Andrew Tridgell 8f4ce7f20b build: removed all nocore.inoflag files 
these were APM2 specific

Paul Riseborough 803817821d AP_AHRS: Support changes to EKF2 interfaces that specify the instance 
An instance of -1 is specified which causes data for the primary instance to be returned.

Lucas De Marchi dd784189a1 AP_AHRS: remove comment about avr-libc 2015-11-04 12:14:16 +11:00
Lucas De Marchi da86e29c27 AP_AHRS: remove check for AVR CPUs 
Remove the checks for HAL_CPU_CLASS > HAL_CPU_CLASS_16 and
HAL_CPU_CLASS >= HAL_CPU_CLASS_75. Corresponding dead code will be
removed on separate commits.
 2015-11-04 12:14:14 +11:00
Lucas De Marchi 124937ab61 AP_AHRS: remove checks for HAL_BOARD_APM2 and HAL_BOARD_APM1 2015-11-04 12:14:11 +11:00
Paul Riseborough 7ed36d8e65 AP_AHRS: Enable pre-flight GPS check status reporting for EKF2 2015-11-02 14:12:17 +11:00
Lucas De Marchi 20c6ffc5e3 Replace use of UARTDriver::printf_P() with UARTDriver::printf() 
This also starts to show warnings on places that were already using
wrong printf format strings.
 2015-10-30 14:35:25 +09:00
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 f7c73fbb13 AP_AHRS: remove AHRS_EKF_USE_ALWAYS define 
This option now is passed when instantiating the code in ArduCopter, so
selecting the default value at compile time is not necessary anymore.

The motivation is to move vehicle specifc code out of the general
libraries. This patch shouldn't change behavior.
 2015-10-21 11:01:11 +11:00
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 e87db31149 AP_AHRS: remove unused define 
AHRS_EKF_USE_DEFAULT is not used since commit

EKF type using AHRS_EKF_TYPE".

Caio Marcelo de Oliveira Filho 9b73fcb6f8 AP_AHRS: remove unnecessary includes in the example 2015-10-21 09:16:11 +11:00
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'.

Paul Riseborough e65ae51564 AP_AHRS: Enable AP_InertialNav to access all EKF functions via AP_AHRS 
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 84f811fe76 AP_AHRS: use compass get_{field,offsets}() functions

Lucas De Marchi b43bddc0af AP_AHRS: standardize inclusion of libaries headers

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.

Andrew Tridgell 4ad643b233 AP_AHRS: use a common function for updating the CD values 
this ensures the wrapping of yaw is consistent between the 3 use cases
 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
Andrew Tridgell 809b6cc855 AP_AHRS: added get_yaw_rate_earth()
