Andy Piper 36878e9b3c AP_InertialSensor: Allow all filter frequencies to be 16bit. 2019-06-06 17:09:17 +10:00
Andy Piper fff81a2163 AP_InertialSensor: Make sure the LPF output is used by the notch input. 2019-06-06 17:09:17 +10:00
Andy Piper 18d403c3ac AP_InertialSensor: Rework notch filter allocation and sampling 
https://github.com/ArduPilot/ardupilot/issues/11346

Allocate a notch filter per-IMU.
Update the notch filters in the backend at the sensor sample rate.
Allow raw logging of post-filtered gyro and accel values.

Andrew Tridgell 893b49d145 AP_InertialSensor: disable register checking in invensensev2 driver 
register checking doesn't work for the banked registers used in the
invensensev2 register layout. It ends up setting the wrong register
value in some cases, which can either cause the sensor to stop working
or in the worst case give bad data

Lucas De Marchi 49d08ba72a Global: remove minlure 
Minlure is a port of ArduPilot to Minnow Board connected to daughter
board. Very few of those were produced and nobody is flying with it.

It served its purpose and all the the improvements to ArduPilot remain
regardless of it not being supported anymore. Now it's just adding
maintenance work with no clear benefit, so pull the plug.

See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Andrew Tridgell bfd8d151c8 AP_InertialSensor: lower slave rate with fast sampling 
On an invensense IMU with fast sampling we need to lower the slave
sample rate for slave sensors such as the built-in AK8963 compass on a
MPU9250.

The slave rate is set as a multiple of the main rate, so it needs to be
much lower for fast sampling. If we leave it high then it greatly
impacts on IMU sample rate.

Without this change a MPU9250 with fast sampling and a compass enabled
will give a gyro rate of around 7200Hz. With this change it gets 7760Hz

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 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!
