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
Fixes https://github.com/diydrones/ardupilot/pull/2320
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
