Andrew Tridgell 520e33261a AP_AHRS: fixed EKF type 10 for SITL 
this fixes the use of EKF type 10 in SITL, preventing it from using
the DCM attitude estimate.

This is especially important for RealFlight and XPlane

Peter Barker 4d944da530 AP_AHRS: add a singleton-getter cast into AP_AHRS_NavEKF 
This will allow libraries which absolutely require the EKF to easily get
a cast copy of the singleton.

Storing home in the AHRS object but not its state is clearly evil.

Andrew Tridgell 0ccaa5bcba AP_AHRS: 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

Andrew Tridgell 1f9a3dd1bd AP_AHRS: improved init attitdue in DCM 
this tries harder to get a good IMU sample for the initial attitude
estimate. I have seen cases of bad IMU data on startup and this makes it
much less likely

Lucas De Marchi 40fd1b346c global: remove rangefinder from AP_AHRS_NavEKF 
AP_AHRS_NavEKF doesn't use the rangefinder, it just delegates the
calls to the right estimator.

For libraries/AP_AHRS/examples/AHRS_Test/AHRS_Test.cpp the initialization
order has also been modified to match the order on vehicles. It's more
correct since it passes a reference when EKF2/EKF3 are already
constructed, while thos constructors use a pointer.  Ideally these
should be moved to an init() method though, or use a get_instance().

Andrew Tridgell c62fc336cb AP_AHRS: use current EKF2 IMU core in gyro estimate 
The EKF2 implementation uses one IMU per EKF2 core. When reporting the

the values associated with the current IMU index being used by the
current EKF2 core. Otherwise we will have an inconsistency between the
gyro estimate and attitude estimate

places which spans to multiple lines, removing the matching parentheses.

The motivation is to move vehicle specifc code out of the general
libraries. This patch shouldn't change behavior.

Caio Marcelo de Oliveira Filho 9d2e3157fe AP_AHRS: add a runtime flag for always using EKF 
The AHRS_EKF_USE_ALWAYS define is used to force EKF to be always
used. It is defined only for building ArduCopter. Change it to be a
runtime flag. Keep its default value still based on the original define,
once the Copter uses it the define will be removed.

The motivation is to move vehicle specifc code out of the general
libraries. This patch shouldn't change behavior.

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.
 2015-10-21 09:16:07 +11:00
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'.

This patch adds additional methods to the the AHRS library so that the AP_InertialNav library dow nto have to access the EKF directly. This enables Copter to fly using the EKF nominated by AHRS_EKF_TYPE.
It will also pave the way to elimination of the AP_InertialNav library.

Gustavo Jose de Sousa 54d5277842 AP_AHRS: 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.

 2014-10-15 13:18:08 +11:00
Andrew Tridgell eec5cd5add AP_AHRS: restore DCM attitude before update() 
The DCM drift correction code uses the current attitude to calculate
error values to update its gyro drift correction. If we were using EKF
then without this patch the DCM code running as an alternative AHRS
source would be using the EKF attitude for calculating the error
value, leading to very bad gyro drift estimation
 2014-10-15 11:15:33 +11:00
Andrew Tridgell 63c06ea2af AP_AHRS: fixed calls to DCM in parent class 
use_compass() and reset() are common to AP_AHRS_DCM and
AP_AHRS_NavEKF. As AP_AHRS_NavEKF is a child of AP_AHRS_DCM, when we
call use_compass() from within AP_AHRS_DCM we actually end up calling
AP_AHRS_NavEKF::use_compass().

This has the effect of disabling the compass in DCM when EKF is active
and EKF has decided not to use the compass. That means that the DCM
yaw (and in fact the whole attitude) can get badly off while EKF is
enabled, making DCM an ineffective fallback if EKF fails.

The fix is to call the specific class versions of use_compass() and
reset()
 2014-10-15 10:12:50 +11:00
