Andrew Tridgell 770b7b5901 AP_InertialSensor: prevent a lockup in MPU6000 driver 
thanks to the VRBrain port for noticing this bug.

Failing to get the semaphore is an expected error with the MPU6000, as
we read data both from timer context and mainline code. That means
semaphore conflicts are inevitable. We shouldn't consider them an
error, and shouldn't panic when some arbitrary number of them have
happened since boot.

Instead the wait_for_sample() code checks that we receive new data at
least every 50ms. That is a much safer test.

zlite 4800c57fb4 Fixed cosmetic typo in user display message

 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

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()
