Andrew Tridgell 6f6f89e5aa AP_InertialSensor: enable temperature sensor on LSM9DS0 
this allows for temperature calibration of the LSM303D in CubeBlack
and Pixhawk1

Andrew Tridgell b89c241329 AP_InertialSensor: use take_blocking instead of HAL_SEMAPHORE_BLOCK_FOREVER 
this makes for cleaner and smaller code as the failure case is not
needed

Peter Barker ef860db558 AP_InertialSensor: add floating point constant designators 2019-04-05 23:04:17 -07:00
Andrew Tridgell 81cd103073 AP_InertialSensor: probe for new v2 invensense IMUs 
also suppress LSM9DS0 whoami warnings, as these will now be common
with new IMUs

and make 20602 show up as a new devtype so we can distinguish it

Andrew Tridgell dff3ea416c AP_InertialSensor: allow for LSM9DS0 to be used on I2C 2019-03-10 09:03:06 +11:00
Lucas De Marchi c4e8aeb105 AP_InertialSensor: remove linux-only include 
We already include AP_HAL.h that includes the platform-agnostic gpio
header, which is all that this driver needs. This is an alternative
fix to #7794.

Lucas De Marchi caa4e3ee89 AP_InertialSensor: remove raspilot 2017-09-12 15:06:19 -07:00
Andrew Tridgell 49cc0965c0 AP_InertialSensor: separate handling of FIFO and non-FIFO sensors 
FIFO sensors produce data at a well known rate, but samples come in
bunches, so we can't use the system clock to calculate deltaT.

non-FIFO sensors produce data when we sample them, but that rate is
less regular due to timing jitter.

For FIFO sensors this changes makes us use a learned sample rate,
which allows for different clock speeds on sensor and system board.

For non-FIFO sensors we use the system clock to measure deltaT

the overall effect is a fix for sensors that produce samples at other
than the claimed datasheet rate.

Andrew Tridgell 25cd16a275 AP_InertialSensor: fixed LSM303D registered sample rate 
we are running the LSM303D at 1600Hz, and are sampling it at 1kHz. We
need to tell the AP_InertialSensor layer that samples will arrive at 1kHz

Andrew Tridgell 9e7e1b2f01 AP_InertialSensor: fixed merge conflicts with patches from Lucas 2016-11-09 17:08:06 +11:00
Lucas De Marchi 469efb00f6 AP_InertialSensor: save id for gyro and accel instances 
This allows each sensor to be uniquely identified in the system by using
either the index inside the backend or for those that use the Device
interface, to use the bus type, location, and device id.

We leave 16-bit for each sensor to be able to change its own
identification in future, which allows them to be changed in an
incompatible manner forcing a re-calibration.
 2016-11-09 17:08:05 +11:00
Lucas De Marchi ace61087a1 AP_InertialSensor: remove product_id 
We only leave the parameter there for backward-compatibility. However
product id on the inertial sensor is not much useful since it's only
kept for the first instance.

A better implementation per-gyro and per-accel is needed in order to
avoid problems with sensors taking the offsets configured for another
sensor.

Andrew Tridgell a5c5e033d2 AP_InertialSensor: fixed threading and locking in remaining backends

available

Andrew Tridgell 75ea8f3dc0 AP_InertialSensor: removed "have sample" logic from drivers 
the frontend has all the information it needs, so we can simplify the
drivers some more
 2015-11-16 17:57:35 +11:00
Andrew Tridgell 0e4bab74ba AP_InertialSensor: simplify sensor backends 
use common code for filtering and update, allowing each sensor driver
to be simpler and more consistent
 2015-11-16 17:57:35 +11:00
Lucas De Marchi 20c6ffc5e3 Replace use of UARTDriver::printf_P() with UARTDriver::printf() 
This also starts to show warnings on places that were already using
wrong printf format strings.
 2015-10-30 14:35:25 +09:00
Lucas De Marchi 6f4904189b Replace use of println_P() with println() 2015-10-30 14:35:22 +09:00
Lucas De Marchi 2c38e31c93 Remove use of PSTR 
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.

This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.

AVR-specific places were not changed.

Gustavo Jose de Sousa dfd671c54e AP_InertialSensor: Backend: add hook for new gyro sample arrival 
That hook will do common tasks for when new gyro raw sample is available.
 2015-10-22 16:53:10 +11:00
Gustavo Jose de Sousa e06627dfcb AP_InertialSensor: Backend: add hook for new raw accel samples 
That hook will eventually do necessary things when a new accelerometer raw
sample arrives (like calculating vibration levels).

Gustavo Jose de Sousa ac3a677626 AP_InertialSensor: remove param rotate_and_correct from publish functions 
Once that parameter is always false.
 2015-09-07 11:14:42 +10:00
Gustavo Jose de Sousa f946f48dce AP_InertialSensor: LSM9DS0: apply correction on each new sample 
These changes are for enabling unified accelerometer vibration and clipping
calculation. For that, we need the values "rotated and corrected" before they
are filtered and the calculation must be called as soon as a new sample arrives
as it takes the sample rate into account.

Thus, move code that applies "corrections" to be executed as soon as accel data
arrive and call _publish_accel() passing rotate_and_correct parameter as false.
Also, do the same for gyro so we can keep it consistent.
