This commit adds:
- New driver for SBPv2
--- Support Piksi Multi, Swift Navigation's multi-band multi-constellation GPS
--- Proper parsing of SBP flags
--- Instant response to Piksi status changes (no more timeouts)
--- Support for Piksi Multi as a Single-Point-Positioning GPS or only onboard GPS
--- Incorporates horizontal and vertical accuracy estimates, and vdop.
- Updates driver for SBPv0
--- Continue support for previous Piksi
- Dispatches correct driver based on SBP version.
This includes these changes:
RATE_MS, RATE_MS2 parameter description Range minimum reduced to 50
_blend_health_counter is reset to 0 if blending is disabled
GPS_MAX_RECEIVERS is replaced with GPS_BLENDED_INSTANCE where appropriate
simplify all_consistent functions check of number of receivers
calc_blended_weights fix for initial check of how many receivers we have
remove unnecessary setting of GPS last time when blending fails
remove RebootRequired from AUTO_SWITCH param description
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
highest_supported_status will always return FIX_3D for blended or invalid instance
setHIL_Accuracy checks instance is 2 or less
send_mavlink_gps2_raw uses num_instances variable directly to avoid confusion with num_sensors
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).

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.
All GPS types will recieve startup up blob config. For
some recievers this will cause them to hang. This commit
only allows sending of blobs if AUTO_CONFIG=1. Fixes#2622
The new function can deal with a variable number of function parameters.
Additionally, I renamed the functions to norm(), because this is the
standard name used in several other projects.
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.
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
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.
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.
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.
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.
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.
Ublox 7 and 8 seires use a UBX-CFG-GNSS message to enable satellite constellations. The default value does not enable any additional ones, and any constellations the reciever doesn't report knowing about are not configured.
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
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
