Lucas De Marchi 180359d6dd AP_Math: fix unit test 
For ROTATION_ROLL_90_PITCH_68_YAW_293 consider the angles as 90, 68.8
and 293.3 degrees to pre-calculate rotation. This matches the rotation
matrix used in code.

While at it, check not only the values are close enough but also the
length of the vector.
 2015-12-30 20:22:28 -02:00
Lucas De Marchi ba3325ffd3 AP_Math: rename rotation 
The rotations are supposed to follow the name of the enum, in order. The
ROTATION_YAW_293_PITCH_68_ROLL_90 was added with the name of an
intrinsic 321 rotation, but the matrix is actually a 123 rotation,
following the other rotations already present.

Change the name to follow the other names.

Lucas De Marchi e0a0514c79 AP_Math: turn MIN/MAX macros into inline functions 
The problem with the current MIN/MAX macros is that they evaluate twice
the arguments. For example, these cases provide unintended results:

	// a is incremented twice
	a = MIN(a++, b);
	// foo() with side-effects
	a = MIN(foo(), b);

The alternative implementation here was provided by Daniel Frenzel using
template function. It doesn't have type safety as std::min and std::max,
but adding type safety would mean to check case by case what would be a
reasonable type and add proper casts. Here the arguments for MIN and MAX
can have different types and the return type is deduced from the
expression in the function.

Inspecting the current callers no place was found with the unintended
results above, but some in which now we don't calculate twice the
parameters will benefit from this new version. Examples:

	float velocity_max = MIN(_pos_control.get_speed_xy(), safe_sqrt(0.5f*_pos_control.get_accel_xy()*_radius));

	float acro_level_mix = constrain_float(1-MAX(MAX(abs(roll_in), abs(pitch_in)), abs(yaw_in))/4500.0, 0, 1)*ahrs.cos_pitch()

	accel_x_cmss = (GRAVITY_MSS * 100) * (-(_ahrs.cos_yaw() * _ahrs.sin_pitch() / MAX(_ahrs.cos_pitch(),0.5f)) - _ahrs.sin_yaw() * _ahrs.sin_roll() / MAX(_ahrs.cos_roll(),0.5f));

	track_leash_slack = MIN(_track_leash_length*(leash_z-track_error_z)/leash_z, _track_leash_length*(leash_xy-track_error_xy)/leash_xy);

	RC_Channel_aux::move_servo(RC_Channel_aux::k_sprayer_pump, MIN(MAX(ground_speed * _pump_pct_1ms, 100 *_pump_min_pct),10000),0,10000);
 2015-12-01 16:28:18 -02:00
Lucas De Marchi 2591261af6 Global: rename min and max macros to uppercase 
The problem with using min() and max() is that they conflict with some
C++ headers. Name the macros in uppercase instead. We may go case by
case later converting them to be typesafe.

Changes generated with:

	git ls-files '*.cpp' '*.h' -z | xargs -0 sed -i 's/\([^_[:alnum:]]\)max(/\1MAX(/g'
	git ls-files '*.cpp' '*.h' -z | xargs -0 sed -i 's/\([^_[:alnum:]]\)min(/\1MIN(/g'

Lucas De Marchi fb28f426da AP_Math: remove check for AVR CPUs 
Remove the checks for HAL_CPU_CLASS > HAL_CPU_CLASS_16 and
HAL_CPU_CLASS >= HAL_CPU_CLASS_75. Corresponding dead code will be
removed on separate commits.

Lucas De Marchi c7871d1bca AP_Math: remove checks for HAL_BOARD_APM2 and HAL_BOARD_APM1 2015-11-04 12:14:12 +11:00
Lucas De Marchi 5244559010 Minimize AP_Progmem.h includes 
Most of AP_Progmem is already gone so we can stop including it in most
of the places. The only places that need it are the ones using
pgm_read_*() APIs.

In some cases the header needed to be added in the .cpp since it was
removed from the .h to reduce scope. In those cases the headers were
also reordered.

Lucas De Marchi 20c6ffc5e3 Replace use of UARTDriver::printf_P() with UARTDriver::printf()

wrong printf format strings.

Lucas De Marchi 6f4904189b Replace use of println_P() with println() 2015-10-30 14:35:22 +09:00
Lucas De Marchi 831d8acca5 Remove use of PROGMEM 
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:

    git grep -l -z PROGMEM | xargs -0 sed -i 's/ PROGMEM / /g'
    git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'

The 2 commands were done so we don't leave behind spurious spaces.

AVR-specific places were not changed.
 2015-10-30 14:35:16 +09:00
Lucas De Marchi 2c38e31c93 Remove use of PSTR 
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.

This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.

AVR-specific places were not changed.

Caio Marcelo de Oliveira Filho 5020db4481 AP_Math: remove unnecessary includes 
Remove unnecessary includes, in particular the includes for specific
boards. The list of libraries for 'polygon' example was updated so that
the example compiles again.
 2015-10-21 09:16:09 +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.
 2015-10-21 09:16:07 +11:00
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'.

Valmantas Palikša d4daf19151 AP_Math: Move simple math function implementations to header for better 
compile time optimization

Functions like sq() are better moved to the header file as inline.
Compiler can then optimize these out when used in code, this saves cpu
cycles with stack push, pop during function calls.

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.
