Andrew Tridgell 483d19f44c AP_InertialSensor: apply stuck gyro fix to all IxM42xxx sensors
TDK has confirmed this applies to all IxM42xxx sensors

Andy Piper 7ca2a4da56 AP_InertialSensor: remove ICM42xxx defaults 2023-10-25 19:23:11 +11:00
Andrew Tridgell 0ebf9e7af5 AP_InertialSensor: pre-fetch instances for use in filter setup
we use the instance numbers during filter configuration to check if
fast sampling is enabled. We need to ensure these instance numbers
have been setup before the filtering functions get called

Andy Piper a9e0bf070c AP_InertialSensor: ensure indirect registers are not modified with sensors active on ICM-42688 2023-10-25 19:23:11 +11:00
Andy Piper da0b1402d3 AP_InertialSensor: add high-resolution reads for ICM45686
enable high-resolution support on all ICM4xxxx sensors
create INS_HIRES_SAMPLE mask
adjust high-resolution sampling for correct byte ordering and depth
correct high resolution scaling on 18bit ICM4xxxx IMUs
control highres via HAL_INS_HIGHRES_SAMPLE

Andrew Tridgell b6c9ac2569 AP_InertialSensor: added optional FIFO rate logging to invensensev3 driver
this is useful for tracking down and confirming the stuck gyro issue
on the ICM42688

Andrew Tridgell 792d8a4cb8 AP_InertialSensor: fix for ICM42688 stuck gyro issue
these undocumented bits in register 0x4d control the "adaptive full
scale range" mode of the ICM42688. The feature is enabled by default
but has a bug where it gives "stuck" gyro values for short periods
(between 1ms and 2ms):, leading to a significant gyro bias at longer
time scales, enough to in some cases cause a vehicle to crash if it is
unable to switch to an alternative IMU
