Optionally format distance as meters/kilometers or feet/miles based on overal distance. For metric, distance will be displayed as:
0-999m: display meters
1000-9999m: display as kilometers with 2 decimals (ie. 1.23K)
10000m and above: display as kilometers with 1 decimal (ie. 10.5K)
Similar for imperial units except that will display feet up to 1 mile (5280ft), miles with 2 decimals from 1-9.99 miles, and with 1 decimal over 10 miles.
Configured with `osd_dynamic_distance_units = OFF | ON`. If off (the default) then the behavior is unchanged and the distance will be only displayed in meters or feet depending on the units selection.
There are currently no OSD font symbols for kilometers or miles so "K" and "M" are used at this time.
Moved vtxtable frequency mode implementation into `vtx_common.c`.
This makes the implementation available for all vtx types and allows
for some code deduplication (see point below)
Removed band and channel tracking from tramp and rtc6705.
The hardware underlying both only support frequency mode and
the tracking is now done in `vtx_common.c` using the new factory flag.
Deleted vtxStringXXX. to continue supporting builds without
`USE_VTX_TABLE`, new infrastructure was created in
`drivers/vtx_table.c`, which loads fixed tables into vtxTableXXX
when built witout `USE_VTX_TABLE`. Individual vtx implementations no
longer need to load any band/channel tables. They only need to load
their individual power tables when built without `USE_VTX_TABLE`.
Additionally this allows for the next point:
Fully integrated vtxTableXXX and removed the old and no longer needed
indirection of frequency and power tables in `vtxDevice_t`.
Removed VTX_SETTINGS_* constants from `vtx_common.h` and replaced them
with the vtxtable equivalent.
rtc6705 implementation now uses power values from vtxtable instead of
using indices directly. It also stops using index 0. This makes it
consistent with other vtx implementations and is more user configurable.
It also cleans up `telemetry\srxl.c` which had to have a special case for rtc6705.
Finally, frequency entries in the vtxtable can now be marked as empty
by setting their frequency to 0. Betaflight will never allow a blocked
channel to be selected. This is useful for vtxtable index mode
(FACTORY flag set) where manufacturer-defined bands can be truncated
to ensure compliance with local laws and regulations.
Allows reordering OSD post-flight statistics without affecting the storage bit position and requiring Configurator changes. Previously the display order was one and the same with the enabled flag bit position. Additionally this ordering was also used by the configurator. So if the ordering was changed then the user settings would become corrupted (different stats would be enabled/disabled). Also the Configurator had an internal representation that had to match the definition enumeration otherwise the flags returned when saving would also set the wrong bits.
Now the definition remains constant and unchanging. The bit positions for the enable flag will not be changed. A separate array defines the presentaion order of the permanent stats ID's.
Added the display order to MSP to allow the configurator to also present the stats in the same order displayed in the firmware.
