Andrew Tridgell 042265b4c4 AP_AHRS: fixed synthetic airspeed to be along +ve X axis
this prevents us from thinking we have +ve airspeed when flying
backwards with no pitot tube

Andrew Tridgell 239c18792a AP_AHRS: fixed dead-reckoning groundspeed vector
this is essential for RTL in planes on GPS loss

Andrew Tridgell 5b0b9ef962 AP_AHRS: don't do yaw correction in DCM while calibrating compass
this avoids applying bad compass yaw, and helps the compass
calibration code

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

Peter Barker 4ed7fb154f AP_AHRS: supply missing get_relative_position_D_home

position)

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.

dgrat 6d3b491c02 AP_Math: Replace is_equal with a type safe template function
It makes sense to consider also other floating point types.
2016-05-10 11:41:26 -03:00
dgrat 41661f815f AP_Math: Replace the pythagorous* functions with a variadic template
The new function can deal with a variable number of function parameters.
Additionally, I renamed the functions to norm(), because this is the
standard name used in several other projects.

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.

Andrew Tridgell 79d85f7e10 AP_AHRS: wait for up to 10 samples to get a valid accel vector
the initial accel vectors can be invalid

Jonathan Challinger c35605fa04 AP_AHRS_DCM: align tilt during initialization 2015-10-21 08:34:02 +11:00
Gustavo Jose de Sousa 84f811fe76 AP_AHRS: use compass get_{field,offsets}() functions
Both functions are equivalent, so we're going to simply use
get_{field,offsets}() instead of get_{field,offsets}_milligauss().

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 9c776736c1 AP_AHRS: use delta_velocity and delta_angle in DCM
this prevents an aliasing effect by using the correct delta velocity
time value for each accelerometer sample used

Andrew Tridgell 3529e02675 AP_AHRS: if we have 3 gyros then only use first two
the 3rd gyro on a PH2 has a lot more noise as it is not vibration
isolated
