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
 2013-08-30 13:01:33 +10:00
Julian Oes c3b27629ec AP_InertialSensor: run PX4 FMUv2 at 800Hz

 2013-02-06 16:34:33 -08:00
Andrew Tridgell 1121254606 AP_InertialSensor: added filter frequency support to PX4 driver 2013-02-07 11:20:45 +11:00
Andrew Tridgell 5643c371b9 AP_InertialSensor: removed unused new_data_available() and temperature() APIs 2013-02-07 10:23:37 +11:00
Andrew Tridgell 7b1245937c AP_InertialSensor: always sample at 200Hz in MPU6000 
this changes the sampling to 200Hz regardless of requested rate, and
it is downsampled inside num_samples_available() using a shift. This
gives better noise resistance in ArduPlane.

This patch also makes it possible to update the filter frequency while
running, which is very useful for bench testing with a vibration
source

 2013-01-21 21:51:32 +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()
