Andrew Tridgell 3cf0eebac8 DCM: don't reset _have_initial_yaw for GPS heading unless very slow 
wait till we reach 1m/s before we reset _have_initial_yaw. This
prevents us continually resetting the DCM matrix if our ground speed
is close to 3m/s.

Andrew Tridgell 42528e9c33 test: updated VARTest for new AP_Param vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell 17718720b1 GCS: force scalar type in copy_name() 
this enables access to compass offsets over MAVLink
 2012-02-25 11:37:20 +11:00
Andrew Tridgell 007a6b8958 AP_Param: added special handling for Vector3f 
We would like to be able to use Vector3f as a parameter while exposing
the individual elements of the vector as MAVLink parameters. This
change to AP_Param makes that possible, by giving AP_Vector3f a dual
personality

Andrew Tridgell 1d95137b71 SITL: added -C option to desktop mode 
this allows running APM to stdout, which is useful for test sketches

Andrew Tridgell c63ca9c697 DCM: tidy up use of error_course and in_motion 
in_motion is not a good name now it is also used for the compass

The error_course and heading component values don't need to be part of
the DCM object, they can be on the stack to reduce the memory usage a bit
 2012-02-25 11:37:20 +11:00
Andrew Tridgell d5b619218c DCM: use rotation_matrix_from_euler() to calculate initial yaw 
When we first get a compass reading or we first start motion we need
to setup the DCM matrix with the right yaw. This uses
rotation_matrix_from_euler() to get a DCM matrix corresponding to our
current roll/pitch, but with the correct yaw

Andrew Tridgell 48cad8bc25 DCM: use rotation_matrix_from_euler() in matrix reset 
this makes the code a bit easier to read
 2012-02-24 11:54:11 +11:00
Andrew Tridgell 5009679617 DCM: use calculate_euler_angles() to get eulers from DCM 
this makes the code a bit easier to understand
 2012-02-24 11:52:55 +11:00
Andrew Tridgell df6013616e AP_Math: added rotmat <-> euler functions 
these will make the dcm matrix manipulation easier to understand
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 4edf311865 ACM: ensure update_trig() doesn't cause NAN values for cos_roll/cos_pitch 
the DCM matrix could have a value over 1.0 for c.x due to rounding
errors
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 50f85835bd Compass: ensure we don't produce NAN values for compass heading 
this leaves the previous heading values alone if we are at a pitch of
exactly 90 or -90, at which point we can't compute a meaningful
heading
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 8190204287 AP_Math: added safe_sqrt() function 
this function will never return NAN. It will return zero for negative
numbers.
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 0acea11152 DCM: tidy up the nan checking in DCM 
use is_nan() on the matrix rather than just on c.x, and add
safe_asin() to the (unused) OUTPUTMODE==2 code.
 2012-02-24 11:52:55 +11:00
Andrew Tridgell b4c8d6491a DCM: added matrix recovery on reset 
when we get a bad DCM error we can recover a matrix corresponding to
the current attitude, making it more likely that the aircraft will be
able to recover
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 1a32ececb4 AP_Math: added a safe_asin() function 
this adds range checking to asin()
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 7dd909a16b AP_Math: added is_nan() methods to vector3f and matrix3f 2012-02-24 11:52:55 +11:00

Andrew Tridgell 8707965c15 DCM: changed the sense of floating point range comparison 
This allows us to detect NaN, otherwise NaN values were considered 
'in range'
 2012-02-23 11:41:26 +11:00
Andrew Tridgell 9caa4aeb44 DCM: range check the matrix before calculating pitch 
The asin() in the pitch calculation can only take values between -1
and 1. This change ensures that the value is in range, and if it isn't
then we force a normalization. If that fails we reset the matrix
 2012-02-23 08:16:08 +11:00
Andrew Tridgell 13693e1a04 DCM: reset more values on renorm blowup 
when DCM blows up, we need to reset a lot more variables to ensure
that any NaN values don't persist
 2012-02-23 08:16:08 +11:00
Andrew Tridgell b231112957 DCM: renorm_sqrt_count is now called renorm_range_count 2012-02-23 08:16:08 +11:00
Andrew Tridgell 5cfe1ad5dc DCM: remove the taylor expansion optimisation for renormalisation 
The sqrt() costs about 44usec on a 2560, which is small enough for us
not to worry about the speed.

This also changes the range of values where we declare a blowup to
much less likely, which means we can cope with larger delta_t glitches
