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:

libraries/Filter/LowPassFilter2p.cpp: In instantiation of
	'T DigitalBiquadFilter<T>::apply(const T&, const DigitalBiquadFilter<T>::biquad_params&) [with T = double]':
libraries/Filter/LowPassFilter2p.cpp:86:41:   required from 'T LowPassFilter2p<T>::apply(const T&) [with T = double]'
libraries/Filter/LowPassFilter2p.cpp:98:16:   required from here
libraries/Filter/LowPassFilter2p.cpp:20:82: warning: implicit conversion from 'float' to 'double' to match other
	operand of binary expression [-Wdouble-promotion]
     T delay_element_0 = sample - _delay_element_1 * params.a1 - _delay_element_2 * params.a2;
                                                                                  ^

Caio Marcelo de Oliveira Filho d32207008d Filter: remove unnecessary includes from examples 2015-10-21 09:16:10 +11:00
Caio Marcelo de Oliveira Filho ec52df991c build: compile only the HAL files needed by the board 
Instead of requiring every program to specify the HAL related modules,
let the build system do it (in practice everything we compiled depended
on HAL anyway). This allow including only the necessary files in the
compilation.

Caio Marcelo de Oliveira Filho 2e464a53c2 AP_HAL: make code not depend on concrete HAL implementations 
The switching between different AP_HAL was happening by giving different
definitions of AP_HAL_BOARD_DRIVER, and the programs would use it to
instantiate.

A program or library code would have to explicitly include (and depend)
on the concrete implementation of the HAL, even when using it only via
interface.

The proposed change move this dependency to be link time. There is a
AP_HAL::get_HAL() function that is used by the client code. Each
implementation of HAL provides its own definition of this function,
returning the appropriate concrete instance.

Since this replaces the job of AP_HAL_BOARD_DRIVER, the definition was
removed.

The static variables for PX4 and VRBRAIN were named differently to avoid
shadowing the extern symbol 'hal'.

dgrat 58e2ac4e56 Filter: Template implementation for <Filter> 
There are implementations for float, Vector2f and Vector3f for the Low
Pass Filter and the *2p filter.  I tried to implement these filters
with one common template implementation.  This implementation saves
some lines of code and reduced the redundancy.  One could save even
more code if the currently overloaded isinf/isnan functions and checks
can be removed.

Gustavo Jose de Sousa a1af0c2051 Filter: 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.

James Bielman 4fa7bb1486 Add AVR compatibility header for missing math.h definitions. 
- Define float versions of math functions to the double versions
  on AVR (eg. #define sinf sin).
- These macros appear to be missing in older versions of avr-libs.
- Include AP_Math.h rather than math.h to get these definitions.

James Bielman 5631f865b2 Update floating point calculations to use floats instead of doubles. 
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.
