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.

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
2012-04-24 22:24:58 +10:00

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.

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.

AP_MotorsMatrix - fixed another compiler error regarding shadowing a variable. Fixed by removing those the angle and direction arrays which weren't even used
2012-04-05 00:24:56 +09:00
7a8973eaf0
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.
2012-04-05 00:06:33 +09:00

AP_Motors - fix compiler warning re shadowing a variable caused by badly named parameter in armed function.
...
Another compiler warning fixed in AP_MotorsMatrix.cpp caused by declaring "i" twice.
2012-04-04 23:59:51 +09:00
b71877366e
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.

0c445101ff
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
504c53f746
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
927834106d
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
70d4280935
AP_Declination: added timing information to declination test

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
23f6093f05
AP_Declination: Updated comments to reflect new LUT size.
2012-03-30 14:25:06 +11:00
50791a8b0f
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
f35e447927
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
72b70c394c
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
076192db51
AP_Declination: Updated test to run in 5 degree increments. Changed to only print failures and also print total pass vs total fail.

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
e0fa053c79
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
d88b9e8ffc
AP_Declination: Updated packed exception signs array. I had the signs packed incorrectly.
2012-03-30 14:21:57 +11:00
036da88174
AP_Declination: Changed test to run in increments of 10 degrees. 1 was too granular.
2012-03-30 14:21:57 +11:00
580b274bde
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
efefc3e4f4
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
0dcc4e8307
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
3a849771bc
AP_Declination: Changed PROGMEM read function to pgm_read_word_far to support the int16_t datatype.

370e56c00a
AP_Declination: Changed datatype to int16_t to support the -90 <-> 90 latitude range.
2012-03-30 14:21:57 +11:00
ae257ad42b
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

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

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
