Keypad matrix but with toggle switches?

[liquid134]

since you all have been really helpful with my projects, i figured i would reach out. So not too long ago i was posting about a button box that i was making for simulators. Running an arduino lenardo pro micro and i have it programmed with a modified keypad matrix script that i found online. (ill have it below).

now the issue, the game sees the toggle switches as if im turning them on n off rapidly, however, windows shows it as normal, switch is turned on, button is light up on joystick manager. I wanted to use some toggles (as well as some momentary buttons) to mix it up, make it a bit more immersive, as not ever button/switch in a car or truck is a momentary thing.

is there anyway to change this behavior on this code?

i also dont use rotary switches on this box either. is that the part thats giving me the issue? i have 13 switches and 9 buttons in a matrix.

How is your matrix wired, I assume you use have diodes if the toggles work as expected anywhere.

And what exactly happens when you switch a toggle form open to closed... and what happens when you switch back to open?

You say it acts like it is being turned on and off rapidly, it isn't clear to me when these rapid signals are showing up and in what relation to you switching the switch.

yea i found out the hard way that i needed diodes lol. so no more ghosting issues. i have it setup in a 5x5 pattern. everything registers as it should in windows game controller properties. the game however, is expecting momentary pressing, and not the toggle switch being constantly on.

so obviously i could just replace the toggles with more momentary buttons but i feel like its possible to do in code or even another app (i started seeing somewhere that a auto hot key program may be able to be used to solve this).

i need to be able to turn the physical switch to the on positon, but it needs to act as if i just pressed a button. and then when i turn off the physical switch, it needs to act as if the button was pressed once more.

Please read this thread thoroughly, I do believe it addresses the same issue.

Toggle switch act as a button (UnoJoy)

Hi, I was messing around with the UnoJoy library for some time now to get the hang of it, to eventually, construct a flight sim. But I couldn't get something to function properly, a toggle switch (spst switch). When you hook up a toggle switch to UnoJoy, it registers pressed and released only when it is toggled on and off, which is not something I'm looking for :/. I trying to figure out a way on how to trigger a button press and release as it is put in either of the on/off position (kinda hard…

At a glance @PaulRB's idea looks plausible; you'll have to figure out a way for that logic to apply to the toggles and not the push buttons, or they will start giving you action on press and release. I think. It's sleepy and I'm still a little early.

But do read that thread. Never heard from the OP, please let us hear from you as you solve this easily solved problem.

i really do appreciate your guys input!! so pauls way of doin it would of worked minute the push buttons i already have. i dug deeper into my issue, and decided to take out the resistors i put in on the columns. (i had found another forum/schematic on doin a button matrix and they added 10k resistors on the columns. i pulled those, and its working as it should. i did also find a program called SV Mapper, and that will allow me to do the on/off as i was trying to do in this topic. thanks again!
