"
And also with minor changes on indentation and comments.
This commit basically moves delta angle calculation that was previously done in
AP_InertialSensor_PX4 to a common place. Instances must publish their gyro raw
sample rate to enable delta angle calculation.
This commit basically moves delta velocity calculation that was previously done
in AP_InertialSensor_PX4 to a common place. Instances must publish their accel
raw sample rate to enable delta velocity calculation.
In order to allow other libraries to use the InertialSensor we need a
way to let them to get the only instance of InertialSensor. The
conventional way to do a singleton would be to let the constructor
private and force it to be instantiated from the get_instance() method.
Here however we just call panic() on the constructor if there's already
an instance alive. This allows us to let the vehicles as is. Later we
can change it so they call the get_instance() method instead.
Add an AuxiliaryBus class that can be derived for specific
implementations in inertial sensor backends. It's an abstract
implementation so other libraries can use the auxiliary bus exported. In
order for this to succeed the backend implementation must split the
initialization of the sensor from the actual sample collecting, like is
done in MPU6000.
When AP_InertialSensor::get_auxiliary_bus() is called it will execute
following steps:
a) Force the backends to be detected if it's the first time it's
being called
b) Find the backend identified by the id
c) call get_auxiliary_bus() on the backend so other libraries can
that AuxiliaryBus to initialize a slave device
Slave devices can be used by calling AuxiliaryBus::request_next_slave()
and are owned by the caller until AuxiliaryBus::register_periodic_read()
is called. From that time on the AuxiliaryBus object takes its ownership.
This way it's possible to do the necessary cleanup later without
introducing refcounts, that we don't have support to.
Between these 2 functions the caller can configure the slave device by
doing its specific initializations by calling the passthrough_*
functions. After the initial configuration and register_periodic_read()
is called only read() can be called.
Identify backend with an id, allowing other libraries to connect to
them. This is different from the _product_id member because it
identifies the sensor, not the board the sensor is in, which is
meaningless for our use case.
This allows backends to have a separate detection and initialization
logic. It doesn't change any backend yet and with the current code
there's no change in behavior either. This only allows
AP_InertialSensor::_detect_backend() to be called earlier so
AP_InertialSensor object can be used by other libraries. If it's not
called, later on AP_InertialSensor::init() will detect and start all
backends.
very strict check that all axis are not vibrating much at all
new param: INS_STILL_THRESH used to be a vibration threshold for different platforms
// @Description: Threshold to tolerate vibration to determine if vehicle is motionless. This depends on the frame type and if there is a constant vibration due to motors before launch or after landing. Total motionless is about 0.05. Suggested values: Planes/rover use 0.1, multirotors use 1, tradHeli uses 5
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.
Different detect() function might need different arguments and passing a
pointer to function here is cumbersome. For example, it forces to have a
method like "detect_i2c2" rather than allowing hal.i2c2 to be passed as
parameter.
This adds the backend driver for LSM9DS0. This implementation is based on the
legacy driver coded by Víctor Mayoral Vilches (under folder LSM9DS0) and makes
some necessary adaptations and fixes in order to work properly. The legacy
driver folder was removed.
The calibration on LSM9DS0 was giving offsets between 4.0 and 4.2 on x-axis and
around 3.6 on y-axis. It turned out that those offsets were actually right.
The maximum absolute values of calibration offset should be a sensor
characteristic rather than a constant value for all sensors.
The constant value previously used (3.5 m/s/s for all axes) is set here as a
default maximum absolute calibration offset for every instance to keep it
working.
