Can STABILIZE and/or FBWA be added to Plane as an auxiliary function please?

ArduPlane Plane 4.0
10

OK. I have blundered along through the LUA landscape and come up with this script:

-- This script is to set FC mode to STABILIZE when the button is pushed
--  SRC 12JAN2020    
local button_number = 2 -- the button number we want to read, as defined in AP_Button
local button_active_state = true    --  the 'pressed' state of the button
local last_button_state
-- flight mode numbers for Plane
local MODE_STAB = 2
--local MODE_MANU = 0

function switchstabon()
  local button_new_state = button:get_button_state(button_number) == button_active_state

  if button_new_state ~= last_button_state then
    last_button_state = button_new_state  -- update latched state for edge detection
    if button_new_state then
      gcs:send_text(0, "LUA: Button 2 Pressed")
      vehicle:set_mode(MODE_STAB)
    else
      gcs:send_text(0, "LUA: Button Released")  -- switching back to manual is otherwise accomplished 
    end      
  end

  return switchstabon, 20  -- rescheduled loop every 20ms
end

return switchstabon()  -- run immediately before starting to reschedule

I don’t have any hardware to try this on currently. If somebody spots any syntax or logical errors please let me know :slight_smile:

Another alternative for this switching is to use the BUTTON functions to execute a script maybe. I can see that under RCn_OPTION there is the option for these to trigger scripts (300-307 for scripting1 to scripting8). Does anyone know how I link a script to the RCn_OPTION function? I assume it is just a script filename it executes but I have not been able to find what it might be in the documentation.

Having the ability to switch to stabilize with a straight button function in Plane would be much better. Can I add this as a feature request, please, developers? :smiley:
