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

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
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.
Detected with warnings, warnings are useful :-)
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
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
This param seems to have been un-implemented. This is putting it back in. Adds a meter offset to the calculated altitude form the baro sensors.
Also changes it from int8 to float
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.
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
