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

this fixes several problems with reading analog sources:

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

MAVLink: removed the cpp part of the library
...
this was preventing building MAVLink 1.0 with the arduino GUI as we
can't set cpp defines

APM_RC: added OutputCh_current() method
...
this allows logging of the actual servo output values. The radio_out
method previously used doesn't take account of the various override
mechanisms available via waypoints

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.

346ca5c865
DataFlash_APM2 - moved CS_inactive call (which disables the dataflash) from the beginning to the end of all methods. This means the dataflash does not monopolize the SPI bus.
...
Also formatting changes to use tab instead of space. Sorry, should have done this as a separate check-in to the above changes.

e9f0103063
AP_MotorsHeli - fixed compiler warning re move_swash function declared with int parameters in .h file but actually using int16_t in .cpp file. They're the same in arduino but perhaps the build checker is a little more strict that Arduino.

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.

FastSerial: added set_blocking_writes() interface
...
this allows us to put a serial port into non-blocking mode, so that
writes that don't fit in the transmit buffer are dropped. This will be
used in flight to prevent stray printf() calls from causing large time
delays in the code

examples: fixed build of some examples with new AP_Declination code
2012-03-30 14:25:27 +11:00
825340d53d
Compass: added COMPASS_AUTODEC option
...
when this is 1 (which is the default), we will get the declination
automatically via the AP_Declination library
when it is 0 we will use the value configured by the user
2012-03-30 14:25:27 +11:00
e4e052ff91
AP_Declination: save some more memory by putting the declination keys in progmem
...
there was a comment saying this was too slow, but it actually costs
about 30 usec extra, which is trivial given the full auto declination
call costs 680 usec and its only called once per boot
2012-03-30 14:25:27 +11:00

AP_Declination: Update LUT based on the changes that I made in the LUT generation code. This LUT is the final version that has no truncation.
2012-03-30 14:25:26 +11:00
380b9ece44
AP_Declination: Updated comments to reflect new LUT size.
2012-03-30 14:25:06 +11:00
c04e074c89
AP_Declination: Removed trailing zero deltas as they have no impact on the final value and only take up extra bytes.
2012-03-30 14:21:58 +11:00
662f11f801
AP_Declination: Updated compressed lookup value table. Located 9 more failure points due to truncation on the packed LUT.
2012-03-30 14:21:58 +11:00
0178906389
AP_Declination: Found 7 of the 22 failure points and fixed them. The issue with those 7 was the way I originally packed the value array. The last delta values on some rows were getting truncated. The new number of failures is down to 15 - WIP.
2012-03-30 14:21:58 +11:00
08259bb2de
AP_Declination: Updated test to run in 5 degree increments. Changed to only print failures and also print total pass vs total fail.
2012-03-30 14:21:58 +11:00
64c236800c
AP_Declination: Moved check for y index of zero to after the y index is properly transformed.
2012-03-30 14:21:58 +11:00
e99d26cfa3
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
d9c9e0e608
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
8b1c383f97
AP_Declination: Updated packed exception signs array. I had the signs packed incorrectly.
2012-03-30 14:21:57 +11:00
c0813f8d62
AP_Declination: Changed test to run in increments of 10 degrees. 1 was too granular.
2012-03-30 14:21:57 +11:00
289d7a2784
AP_Declination: Added original array to test sketch. Added loop to validate new compressed array against original in 1 degree steps.
2012-03-30 14:21:57 +11:00
63ce400f77
AP_Declination: Moved rows with large spikes in delta to their own unsigned exception rows. The signs are in a separate packed array.
2012-03-30 14:21:57 +11:00
782c1aaaa3
AP_Declination: Implemented Delta Encoding and Run-Length Encoding. Added method to traverse the compressed array and return the lookup value based on the same lat_index/lon_index that was used before.
2012-03-30 14:21:57 +11:00
9888a4730f
AP_Declination: Changed PROGMEM read function to pgm_read_word_far to support the int16_t datatype.

d883bdf75e
AP_Declination: Changed datatype to int16_t to support the -90 <-> 90 latitude range.
2012-03-30 14:21:57 +11:00
719636d00c
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
telemetry port without restarting we were getting zero for error_yaw
in the logs, as AHRS.get_error_yaw() was being called twice.
This ensures we give the last value after the counter is reset

Compass: implement Bills new offset nulling algorithm
...
this seems to work much better than the old algorithm, converging
faster and more accurately. Even better, it has no linkage to DCM, so
no possibility of nasty feedback effects

APM_RC - moved Force_Out0_Out1, Force_Out2_Out3 and Force_Out6_Out6 to APM_RC parent class because it's already implemented in the APM1 and APM2 child classes anyway
2012-03-25 21:13:31 +09:00

fb9790e1f4
Math: moved matrix multiple operations to .cpp file
...
this means we only link this in once, rather than for every use of
matrix multiply, which saves us some flash space
We need to be careful not to put large pieces of code in template
headers, as if the operation is used a lot, it costs us a lot of code
space
