5 position rotary switch that act as Magneto switch integration

[m4biz]

Hi.
I'm looking for the best way to integrate a 5 position rotary switch that act as Magneto switch inside my DIY cockpit.

I'm just using Arduino and Air Manager.
Any idea?
Thanks in advance

Use the pre made hardware function?

Personal sample (X-Plane only) :

Code: Select all

function pr_starter(starter_state)
	xpl_dataref_write("sim/cockpit2/engine/actuators/ignition_key","INT[8]", {starter_state}, 0)
	if starter_state == 4 then
		xpl_command("sim/starters/engage_start_run")
		xpl_command("sim/operation/auto_start")
	end
end

hw_sw_starter	= hw_switch_add("MAGNETOS KEY", 5,
								pr_starter)
if (hw_switch_get_position(hw_sw_starter) ~= nil) then
	key_pos = hw_switch_get_position(hw_sw_starter)
	xpl_dataref_write("sim/cockpit2/engine/actuators/ignition_key","INT[8]", key_pos, 0)
end

Ralph's suggested sample for multiple sims :

Code: Select all

prop_engine  = user_prop_add_integer("Engine number", 1, 4, 1, "Choose the engine number for this switch")
prop_magneto = user_prop_add_enum("Magneto order", "LEFT/RIGHT/BOTH,RIGHT/LEFT/BOTH", "LEFT/RIGHT/BOTH", "Choose the order of your magnetos")
prop_lastpos = user_prop_add_enum("Last position", "Starter,Primer", "Starter", "Choose the function of the last position")

local engn = user_prop_get(prop_engine)
local mago = fif(user_prop_get(prop_magneto) == "LEFT/RIGHT/BOTH", 0, 1)

function starter_pressed()
    xpl_command("sim/starters/engage_starter_" .. engn, 1)
    fsx_event("MAGNETO" .. engn .. "_START")
    fs2020_event("MAGNETO" .. engn .. "_START")
end

function starter_released()
    xpl_command("sim/starters/engage_starter_" .. engn, 0)
end

if user_prop_get(prop_lastpos) == "Primer" then
    hw_button_add("Starter button", starter_pressed, starter_released)
end

hw_switch_add("Magneto switch", 5, function(position, direction)

    if position == 0 then
        xpl_command("sim/magnetos/magnetos_off_" .. engn)
        fsx_event("MAGNETO" .. engn .. "_OFF")
        fs2020_event("MAGNETO" .. engn .. "_OFF")
    elseif position == 1 then
        if mago == 0 then
            xpl_command("sim/magnetos/magnetos_left_" .. engn)
            fsx_event("MAGNETO" .. engn .. "_LEFT")
            fs2020_event("MAGNETO" .. engn .. "_LEFT")
        else
            xpl_command("sim/magnetos/magnetos_right_" .. engn)
            fsx_event("MAGNETO" .. engn .. "_RIGHT")
            fs2020_event("MAGNETO" .. engn .. "_RIGHT")
        end
    elseif position == 2 then
        if mago == 0 then
            xpl_command("sim/magnetos/magnetos_right_" .. engn)
            fsx_event("MAGNETO" .. engn .. "_RIGHT")
            fs2020_event("MAGNETO" .. engn .. "_RIGHT")
        else
            xpl_command("sim/magnetos/magnetos_left_" .. engn)
            fsx_event("MAGNETO" .. engn .. "_LEFT")
            fs2020_event("MAGNETO" .. engn .. "_LEFT")
        end
    elseif position == 3 then
        if user_prop_get(prop_lastpos) == "Starter" then
            xpl_command("sim/starters/engage_starter_" .. engn, 0)
        else
            xpl_command("sim/fuel/fuel_pump_" .. engn .. "_prime", 0)
            fsx_event("TOGGLE_PRIMER" .. engn)
            fs2020_event("TOGGLE_PRIMER" .. engn)
        end
        xpl_command("sim/magnetos/magnetos_both_" .. engn)
        fsx_event("MAGNETO" .. engn .. "_BOTH")
        fs2020_event("MAGNETO" .. engn .. "_BOTH")
    elseif position == 4 then
        if user_prop_get(prop_lastpos) == "Starter" then
            xpl_command("sim/starters/engage_starter_" .. engn, 1)
            fsx_event("MAGNETO" .. engn .. "_START")
            fs2020_event("MAGNETO" .. engn .. "_START")
        else
            xpl_command("sim/fuel/fuel_pump_" .. engn .. "_prime", 1)
            fsx_event("TOGGLE_PRIMER" .. engn)
            fs2020_event("TOGGLE_PRIMER" .. engn)
        end
    end

Use the pre made hardware function?

Hi Ralph, thanks for you reply.
I've found what you say:
But the question is: must I use N. 5 input channel on my Arduino board?
By this way would reamin very few input channels for other uses.

Hi, thanks for your reply.
I don't understand what is this code and where must I put in.
Could you be clearer?

The first sample is in the case you are creating your own instrument and script through the [Create/Edit] tab in Air manager and the second one is the extract of the existing Hardware instrument you can use straight forward by adding it to any panel

Right, there's 5 positions on the Magnetos Key, so we have to use 5 input, otherwise it wouldn't work : OFF, RIGHT, LEFT, BOTH, START

Ok. I'll try. Thanks

You don’t have to use 5 inputs if you are really desperate to save I/o pins. You can save one input and not use one for off if the code is re-written. More work though for not much gain.
