Looking to add physical buttons to select what the Knobster will control.

#1 Post by robertwaite » Fri Sep 25, 2020 11:50 pm

Hello,
I want to get the behavior depicted in the below screencast to use the knobster instead of a hard-wired dial knob encoder.
https://www.youtube.com/watch?v=mWfKkJd ... tion=share

As in the screencast, my intention is to use this for when MSFS2020 eventually gets VR support.

I assume at this point its not possible to wire in an Arduino button with a function to explicitly set a control as if we selected it with a touch screen.
I want to rule out that assumption before i start playing with an idea i have. Can anyone confirm that assumption?

Ive got some research to do to get up to speed on custom hardware controls before i can do this. My thought is to have a single dual dial control on the interface that is selectable via any normal Air Manager panel. this would be the only control selected while under VR and the Knobster would then always be manipulating that control. I should in theory I should be able to set Inter-instrument communication variables via the button presses on the Arduino to set what I want to control. The code on the primary dial dial control on the panel would send events based on what the active inter instrument variable are.

The only thing that is not clear to me yet is how to configure a dial control. the API documents and the online tutorial only shows a single dial. if you know of any reference that would point me in the right direction on how to set up dial with button control let me know. I only got my knobster yesterday and this will be my first air manager control i will be creating. So I understand i have a learning curve ahead of me.


Again the main thing I'm after is how to create a dial dial control that can be selected for control by a knobster in a conventional air manager panel. Once i figure that out everything else should fall into place. In the meantime ill be hitting the API documents and examples for clues.

thanks I'll be happy to share the end result here once i figure it out.
Robert

I've found a Generic - Knobster avionics controller I think I'm going to be able to use as a starting template.
This should be a good start as opposed to starting with a scratch control. in theory, if i can set inter interment variables via other instraments i should be able to switch what i am controlling and use this as a single point to select in an Air Manager panel.

Hi robertwaite and welcome to the forum,
I assume at this point its not possible to wire in an Arduino button with a function to explicitly set a control as if we selected it with a touch screen.
Your assumption is correct.

Your idea is totally doable and if i'm not mistaken has been done before. To get a dual dial you simply co-locate 2 dials at the same location. You just need to make the outer one larger than the inner one. Check the GNS530/430 overlay code for an example.

interesting ;)
It would be quite good fun to experiment - for vr - with either an air mouse or a normal mouse (you can of course use more than one mouse at the same with windoze.) - a sort of dedicated 'frankenmouse' where a knobster type arrangement is grafted on (or even a single small encoder with the push button selecting inner or outer) . then the mouse selects the control, and the grafted on encoder(s) do the adjusting - the whole unit moves as one. This may well be interesting with an air-mouse as well (with a suitable encoder arrangement grafted or clipped on) so you only have to move and select the control with the mouse and then use the encoder (knobster) as 'normal' - basically a mouse or pointer mouse with a control attached. - possibly even a track ball with built in /on knobster. It may be even more intuitive in VR ? ..
There are a few REALLY small dual concentric encoders from aliX at the moment... you would probably need 3d printed knobs... but the ability to have the mouse movement, button click select
and the encoders(s) all in one unit would be fun. These units are pretty tiny.
As said, using more than one mouse is no issue, so you could have a 'normal' mouse and a 'franken-mouse' ..... ;) would definitely be fun to experiment with.

general idea of size of the mini dual concentric encoders. REALLY neat units !. - also have push button as well. ;)

You may also be able to use the original idea with a static button reference via sim message port (arduino custom interface) and do the main work on an arduino.. that would probably accomplish what you want,
Worth exploring ...

Thanks for your responces,

If there are others that have done similar stuff i would like to see to so that i can glean some ideas.

Ive made a lot progreess and have come up with an even better strategy that uses the Knowbster itself to switch between modes instead of physical buttons.
Being that with the button press having a pressed and released state you can essentially get 4 additional events out a dual encoder being you can press turn then release.
So over been using that to switch between mode and then getting a sound event on the release to remind me what mode i am in.
within the structure of the modes you define the mode transition so that you have structured navigation while holding the button and turning the encoders.


I still got bugs to iron out but this is My code so far:

Code: Select all

msfsEventFlag = "MSFS_"
debugMode = true
emptyString = ""

--Debugging tip: set this to true and you can default in as pressed and test without a knobster
--local pressed = true --Debugging mode
pressed = false
local changedDirectionSincePressed = false 

local resetMode = "KnobsterMode_Heading1"
local knob_rot = 6

local pressed_outter_knob_ccw_function = resetMode
local pressed_outter_knob_cw_function  = "KnobsterMode_COM1"
local pressed_inner_knob_ccw_function  = resetMode
local pressed_inner_knob_cw_function   = "KnobsterMode_COM1"
local button_function          = msfsEventFlag .. "GPS_MENU_BUTTON"

soundAltitude_Mode         = sound_add("Altitude_Mode.wav")

soundHeading2              = sound_add("Heading2.wav")

    if ModeName == "Nav2_Mode" then sound_play(soundNav2_Mode) end
    if ModeName == "VS_FLC_Mode" then sound_play(soundVS_FLC_Mode) end    
    if ModeName == "AutoPilot1" then sound_play(soundAutoPilot1) end

Re: Looking to add physical buttons to select what the Knobster will control.

Hi Robert, I have never had need for, or used the knobster, but it seems you are making great inroads to a super solution for a long standing issue with VR.
I also have tried VR, but never wanted it or preferred it over my main physical / multi monitor cockpit project. But of course, things are moving on rapidly.
What headset are you using ? and also - what are your ideas for operating switches etc ? I can see how a simple approach to stepping through rotary solutions is excellent (and of course you can have a simple readout as to which function is selected in your approach to the problem (excellent :) !) .. but again, what about plain old switches ? what ideas do you have ?
Great work, keep it up. :D

Also, it is great to use the </> solution (check the icons above the post window) to embed your code in your post - it makes it much easier to read. If any issues with that, search the forums. Even 'seasoned' users have proven to have issues with that. ;)
Nice work.

Hi @robertwaite

Please edit your post and place the code within the code box. Click on the </> icon. It will make your post so much cleaner and easier to read and comment on.

Thank you

Awesome @robertwaite

Thank you, The main reason is so that we can select all and past into a test instrument. That way we can test and see exactly what you are doing.
I have not had the time to go through what you are doing. But your concept looks interesting.
