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!)

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

the old AP_ADC driver on the APM1

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.

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.

to prevent omega_I picking up short term responses

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

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.

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.

ArduCopter - AP_Motors library - added new library which has few advantages over current code:

1. it's step towards rearchitecting the current code base ahead of a move to RTOS.
2. internally it uses a MatrixTable for the Quad, Octa, OctaQuad, Y6 frames.
3. it implements the missing stability patch for Octa and OctaQuads (still missing for Y6)
Later check-ins will incorporate into the main ArduCopter code.

AP_Declination: The exception signs unpacking logic was incorrect. I was shifting a 1 value left y%8 which would have needed a the signs to be packed right to left. My packed signs byte was packed left to right (left most being the 0 position) so I needed to reverse the shifting.
2012-03-30 14:21:58 +11:00
f66c6e16e4
AP_Declination: In order for the bitwise & operation to work, negative signs need to be represented by 1s instead of 0s. Changed so that negative signs are represented by a 1 in the packed signs array. Updated lookup logic to reflect this change.
2012-03-30 14:21:58 +11:00

AP_Declination: Reduced the size of the lookup table to support -75 <-> 70 latitude range. This allows the datatype to remain int8_t.

AHRS: fixed error_yaw reporting with 2 MAVLink connections
...
when a user first connects with USB, and later switches to the

This ensures we give the last value after the counter is reset
