Paul Riseborough a8983d075f AP_NavEKF2: Enable clean entry into GPS aiding in-flight 
The setting of the EKF origin and the entry into GPS aiding mode have been separated to make the logic clear.
The order of operations has been changed to ensure that when a reset to GPS is performed, a valid GPS measurement is available in the buffer
Declaration of GPS availability is not made unless the GPS data has been entered into the buffer

Paul Riseborough f99dbc70f9 AP_NavEKF2: Don't return ready to use GPS true if user has inhibited GPS 2015-11-08 16:26:04 +11:00
Paul Riseborough d6f7156f4e AP_NavEKF2: Fix timing offset in position reset calculation 
the correction for GPS latency now uses the correct time for that observation

Paul Riseborough 803817821d AP_AHRS: Support changes to EKF2 interfaces that specify the instance 
An instance of -1 is specified which causes data for the primary instance to be returned.

Paul Riseborough 138315af21 DataFlash: Add logging for second NKF instance 2015-11-08 15:37:28 +11:00
Paul Riseborough 0b64ad0123 AP_NavEKF2: Enable EKF instance to be specified when requesting public data 
Only applied to interfaces required for data logging.
If an invalid instance is requested, the data for the primary instance is returned. This allows the primary data to be returned by calling with a -1 instance value.

Paul Riseborough 1858da8307 AP_NavEKF2: Better switching in response to faults 
Make selection sticky
If fault detected or unhealthy, then switch to healthy core with lowest fault score.
If no healthy core found, do not switch.

Paul Riseborough 04165a60a7 AP_NavEKF2: Reduce false positive on EKF health check 
Apply filtering to baro innovation check and and don't apply innovation checks once aiding has commenced because GPS and baro disturbances on the ground and during launch could generate a false positive

Paul Riseborough 49f9ea317c AP_NavEKF: Update console message and param descriptions for multiple EKF's 2015-11-08 15:37:26 +11:00
Paul Riseborough 2340e18fdc AP_NavEKF2: Offset the fusion time horizon between multiple instances 
Prevents frame over-runs due to simultaneous fusion of measurements on each instance.
The offset is only applied if less than 5msec available between frames
 2015-11-08 15:37:26 +11:00
Paul Riseborough 3eeff8dbc6 AP_NavEKF2: Remove unused code 
This method of correcting for the fusion time horizon delay was too computationally expensive for our application and did not smooth fusion noise.
 2015-11-08 15:37:26 +11:00
Paul Riseborough d48454ee2d AP_NavEKF2: Use nominated IMU unless unavailable 
We now run a separate instance of the EKF for each IMU, so input data fusion of IMU's is no longer required.

Andrew Tridgell 56909ce973 AP_NavEKF: split EKF1 into frontend and backend 
this allows the primary EKF to be allocated dynamically, allowing for
experiments with EKF2 with multi-IMU support

Andrew Tridgell 98ef21bc69 PX4: don't auto-start uavcan, use BRD_CAN_ENABLE instead 2015-11-06 10:23:54 +11:00
Andrew Tridgell c334bd0ddf AP_BoardConfig: added BRD_CAN_ENABLE option 
this allows uavcan to be enabled/disabled at boot. When it is disabled
we save about 25k of memory, allowing for more options for things like
multiple EKF

Lucas De Marchi e9c6702269 AP_HAL_VRBRAIN: fix typo using comma operator 
We want to return mallinfo().fordblks, not the struct using the comma
operator with a non-existing fordblks variable.

Lucas De Marchi 7b726d824d AP_OpticalFlow: remove num_errors increment due to busy bus 
num_errors should be used to detect bad bus transfers, not if we
actually read something. Since we are using i2c_sem->take_nonblocking()
failing here is more likely if the bus is shared.
 2015-11-05 16:11:58 +09:00
Lucas De Marchi 41ddb67712 AP_OpticalFlow: pack struct passed to I2C layer 
We pass "sizeof(i2c_integral_frame)" to hal.i2c->readRegisters(). Since
we have a padding in i2c_integral_frame we actually read 3 bytes more
than we should. Add PACKED to the struct so this is fixed.

i2c_frame doesn't have a padding (or hole) so there isn't this problem,
but since it's also used to calculate the frame size, use PACKED there
too.
