Gustavo Jose de Sousa 46774136a6 AP_Compass: standardize inclusion of libaries headers 
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.

is related to by using the task's name rather than using the number.
 2015-09-01 20:22:18 +10:00
Gustavo Jose de Sousa 2e6074c108 AP_Scheduler: use designated initializers for tasks structs

same case for the y position
add get_angle_to_target method
get_angle_to_target replaces pixel to position calculations

Stewart Loving-Gibbard c5f70d22c5 AP_RSSI: Adding RSSI library for reading various kinds of RSSI, with the possibility of adding more. 
* Retains ability to read from Analog Pin
* Adds ability to read RSSI from PWM channel value as is done in OpenLRSng, EazyUHF, and various other LRS.
* Handles any type of RSSI that provides RSSI values inverted - i.e. when the low value is the best signal and the high value is the worst signal.
* Has different key names from all existing RSSI parameters to provide for a clean break and easier distinguishing.

Lucas De Marchi c66c9c41f2 AP_Compass: HMC5843: be agnostic to I2C bus 
Like was done to inertial AK8963 and inertial sensor move the decision
regarding the I2C bus to the caller. We don't allow changing the address
because apparently HMC5843 doesn't support different addresses.

Changing only the bus could be more easily done but this prepares the
ground for using HMC5843 on an AuxiliarBus.

The need for a more generic abstraction is evidenced by this commit: a
"SerialBus" in AP_HAL would be a nice addition rather than letting each
driver to provide its own. However the methods are a little bit
different from what we have in AK8963. It's safer to do the simple
conversion now and later on to add the abstraction changing everybody to
use it.

This way we don't mix two different conditionals: settling and data validation.

Lucas De Marchi f61386ae43 AP_Compass: HMC5843: release the lock before read 
read() calls accumulate() which takes the lock by itself so we must
release it like we were doing before 669ae26 ("AP_Compass: encapsulated
calibration in HMC").

Lucas De Marchi a5df93bf10 AP_Compass: AK8963: be agnostic to I2C bus/address 
This decision is better made by the caller rather than polluting the
driver with board-specific details.

Lucas De Marchi d92c2ac9f5 AP_Compass: pass backend instead of pointer to function 
Just like was done for inertial sensor, different detect() functions
might need different arguments and passing a pointer to function here is
cumbersome. For example, it forces to have a method like "detect_i2c2"
rather than allowing hal.i2c2 to be passed as parameter.

Lucas De Marchi c66800dfec AP_InertialSensor: add singleton interface 
In order to allow other libraries to use the InertialSensor we need a
way to let them to get the only instance of InertialSensor. The
conventional way to do a singleton would be to let the constructor
private and force it to be instantiated from the get_instance() method.

Here however we just call panic() on the constructor if there's already
an instance alive. This allows us to let the vehicles as is. Later we
can change it so they call the get_instance() method instead.

Lucas De Marchi 565c18603d AP_InertialSensor: MPU6000: export auxiliary bus 2015-08-28 12:39:08 +10:00
Lucas De Marchi caae933c28 AP_InertialSensor: Add support for auxiliary buses 
Add an AuxiliaryBus class that can be derived for specific
implementations in inertial sensor backends. It's an abstract
implementation so other libraries can use the auxiliary bus exported. In
order for this to succeed the backend implementation must split the
initialization of the sensor from the actual sample collecting, like is
done in MPU6000.

When AP_InertialSensor::get_auxiliary_bus() is called it will execute
following steps:
	a) Force the backends to be detected if it's the first time it's
	   being called
	b) Find the backend identified by the id
	c) call get_auxiliary_bus() on the backend so other libraries can
	   that AuxiliaryBus to initialize a slave device

Slave devices can be used by calling AuxiliaryBus::request_next_slave()
and are owned by the caller until AuxiliaryBus::register_periodic_read()
is called. From that time on the AuxiliaryBus object takes its ownership.
This way it's possible to do the necessary cleanup later without
introducing refcounts, that we don't have support to.

Between these 2 functions the caller can configure the slave device by
doing its specific initializations by calling the passthrough_*
functions. After the initial configuration and register_periodic_read()
is called only read() can be called.

Lucas De Marchi 7d9579c5d8 AP_InertialSensor: identify backend with ID 
Identify backend with an id, allowing other libraries to connect to
them. This is different from the _product_id member because it
identifies the sensor, not the board the sensor is in, which is
meaningless for our use case.

Lucas De Marchi 22c787058e AP_InertialSensor: allow to split detection and initialization 
This allows backends to have a separate detection and initialization
logic. It doesn't change any backend yet and with the current code
there's no change in behavior either. This only allows
AP_InertialSensor::_detect_backend() to be called earlier so
AP_InertialSensor object can be used by other libraries. If it's not
called, later on AP_InertialSensor::init() will detect and start all
backends.

Lucas De Marchi f7954ee885 AP_InertialSensor: MPU6000: allow to read generic block 
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.

We're reading the sensor data available in MPU6000 so name the method
accordingly, which is also the same name used in MPU9250.
