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.

José Roberto de Souza c3dae6fcec AP_InertialSensor: MPU9250: Remove methods not used anymore
Those methods were used by AK8963 before it started to use auxiliary bus.

José Roberto de Souza 206f0fb773 AP_InertialSensor: MPU9250: Add BusDriver abstraction
This adds a similar abstraction to the one in MPU60XX so it's possible to use
MPU9250 in other bus. The I2C implementation will come later.

Lucas De Marchi 94d01934f7 AP_Baro: MS5611: reduce OSR to 1024
This is the same change as done in PX4:

	This reduces self-heating of the sensor which reduces the amount
	of altitude change when warming up. Apparently some individual
	sensors are severely affected by this.

	Unfortunately it raises the noise level, but Paul is confident
	it won't be a significant issue.

Andrew Tridgell ea5cd99651 RC_Channel: use is_bounded_int32() 2015-11-11 13:45:09 +11:00
Andrew Tridgell 090c02e6bd AP_Common: rename is_bounded() to is_bounded_int32() and make inclusive
we will probably want float versions in future, and inclusive is
better for the RC_Channel case

around the TRIM.

The util object may be used by all other objects so we need to
instantiate it as earlier as possible.

scanf-like functions.

Lucas De Marchi 821814007e AP_Common: add scanf format macro
Add a macro to annotate functions that act like scanf.  Calling the
printf format macro as FORMAT was bad as can be seen now. Later we need
to rename it to FMT_PRINTF.

Lucas De Marchi c66c61180a AP_HAL_Linux: rework PWM_Sysfs
This include some minor changes on all methods of PWM_Sysfs:

  - Sort headers
  - Add code inside Linux namespace rather than just use the namespace
  - Declare a union pwm_params, that's only used to calculate at compile
    time the maximum stack space we need in our methods: this is a bit
    safer for future extensions
  - Standardize error messages to include the useful params first and
    then the error message
  - Remove log message from hot path
  - Don't abuse macros for checking error - convert the SNPRINTF_CHECK
    macro into proper code, ignoring errors for not enough space since
    they can't happen
  - Fix call to read_file() passing uint8_t for "%u" in get_period()
  - Fix passing char** instead of char* to write_file() in set_polarity()
  - Use strncmp() instead of strncasecmp() since the kernel API uses
    lowercase.
  - Add comments on the 2 main methods of this class

Paul Riseborough 577670ccee AP_NavEKF2: Reduce memory required by 6KB when running at 400Hz
Down-sample the IMU and output observer state data to 100Hz for storage in the buffer.
This reduces storage requirements for Copter by 75% or 6KB
It does not affect memory required by plane which already uses short buffers due to its 50Hz execution rate.
This means that the EKF filter operations operate at a maximum rate of 100Hz.
The output observer continues to operate at 400Hz and coning and sculling corrections are applied during the down-sampling so there is no loss of accuracy.

Lucas De Marchi 825d10c81a Filter: remove filter with double type
We are currently not using LowPassFilter2p<double> and it just generates
a lot of warnings on PX4 while instantiating it due to implicitly
promoting float to double:

Paul Riseborough 3d8e74df26 AP_NavEKF2: Don't switch magnetometers when on the ground or just started
Large magnetometer innovations on the ground could be caused by factors that will disappear when flying, eg:

a) Bad initial gyro bias
b) External magnetic field disturbances (adjacent metal structures, placement of hatches with magnets, etc)

To avoid unnecessary switches, we inhibit switching until off-ground and when sufficient time has lapsed from power on to learn gyro bias offsets.
