Caio Marcelo de Oliveira Filho 6e7b73610d waf: add waf support 2015-12-03 07:54:30 +11:00
Caio Marcelo de Oliveira Filho 5b06924779 AP_OpticalFlow: use millis/micros/panic functions 2015-11-20 12:33:19 +09:00
Andrew Tridgell 8f4ce7f20b build: removed all nocore.inoflag files 
these were APM2 specific

Lucas De Marchi 0d95a9c41d AP_OpticalFlow: reduce lock region 
Release the lock as soon as we can.
 2015-11-05 16:12:03 +09:00
Lucas De Marchi 70edf31ca6 AP_OpticalFlow: make error path common 2015-11-05 16:12:00 +09:00
Lucas De Marchi 7b726d824d AP_OpticalFlow: remove num_errors increment due to busy bus 
num_errors should be used to detect bad bus transfers, not if we
actually read something. Since we are using i2c_sem->take_nonblocking()
failing here is more likely if the bus is shared.
 2015-11-05 16:11:58 +09:00
Lucas De Marchi 41ddb67712 AP_OpticalFlow: pack struct passed to I2C layer 
We pass "sizeof(i2c_integral_frame)" to hal.i2c->readRegisters(). Since
we have a padding in i2c_integral_frame we actually read 3 bytes more
than we should. Add PACKED to the struct so this is fixed.

i2c_frame doesn't have a padding (or hole) so there isn't this problem,
but since it's also used to calculate the frame size, use PACKED there
too.

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() 
This also starts to show warnings on places that were already using
wrong printf format strings.
 2015-10-30 14:35:25 +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 de98ec7c1a AP_OpticalFlow: fix build of example for PX4 2015-10-21 09:16:12 +11:00
Caio Marcelo de Oliveira Filho ae9bc62e84 AP_OpticalFlow: remove unnecessary includes from example 2015-10-21 09:16:12 +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'.

Gustavo Jose de Sousa f32c4ceda9 AP_OpticalFlow: 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.

Pat Hickey 26ba391cd4 AP_OpticalFlow_ADNS3080: has private AP_Semaphore* _semaphore 
Semaphore can be null, handled correctly if it is. Rather than check for

before using it. More general and flexible.
