Read temperature as part of the normal burst. This is not very costly since it
is part of the burst read in i2c and already read in spi.
It is meant to be used for imu heating.
The filter is set to 1Hz on temperature because of the inherent inertia of
heating systems.
Instead of just doing a static cast to the desired class, use a method
named "from". Pros:
- When we have data shared on the parent class, the code is cleaner in
child class when it needs to access this data. Almost all the data
we use in AP_HAL benefits from this
- There's a minimal type checking because now we are using a method
that can only receive the type of the parent class
We were able to read only the block of registers that are part of the
data output from accelerometer/gyroscope. In order to support reading
the external sensors we need support for reading a generic block of
registers.
This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.
We were previously leaking the AP_MPU6000_BusDriver if the
~AP_InertialSensor_MPU6000::detect*() failed. In order to avoid the
leak move the repeated code in a single private _detect() member that
receives everything as argument. Then this method takes ownership of the
objects.
By a adding a destructor to AP_InertialSensor_MPU6000 it becomes easier to
free the objects it takes ownership of.
The methods actually use the enum from AP_HAL::SPIDeviceDriver, so don't
declare a new one. The I2C implementation is empty; if we actually start
to use it we'd better move the bus abstraction to HAL.
This converts the MPU6000 driver to a frontend/backend structure, and
disables all other drivers. They will be progressively re-enabled as
each is converted
This private method allows to check whether the value written and
the posterior value readed are the same.
Should be used only for debuging purposes, for release versions use
_register_write instead.
this changes the sampling to 200Hz regardless of requested rate, and
it is downsampled inside num_samples_available() using a shift. This
gives better noise resistance in ArduPlane.
This patch also makes it possible to update the filter frequency while
running, which is very useful for bench testing with a vibration
source
use a single float return rather than two APIs.
This also changes the MPU6k driver to match the new 2.9 behaviour of
using the MPU6k sample timing instead of micros()
this lets the caller not need to know the underlying sample rate. They
just ask for what rate updates happen.
This also changes the MPU6k filtering to be less than half the sample
rate
sanity checking added to accelerometer calibration routine.
user feedback is sent using gcs_send_text_fmt instead of Serial.printf.
moved ins parameters to new eeprom number to avoid conflicts with older parameters.
other small changes including renaming of functions and parameters.
