Lucas De Marchi fea084a596 Global: use ap_version.h 
This header is used by waf to contain the generated version macros,
particularly using the git hash. For waf it's better to be in a separate
header since it then can keep track of changes on it a trigger
recompilation.

For the make build system, a dummy ap_version.h file has been added in
the missing/ folder so both implementations can co-exist.

Andrew Tridgell b967140572 DataFlash: enable minimal file mode 
This adds a "minimal" dataflash mode with a board specific macro. The
QURT port uses this to avoid problematic system calls that are buggy
in the QURT RTOS

With some pending updates to QURT we may be able to remove some (or
all) of this

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.

Lucas De Marchi c74b1a660d DataFlash: remove DATAFLASH_NO_CLI 
This is not used anymore since the removal of AVR CPUs.
 2015-11-04 12:14:15 +11:00
Lucas De Marchi 1e839f97ed DataFlash: 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.
 2015-11-04 12:14:14 +11:00
Lucas De Marchi 0dfeae2556 DataFlash: remove checks for HAL_BOARD_APM2 and HAL_BOARD_APM1 2015-11-04 12:14:13 +11:00
Lucas De Marchi d2a259cef0 DataFlash: fix wrong printf format for printf 
"%S" is used for wide string, but we are passing a char*. Use lowercase
in this case to remove warnings like this:

libraries/AP_InertialSensor/AP_InertialSensor.cpp: In member function
'bool AP_InertialSensor::calibrate_accel(AP_InertialSensor_UserInteract*, float&, float&)':
libraries/AP_InertialSensor/AP_InertialSensor.cpp:620:61: warning:

                 "Place vehicle %S and press any key.\n", msg);
                                                             ^
 2015-10-30 14:35:42 +09:00
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.
 2015-10-30 14:35:32 +09:00
Lucas De Marchi 1b07dabeb7 Replace prog_char and prog_char_t with char 
prog_char and prog_char_t are now the same as char on supported
platforms. So, just change all places that use them and prefer char
instead.

AVR-specific places were not changed.
 2015-10-30 14:35:30 +09:00
Lucas De Marchi b52d1cfabb DataFlash: remove DataFlash.Log_Write_Message_P() 2015-10-30 14:35:29 +09:00
Lucas De Marchi 4ab9821624 Replace use of Log_Write_Message_P() with Log_Write_Message() 2015-10-30 14:35:28 +09:00
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.
 2015-10-30 14:35:25 +09:00
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 1336d621be Replace use of strcpy_P() with strcpy() 2015-10-30 14:35:12 +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.

Also reference log numbers by their list index to accomodate log number
wrapping in DataFlash_File
 2015-10-21 10:50:32 +11:00
Lucas De Marchi 19b31ccff1 DataFlash: remove check for max compass instances 
For all supported boards the maximum number of instances is 3.
 2015-10-21 10:05:18 +11:00
Lucas De Marchi d83609b24c DataFlash: remove check for max BARO instances

 2015-10-21 10:05:17 +11:00
Lucas De Marchi f99d64e621 DataFlash: remove check for max INS instances 
For all supported boards the maximum number of instances is 3.

Caio Marcelo de Oliveira Filho b028219c94 DataFlash: remove unnecessary includes from example 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.
 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 709204c01d DataFlash: 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.

modified by the startup code and if we log the parameters too early we
will be recording the wrong value.

Andrew Tridgell 63910bf8cd DataFlash: work around a NuttX bug 
the seek offset of files can get badly mucked up when it crosses
cluster boundaries. We need to fix this in NuttX, but meanwhile this
works around the bug. It seems that doing a lseek(fd, 0, SEEK_CUR)
fixes the seek offset in the file.

The bug seems to first happen at an offset of 315392. It also
doesn't happen every time - it is more likely to happen on the first
log download after booting

Andrew Tridgell cb23298384 DataFlash: try to keep dataflash writes aligned 
also rename lastlog.txt to LASTLOG.TXT as NuttX seems to get less
corruption with VFAT filenames that don't need uppercase mappings
 2014-01-14 12:46:26 +11:00
Randy Mackay a53d1075ec DataFlash: add EnableWrites method 
This method allows temporarily suspending writes to the dataflash which
will be used in ArduCopter to ensure no messages are written while the
copter is disarmed
 2014-01-07 22:43:44 +09:00
Andrew Tridgell 4519aa8867 DataFlash: only fsync every 10 seconds 
prevents too much work in SITL

this copes with dataflash wrapping
 2013-12-17 11:51:36 +11:00
Andrew Tridgell e6bafa2d8f DataFlash: added structures to Init() of dataflash

trying to create it a 2nd time.
