James O'Shannessy 1794eefd33 AP_Mission: Fixes crash in copter when uploading MAV_CMD_NAV_LAND with NaN as p4 
Uploading a mission created in QGC with MAV_CMD_NAV_LAND (instead of return to launch) results in crash of copter because p4 is not set.

auturgy 9aeb456a1d AP_Mission: NFC Correct some comments

Andrew Tridgell 7c49723f19 AP_Mission: added continue after land mission option 
this allows for option to continue a mission after a landing is
complete. The default in copter was to continue, so adding this
option makes copter not continue by default. Plane already disarmed on
land complete.

Peter Barker aae524b9d5 AP_Mission: add sanity check that 16-bit commands aren't stored_in_location 
This is a rather confusing problem when it happens during development,
so a sanity check is good.  What you see in dev is that your latitude
gets corrupted between when you store and retrieve it, with no warnings
that you're doing something wrong.

Andrew Tridgell a3e07f66a1 AP_Mission: removed create() method for objects 
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco

Gustavo Jose de Sousa d281067bcc waf: make example binaries be placed in 'examples' dir 
This commit makes examples' wscripts use ardupilotwaf.example() instead of
ardupilot.program().

Lucas De Marchi 3941bb7347 AP_Mission: remove checks for HAL_BOARD_APM2 and HAL_BOARD_APM1 2015-11-04 12:14:12 +11:00
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.

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.

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 118de8d01f AP_Mission: remove unnecessary includes from example 2015-10-21 09:16:11 +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'.
