faeda3713e AP_AHRS: removed DCM_test example sketch 
No longer required because it doesn't compile and is redundant anyway because the AP_AHRS_DCM class is tested in the AHRS_Test example sketch.

3849ca8b5c AHRS: make DCM drift correction not rely on accurate yaw 
this uses a new formulation of the GPS based drift correction from
Bill Premerlani that rotates the error vector to avoid relying on
accurate yaw. This means we should get accurate roll/pitch correction
even with lots of magnetometer interference

It also makes it possible to fly a multicopter with no compass. It can
even navigate and correct yaw (slowly!)

99b11e4f19 Mount: enable mount control via eeprom parameters 
this enables MNT_* parameter control of the camera mount code. It also
fixes the conversion of calculated angles between degrees and
integers, and fixes stabilised mount control when yaw control is not
available.

057eb5e6f6 Baro: average over all pressure/temperature samples on MS5611 
this allows us to use the MS5611 barometer at its full 100Hz sample
rate (80Hz for pressure, 20Hz for temperature). The pressure and
temperature values are averaged between reads without adding any
latency. Previously the driver would throw away values between
readings

This also fixes a race condition in reading from the SPI bus that
could lead to bad values from the barometer

Andrew Tridgell
c8befe4536 AnalogSource: make the Arduino AnalogSource interrupt driven 
this fixes several problems with reading analog sources:

 - we were getting poor values because we didn't wait long enough for
   an analog source to settle

 - we wasted a lot of CPU cycles waiting for conversions

 - we were not taking averages over many samples, which we did with
   the old AP_ADC driver on the APM1

37fc6c46b9 AHRS: disable barometer for vertical acceleration 
this seems to have been the cause of the 'flips' seen by Marco and
others. Testing by Craig and Alan shows that the flips are gone when
the barometric acceleration is removed.

It looks like a 5 point average filter is not enough to keep the
vertical acceleteration noise low. With high noise in the z axes, the
x and y axes are scaled back when the ge vector is normalised.

37e2f2ee2c AHRS: implement spin rate limits 
this follows the method that Bill developed in his fastRotations
paper. We've demonstrated that this is indeed needed in APM, as we
were able to produce the 'dizzy' effects in both the ArduPlane and
ArduCopter simulator

Andrew Tridgell
e4d28b12e5 Compass: remove the need to call calculate() on the compass object 
the new AHRS code doesn't use calculate() and the compass.heading
attribute. Instead it works on the raw magnetometer vector. This
change removes the internal calculate state from the compass object
and instead adds calculate_heading() for use by older code that
doesn't go via AHRS.

This significantly reduces the calculation involved in compass updates

The null offsets enable/disable code is also removed, as it is not
needed now that compass offsets are not linked to the AHRS state.

3a41ad8e7c AHRS: normalize the ge vector in drift correction, and use barometer 
The normalisation ensures the error term scales uniformly with
different accelerations.

The barometer is used for vertical acceleration estimation
 2012-06-27 16:01:50 +10:00
Andrew Tridgell
c387edd74c Baro: added get_altitude() and get_climb_rate() interfaces 
this allows the barometer driver to calibrate and return altitude and
climb rate values. This will be used by the AHRS drift correction code
for vertical velocity

The climb rate uses a 5 point average filter

d230690b7b AHRS: brought DCM more inline with Bill's implementation 
omega_I applied continuously. _ki larger. Stop integrating when _omega.length()>20

d4c8041c51 AHRS: first successful version of Bills new drift correction system 
This makes 3 major changes:

 1) fixes the scaling of the yaw drift correction term to fix the time
 constant

 2) don't integrate the mag vector over multiple readings

 3) accumulate omega_I changes over 15 seconds before applying, to try
 to prevent omega_I picking up short term responses

296e651b30 GPS: fixed the UBLOX parser to handle unknown messages 
the parser was broken in several ways:

 1) when it received an unknown message it didn't update the ck_a and ck_b fields, so it
    thought the message had a bad checksum, which meant it got out of protocol sync

 2) the read() method would return false if the last message from the GPS was of an unknown type. 
    So we relied on the last msg always being one that we understand and want

 3) the parser considered any valid UBLOX message to be 'new data', whereas we only actually get 
    a new fix when we get box a new position and velned message

 4) the total message size per update is more than 128 bytes, but the serial port was opened 
    with only a 128 byte buffer, so we got corruption regularly

2a3af369b6 DCM: buffer omega_I changes over 10 seconds 
this buffers up _omega_I changes in _omega_I_sum over a period of 10
seconds, applying the slope limit only when _omega_I_sum is
transferred to _omega_I.

The result is a huge improvement in the ability of _omega_I to track
gyro drift over the long term.

f27d85cb8d DCM: drop the 'drop z' method 
the 'drop z' method reduced the impact of noise on omegaI, but it also
made us more sensitive to errors in accelerometer calibration and
scaling, as demonstated by the logs from Gabor here:

  http://diydrones.com/xn/detail/705844:Comment:834373

Simulation testing shows that the other noise suppression methods
applied in the DCM code, in particular the slope limiting on omegaI
the removal of the weighting and the upcoming use of a _omega_I_sum
buffer have reduced the impact of noise enough that we can now safely
include z in the acceleration calculation.

     3. it implements the missing stability patch for Octa and OctaQuads (still missing for Y6)

eac8b66385 AP_Param: Make nested group recursion disableable by macro 
* Eliminates recursive calls inside AP_Param.
  This is important to Pat @ Galois, but not the project in general.
  Recursion depth on these functions is bounded structurally using
  existing nested group constructors (can't create loops in finite space)
  and checked at init time

a432232db9 AP_Param: fixed v.load() on a sub-element of a AP_Vector3f 
this isn't actually used at the moment in APM, but we should get it
right in case someone does try to load a single element of a vector

87a6d97f7b AP_Param: fixed setting of CAM_P_G in ArduCopter 
the variable CAM_P_G has the same prefix as the CAM_P group. We want
to allow for parameters having a common prefix with a group, so we
need to keep searching after we've found a group that matches the
prefix

d0a6359b37 Compass: use constructor to set initial values for _learn and _use_for_yaw 
this ensures they are set if you have MAG_ENABLE==0
 2012-02-25 17:36:31 +11:00
Andrew Tridgell
900388a85a DCM: disable compass null offsets when setting initial yaw 
we need to ensure the compass null offsets code doesn't see a sudden
yaw change, or it will change the offsets by a large amount very
suddenly
 2012-02-25 16:02:24 +11:00
Andrew Tridgell
f59297d7a7 Compass: catch the case of a user enabling a compass mid-flight 
if a compass has not been initialised at startup we can't enable it
mid-flight, as we don't have the orientation
 2012-02-25 14:51:09 +11:00
Andrew Tridgell
eb71b26d3f DCM: use the new use_for_yaw() compass method 2012-02-25 14:51:09 +11:00
Andrew Tridgell
664622523d Compass: added COMPASS_LEARN and COMPASS_USE parameters 
these allow you to control if the compass should be used for yaw and
if it should learn its offsets. This is useful for locking in compass
offsets once they are confirmed to be good, and for learning offsets
without using them in flights.

The default is to behave the same as previously, which is
COMPASS_LEARN=1 and COMPASS_USE=1

f10097a6d5 AP_Param: added some comments on AP_Vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell
5e2fbdb6cf 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.
 2012-02-25 11:37:20 +11:00
Andrew Tridgell
2e9105c68a 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
 2012-02-25 11:37:20 +11:00
Andrew Tridgell
d6bfceef7c SITL: added -C option to desktop mode

55e33c3359 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
ab8cc3d478 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
 2012-02-25 11:37:20 +11:00
Andrew Tridgell
ddeda1c367 DCM: use rotation_matrix_from_euler() in matrix reset

Andrew Tridgell
06f37aad75 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
16ed8bc8f6 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
c354879f1f 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
17d16bc8c6 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
bad653f230 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
c8e6d03c67 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
502fbf6e17 AP_Math: added a safe_asin() function

ef90f336d3 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
57ffd00b69 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
2bb58db3f7 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
156d98cb9f 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
 2012-02-23 08:16:08 +11:00
Andrew Tridgell

Andrew Tridgell
9793d04ed1 SITL: increase the amount of noise in the simulated ADC 
this increases the noise to 2 bits, which actually can have the effect
of improving accuracy, as it leads to better averaging

Andrew Tridgell
d52cb7e574 DCM: only add in centripetal accel if we have GPS lock 
if we don't have a GPS or the GPS doesn't have a good lock then we
can't rely on the ground speed for adjusting the acceleration vector

Andrew Tridgell
80a6773b8b AP_Param: added an initialised() method

62b104cbfa Found free extra 256 bytes of RAM eliminate _clz use from libgcc 
Believe it or not, changing / 2^31 to >>31 saved 256 bytes in the "d" segment.

The reason is that GCC version prior to 4.3.5 does not have a count_leading_zeros (clz) assembler macro, so it uses a 256 byte lookup table called _clz
The _clz table gets pulled in if you do 64 bit division.
This tiny change is the only place that we do long long division.
Changing to a shift saves 256 bytes of ram.

79d622939a ADC: on channel overflow we should not zero last_ch6_micros 
this happens every 64 seconds because of unused channels on the

down.
 2012-02-15 08:50:45 +11:00
Andrew Tridgell
601a991a46 added SITL_debug() macro

9175ebe33a change back to 256 max variables in _var_info[] 
this keeps the header to 24 bits, and allows the token to be 16

Andrew Tridgell
f2a6a31645 AP_Param: added group idx, and change packing of header elements 
adding a idx element to the GroupInfo will make it less likely that a
developer will change the IDs of group elements, and make it easier to
see that these IDs are important for identifying a variable in EEPROM

The header packing has changed to make it 24 bits on all platforms,
which allows us to lower the EEPROM variable max size to 1024 bytes
again

e22a83eec0 Add a CLI setup action to reset the magnetometer offsets 
Since the magnetometer offsets are not available through the MAVLink parameter interface (since they are an AP_Var vector) this little feature allows them to be reset from the CLI.  Useful if you somehow get bad offsets or if you change magnetometer.  If you have a bad set of large offset values I have seen issues with the nulling algorithm have trouble converging to the proper values.  I have never seen it have trouble converging from 0/0/0, so this could be a useful feature from time to time.

15d446bde2 DCM: prevent a segmentation fault when compass is not enabled

9846822748 Bug fix for compass. 
This is a fix for an interesting bug when a DCM matrix reset was added to the ground start.  This bug only showed up if (A) a ground start were performed after an air start or due to use of the "Calibrate Gryo" action, (B) if the current orientation were sufficiently different from 0/0/0, and (C.) if the particular magnetometer had sufficiently large offsets.  Why did resetting the DCM matrix to 0/0/0 pitch/roll/yaw at ground start cause a bug?  The magnetometer offset nulling determines the proper offsets for the magnetometer by comparing the observed change in the magnetic field vector with the expected change due to rotation as calculated from the rotation in the DCM matrix.  This comparison is made at 10Hz, and then filtered with a weight based on the amount of rotation to estimate the offsets. Normally it would take considerable time at normal in-flight rotation rates for the offset estimate to converge. 

If a DCM matrix reset occurs when the offset nulling algorithm is up and running, the algorithm sees the DCM reset as a instantaneous rotation, however the magnetic field vector did not change at all.  Under certain conditions the algorithm would interpret this as indicating that the offset(s) should be very large.  Since the "rotation" could also have been large the filter weighting would be large and it was possible for a large erroneous estimate of the offset(s) to be made based on this single (bad) data point.

To fix this bug methods were added to the compass object to start and stop the offset nulling algorithm.  Further, when the algorithm is started, it is set up to get fresh samples.  The DCM matrix reset method now calls these new methods to stop the offset nulling before resetting the matrix, and resume after the matrix has been reset.
