Robert Lefebvre 716ce6a5a7 Change to prevent Tricopter servos from going hard-over during Disarmed state.
Believe this was an oversight when the change to AP_Motors went in.

Robert Lefebvre ab1212d8d2 Instituting Yaw Differential on Multirotors. Intent is to stop "rise on yaw input".
Since motors with increasing speed due to yaw input seem to generate more thrust that motors that slow lose thrust, thus net thrust goes up, causing copter to climb.
Values are a guesstimate, proven out by test flying.  This could probably become a parameter.

Craig Elder 0534ac12b1 DataFlash: The current method for checking if chip erase worked is producing false positives. We are forcing the block erase until we have a deterministic test method. 2012-07-09 15:23:35 -07:00

Andrew Tridgell 7bc724d118 APM: changed PID library to do automatic deltat calculation

time base and prevents similar bugs from happening in the future

Andrew Tridgell 44755bf3ce AP_Baro: improved barometer averaging
this changes the barometer calculations to floating point. On a MS5611
this is actually about twice as fast as the previous 64 bit
calculations, but gains us more accuracy as we are able to take
advantage of sub-bit precision when we average over 8 samples.

Andrew Tridgell 43d6015811 Filter: split the DerivativeFilter steps into update() and slope()
this allows us to apply new data at a different rate than we calculate
the slope.

Andrew Tridgell 4723698489 AP_Baro: update MS5611 test to use baro library altitude 2012-07-06 15:11:30 +10:00
Andrew Tridgell 9845a55cb1 AHRS: make the yaw independent drift correction optional and disable
the new correction algorithm copes poorly with gyro drift, leading to
signification attitude errors in the face of drift
2012-07-06 15:11:30 +10:00
Andrew Tridgell e33554a1f9 AHRS: only enable barometer for AHRS if it is smooth enough
if we used less than 5 samples to compute the pressure then don't use
it for climb rate

Andrew Tridgell a07e280eda Filter: cope with non-uniform time steps in the DerivativeFilter

Andrew Tridgell 9d7ed30023 AHRS: only use GPS for yaw when compass is not being used
this avoids having two competing controllers
2012-07-05 13:00:46 +10:00

AHRS/DCM
2012-07-04 21:05:22 +10:00
rmackay9 cac0757c2e 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.
2012-07-04 18:22:51 +09:00
Andrew Tridgell 03516b7dfa 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!)
