Andrew Tridgell f9845c93b1 AP_InertialSensor: keep transfers nicely setup for DMA on stm32
this avoids using stack based bounce buffers which may not support DMA
on stm32

Andrew Tridgell 771cedca3d AP_InertialSensor: reduced number of SPI transfers
use cached copy of temperature in MPU6000 and MPU9250 to detect FIFO
error when possible

Andrew Tridgell 27605b0258 AP_InertialSensor: run invensese reg checking at low speed
config register read/write should be at low bus speed.

also change to check every 20 calls to reduce checking cost

Andrew Tridgell 9b4c588c09 AP_InertialSensor: adapt drivers for SPI-DMA capable systems
no longer need accumulate() transfers with SPI enabled DMA on stm32

Andrew Tridgell 28daddaaf2 AP_InertialSensor: don't use accumulate approach on Linux or I2C 2016-11-25 17:49:57 +11:00
Andrew Tridgell d9c8db7024 AP_InertialSensor: implement a new strategy for fast sampling
this moves to using a 1p filter on the high rate data, followed by
averaging down to 1kHz then a 2p filter to apply configured cutoff
frequency.

It also fixes the FIFO reset to not cause data corruption. We need to
disable all FIFO channels before doing the reset, and wait for the
FIFO to stop in the sensor.

Finally it moves sampling of the MPU6000 and MPU9250 into the main
thread. That significantly improves scheduling performance as we no
longer get long FIFO SPI transfers happening during other tasks. All
transfers happen at the start of the fast loop. That makes timing much
more predictable.

Thanks to Leonard and Paul for help with this design!

Lucas De Marchi 87c6d5da13 AP_InertialSensor: replace panic() with return
When blocking forever there's no reason to call panic later since it
will never going to be reached. This reduces binary size in a few bytes
since the message isn't required anymore.

Andrew Tridgell 6129b1abb6 AP_InertialSensor: wait forever for semaphore on startup
some boards take a silly amount of time to get semaphore on startup

Andrew Tridgell 216cf53922 AP_InertialSensor: handle FIFO overflow for MPU6k and 9250
this prevents temporary corruption of INS data on FIFO overflow

Andrew Tridgell 6af00027ab AP_InertialSensor: removed unused variables
thanks to Francisco for noticing

Andrew Tridgell 624178f3be AP_InertialSensor: added INS_FAST_SAMPLE parameter
this allows enable/disable of fast sampling per IMU, making
experimentation easier.

It also fixes the fast sampling to always average over 8 samples, and
fixes the 9250 to use the correct accumulator when not doing fast
sampling

Andrew Tridgell c0303ffe8a AP_InertialSensor: temporarily disable fast sampling
a problem has been found with the filtering with fast sampling on
ICM-20608 and MPU9250. Disable until it is solved.

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.

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.

reincluding the same emacs header in every file of the project.

Gustavo Jose de Sousa 1e99a7125c AP_InertialSensor: MPU9250: remove _register_write_check()

debug writes on registers.

Lucas De Marchi 057822b51c AP_InertialSensor: AuxiliaryBus: fix return value
We should return the number of bytes written/read, not 0 on success.
This number may be useful in some cases so return it.

While at it fix a simple wrong space in the header.

Lucas De Marchi 02a7fa5c2b AP_InertialSensor: MPU9250: use AP_HAL::Device abstraction
This makes MPU9250 be almost the same as MPU6000 driver. Work has been
done here to make than similar so it's easier to spot the differences.

José Roberto de Souza 0cbe99a862 AP_InertialSensor: MPU9250 I2C: Connect the auxiliary I2C bus to the main bus
Using MPU9250 over I2C we can connect the auxiliary bus where there is
a AK8963 and connect this bus to the main one, this way we don't need
any AuxiliaryBus infrastructure as we need with SPI and we can talk
with AK8963 as we would talk with a standalone AK8963.
