Randy Mackay 72dfe1127f AP_GPS: protect parameters from being accessed externally
backends become friends so they can continue to access parameters held in frontend
get_rate_ms made private because only used by frontend
Also moved static arrays higher in cpp file
2017-03-13 11:31:51 +11:00
Randy Mackay 3172657f26 AP_GPS: move constructor and complex accessors to cpp file
These functions are slightly long and make the .h file hard to read.  Also saves a small amount of flash space.

Randy Mackay 0066022a7f AP_GPS: check for valid instance in highest_supported_status

priseborough be0096e812 AP_GPS: Allow the user to specify the GPS time delay
If the user sets a non-zero value of the delay it will be used in preference over the default value for that GPS type.
If the GPS type is unknown and the parameter is set to zero, then a default delay of 1 sample period will be used (eg 200ms for 5Hz).

Andrew Tridgell bdc0630ccf AP_GPS: added all_configured() function
used for EKF to tell if gps_lag is valid
2017-01-27 16:57:42 +09:00
Andrew Tridgell 5d18f3a453 AP_GPS: added backend specific get_lag() function
the ublox7 and 8 seem to produce lower lag, around 120ms. Separately
we should also look at running these at 10Hz and see if that helps.

Lucas De Marchi ae53920e5b build: don't build examples with old build system
We currently check examples are buildable with waf which doesn't need

broken.

Michael du Breuil 9c4b3ec1e1 AP_GPS: Fix incorrect incrementing of last_baud rate
This is a revert of 7c3b8dceb which tried to start at index 0 of the
array of baudrates, however because of the way last_baud is used
this lead to a GPS always being reported as being 1 index off which
lead to users getting reports of baud rates that their GPS wasn't
configured for

Also renames last_baud to be current_baud as that is how it's
actuallly used and should reduce future confusion

And fixed some tabs/vs space issues around where the last_baud rate
was incremented.

Lee Hicks 51e8d8a294 AP_GPS: Don't send config blob to GPS unless AUTO_CONFIG=1

Lee Hicks 7c3b8dceb9 AP_GPS: Fixed GPS serial speeds starting at 1 instead of 0

Lucas De Marchi ff10d1136c AP_GPS: reorganize includes
Due to the way the headers are organized a single change in a
AP_GPS backend would trigger a rebuild for most of the files in the
project. Time could be saved by using ccache (since most of the things
didn't change) but we can do better, i.e.  re-organize
the headers so we don't have to re-build everything.

This makes internal headers internal and then other libraries only
depend on the AP_GPS.h header.

Michael du Breuil 4251ee0e4b AP_GPS: u-blox verify ublox settings
The ublox driver will now continuosly poll for the settings from the GPS and correct any that are found to be in correct.
This status is then reported to the arming library as an additional arming check, allowing the user to be sure that the
gps is correctly configured before using it. If a user has a GPS2 configured that is not present they will fail the arming
checks until after they have disabled the second GPS.

2 new parameters were introduced as well:
  -GPS_AUTO_CONFIG: Will not request any configuration packets to attempt to change them. (If the packet is recieved then
    a update will be sent to it, but in testing this scenario never occured. This is set to 1 or 0 to change the setting.
    (Defaults to 1 enabling auto config)
  -GPS_GNSS_MODE2: Behaves the same way as GPS_GNSS_MODE but only applies to the second GPS.

GPS drivers are now allowed 2 seconds of non responsiveness before being unloaded

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 1b07dabeb7 Replace prog_char and prog_char_t with char
prog_char and prog_char_t are now the same as char on supported

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 aa370fe758 Replace use of strcmp_P() with strcmp() 2015-10-30 14:35:09 +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 ec52df991c build: compile only the HAL files needed by the board
Instead of requiring every program to specify the HAL related modules,

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'.

Caio Marcelo de Oliveira Filho b5abab9d37 AP_GPS_GSOF: minor tweak to avoid warning
Fixes the issue of three unused variables, two of which were used in a
commented Debug() call.

To keep the convenient debug message (and the variable names for the
data bytes), this patch uncomment the debug call but wrap the variables
and the debug call around an ifdef for the local symbol
gsof_DEBUGGING. So by turning it on, the debug will already be in place.

The Debug() call was modified to actually compile and include the third
variable in the output.

Gustavo Jose de Sousa 67db430583 AP_GPS: 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.

Remove race condition on sending intial blob to the GPS, it was possible to send a blob that got the GPS configured enough to allow the autodetect to take over (and then some drivers like ublox would not finish sending the blob, which has potential details that the driver might have needed to send)

Limit the delay to checking for NMEA gps to only checking after all the available baud rates have been checked

Since a UBlox will actually report having DGPS (due to SBAS or RTCM data) actually report this as the highest supported mode

fix rate, which can confuse the EKF

Tom Pittenger 3544549cf4 AP_GPS: Allow switching primary GPS instance with 1 sat difference
Rapid switching between GPS receivers can cause real problems.
Switch if:
1) secondary GPS has 1 more satellite for at least 20 seconds
OR
2) secondary GPS has 2 more satellites for at least 5 seconds

Niels Joubert a5beef00d1 GPS: Official Swift Binary Protocol GPS Driver v3 for Piksi GPS
DRIVER FEATURES:
- All logic for RTK vs Normal now lives inside Piksi
- Supports observation uplink through telem radio
- Supports full SBP packet logging
- Reports high-rate green blinking to indicate RTK lock.
- Switchable to accept only Float or Integer RTK locks.

THIS REQUIRES PIKSI FIRMWARE v0.14 OR HIGHER
- Uses Piksi's new Pseudo-Absolute-Positioning mode
- Onboard Piksi must have Pseudo-Absolute mode enabled
- Ground Station Piksi must have a surveyed location in settings
- Ground Station Piksi must send its location to Onboard Piksi.

NEXT STEPS REQUIRED:
- EKF needs to take higher accuracy GPS into account
- EKF needs to take GPS RTK height into account
- GCS needs to support sending SBP observation packets
--- MAVProxy patch forthcoming
