Gustavo Jose de Sousa 7789aec85b AP_InertialSensor: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Lucas De Marchi eb4e2ac2e5 AP_InertialSensor: factor out MPU9250 initialization
Now we have the initialization code split in 2 parts:

1) Making sure the MPU9250 chip is alive and working: this is now in a
static function that may be called by other drivers that use MPU9250 as
backend.

2) The configuration of gyro and accel. Once the first part is completed
successfully the AP_InertialSensor_MPU9250 finishes the configuration of
the sensors it uses.

The only change in behavior here is that before we would try 25 time (5x
inside _hardware_init time 5x inside _init_sensor() that calls the first
function) to "boot the chip" and now we are doing "only" 5.

Lucas De Marchi 953bfbd3fe AP_InertialSensor: provide static methods for spi transactions
Add static methods to do the SPI transactions and provide the wrapper
methods when we have an instance of the object. This is useful so these
methods can be called from other contexts when the AP_InertialSensor
hasn't been initialized yet.

Gustavo Jose de Sousa c72dc9bd45 AP_InertialSensor: make single rotation on MPU9250
The previous implementation made some boards apply two rotations to suit
their default orientation. That was happening because there was an
unconditional rotation being done (commented as "rotate for bbone
default").

This commit makes that unconditional rotation as a default rotation
instead and adjusts the former additional rotations to be single
rotations.

Andrew Tridgell 3d7d46b9b0 AP_InertialSensor: replaced INS_MPU6K_FILTER with INS_ACCEL_FILTER and INS_GYRO_FILTER
this allows filtering to be set separately on accels and gyros where possible

Jonathan Challinger 502446d821 AP_InertialSensor: use LowPassFilter2pVector3f 2015-03-12 12:50:27 +11:00
Andrew Tridgell a047d1f569 AP_InertialSensor: moved default filter and sample_rate to frontend
this simplifies the backends and prevents code repitition

Andrew Tridgell dcef9bb3b8 AP_InertialSensor: converted the MPU9250 driver to new API 2014-10-24 12:10:37 +11:00
Andrew Tridgell dcdb53584b AP_InertialSensor: use lockless structures in MPU9250 driver
this avoids suspending timers when transferring data between main
thread and SPI read thread

Andrew Tridgell a14f8dbd0a AP_InertialSensor_MPU9250: use micros64() and millis64() 2014-08-20 08:02:34 +10:00
Andrew Tridgell 3c2ab31415 AP_InertialSensor: get rid of data_ready for MPU9250
when running off a 1kHz timer and reading at 1kHz it is better to
double sample than it is to skip a sample, as skipping samples will
throw the filter off, whereas a double sample will have minimal effect

Andrew Tridgell 9e01c657e5 AP_InertialSensor: update MPU9250 driver for 1kHz operation
use a time base sample wait, with 1kHz sampling
