AC_WPNav: fixup max speed acceleration
AC_WPNav: simplify the initialisation of poscontrol's max speed
Changed at Leonard's request to keep things simpler
Respond to 0x10 when the rx is controlling bandwidth, else respond only to 0x00
but in this case never exceed a max number of consecutive frames.
Always respond to polling and if necessary send a null frame.
moved delay check after get_telem_data() to account for scheduler time
align incoming to outgoing crc
allow the boot-time recording state to be configured
only process events on state transitions. Simplifies logic and debugging.
support regular Split 2s
allow menu enter/exit in 5-key mode
match betaflight with 5-Key OSD which requires an "enter" key
This fixes high stack usage in the RCIN thread when it notifies the
GCS of a new RCIN protocol. The problem is severe when signing is
enabled, as signing adds over 500 bytes to stack cost of sending a
mavlink msg
fixes issue #13615
Lowering the sleep time when no scripts are pending, causes starting a
REPL session to respond much faster (this cuts the latency from up to 10
seconds to 1 second before the session is ready to start).
Also lowers the default scripting debug level to hide the statustext
from users, as in the general case this is just a spammy message if it
occurs, and we should be finding better reporting bits to get this to
the user.
when GPS primary switches we were using a position which had not been
corrected for antenna offset. This was used for calculating the reset
for sensor change.
This fixes that (trivial fix) and also fixes a similar issue on
position reset
