Andrew Tridgell f831c16238 AP_InertialSensor: use fixed sensor sample times
this uses fixed sample times for PX4 IMUs, rather than reported
timestamps. It avoids timing jitter caused by the over-sampling in
the PX4 drivers

Andrew Tridgell 3d7d46b9b0 AP_InertialSensor: replaced INS_MPU6K_FILTER with INS_ACCEL_FILTER and INS_GYRO_FILTER

Andrew Tridgell 6d39cf5e49 AP_InertialSensor: another attempt at fixing the spurious bad gyro health warnings
cope with _get_sample() not being called for a while

Andrew Tridgell f10a4b04ae AP_InertialSensor: make PX4 healthy call _get_sample()
this prevents a false positive during times like arming where we are
not reading the sensors
2013-11-10 17:03:16 +11:00
Andrew Tridgell f5299e2e11 AP_InertialSensor: added healthy check for PX4 and HIL

Andrew Tridgell 8532e2bff8 AP_InertialSensor: fixed timing of PX4 sensor samples 2013-10-13 22:15:50 +11:00
Andrew Tridgell e5e4cdee18 AP_InertialSensor: added wait_for_sample() API call
this waits for a new INS sample to arrive, using whatever method is
most efficient on each INS type

Andrew Tridgell 14636e1cdf AP_InertialSensor: changed num_samples_available() to sample_available()

Andrew Tridgell e5ad9dbd15 AP_InertialSensor: switch PX4 driver to fixed time per sample model
this makes the driver much simpler, and does away with the need for an
accumulate function
2013-08-30 13:01:33 +10:00
Andrew Tridgell 38fe89d661 AP_InertialSensor: switch to non-averaging system for PX4 IMUs
always use the latest value, based on a lowpass filter in the driver
2013-08-30 13:01:33 +10:00
Andrew Tridgell 46c5d18585 AP_InertialSensor: disable averaging on FMUv2
the new filter from Leonard means we shouldn't average values, and
instead just use the last value

2013-01-21 21:51:32 +11:00
Andrew Tridgell 3d0cb755d2 AP_InertialSensor: user a timer to drive data collection on PX4
this reduces the chance of missing a sample if the main sketch is a
bit slow

Andrew Tridgell 16d72ca160 AP_InertialSensor: update PX4 driver to use read() method 2013-01-20 22:13:20 +11:00
Andrew Tridgell 6142eac4b4 AP_InertialSensor: simplify get_delta_time() API
use a single float return rather than two APIs.

This also changes the MPU6k driver to match the new 2.9 behaviour of
using the MPU6k sample timing instead of micros()
