THANK YOU! Finally! I have been asking for DCS-BIOS tutorial in forums for a year now! Such a poorly documented project. You see people with insane builds but with no directions on how you can replicate this. Please, go on with this series!

[@Joejoe-vd2do]

This is brilliant! I've made joysticks, throttles, pedals and collectives and just when I thought I've researched it all, you make an introductory video and I learn something new:) Thanks mate!

[@Joejoe-vd2do]

@repentandbelieveinJesusChrist8 Thanks? I'm Jewish

[@nigelfield2492]

I didn't know any of this and I've been messing with arduino and DCS for several years. Opened up a whole new world for customization, thanks much mate.

[@kolesplace]

There goes all your free time 😁😁

[@SVTL4799]

Thank you for this!!!! Awesome video! I didn’t realize how cheap it is… it’s worth doing just for fun, but I can already tell this is gonna lead to a much bigger project!

[@steveman1982]

A pro-micro running a script to do 100 mouse clicks per second if a toggle switch was triggered, really helped me spawn into airplanes in Battlefield 5 :) Just don't forget to toggle it again to not go through your ammo right away upon spawning.

[@hereisanaccount]

A better solution you can do in your code is to have it send that signal on a signal *rise* and a signal *fall* (this requires as far as I'm aware setting it up as an interrupt). Then when you move it to the on position, it sends the press, and when you move it to to the off position, same. Only downside is when you fire up he game you'd need to have already "reset" your switch positions. The reason I call it a better solution is it doesn't rely on a plugin that may flake out or be broken by an update. Love the content.

[@marcokorner34]

The idea to just send a short "button pressed" signal on a rising edge and another signal on a falling edge is a possible solution. But you don't need to set the pins in interrupt mode. You can also scan the pin periodically comparing the pin state with its state of the previous scan. If you see different values, you detected an edge and can send a "button pressed" signal for the corresponding button. To overcome the downside, you can re-send the corresponding signal periodically. But if the main goal of your solution is to not configure the sim to react to both button-states, there is a simpler solution: Just map each physical state of a switch to a direct-x button. The following code demonstrates this. #include Joystick_ Joystick; int pins[4] = {9, 10, 11, 12}; void setup() { for(int pin_no = 0; pin_no < 4; pin_no++) { pinMode(pins[pin_no], INPUT_PULLUP); } Joystick.begin(); } void loop() { for(int pin_no = 0; pin_no < 4; pin_no++) { int currentState = digitalRead(pins[pin_no]); Joystick.setButton(pin_no * 2 + currentState, 1); Joystick.setButton(pin_no * 2 + (currentState^1), 0); } }

[@MaxSterling01]

Thanks for this. I have always thought about building a simpit and now I have a reason to do it with quick tutorials like this one.

[@bewilderedlearningevolving]

Super cool! One of those things I've thought about countless times yet never really sat down to dig in. Thanks for sharing!

[@rogerramjet8395]

Thanks for doing this, and the one you're proposing on DCS BIOS. I've been thinking about adding a few things to my setup and this is going to make it much easier. Thanks!

[@Jager-er4vc]

I hope this will be a full series of basics videos.

[@Mersher]

I didn't know about Quaggles, very cool. I'm using mmjoy for my pro micro boards to make them appear as a generic joystick. I have made a custom circuit board I plug the pro micro into, supporting 64 buttons and 8 analog pins from a single pro micro and it's awesome. I'm almost done with a new version that bumps up to 128 buttons plus the 8 analog on a single pro micro🤘

[@DonaldMcMuffin]

You need to share that board :)

[@Mersher]

​@@DonaldMcMuffin I plan to after I get the new version proven out 👍

[@kolesplace]

Yea, where is your content video? I want to see how to do many buttons :)

[@zoranbrasnjo7488]

I did something similar. I connected 10x8 pins in the grid( including rx and tx pin,no ground) and used joystick and keypad library to program it. I have 80 buttons that work( they are all self-centering switches). Now I am figuring out a design/ layout of the switches.

[@simonegiubilato1672]

Best video ever! Please keep this kind of stuff coming! 🙏

[@GDViperWorks]

@thewarthogproject There is another way without using a mod.... pulldown Key/Button, and you will find an entry for "JOY_BTN2_off". Just bind that to the off position. This is after coding the Leonardo for joystick and bound within DCS... If it is a 3-way switch (center is off or open), bind up to one function, down to the other, and the middle to 2 "off" positions. Example the F-16 Arming is 3 position. Up - Arm, Middle - Off, Down - Simulate. If it is 2 way on/off switch, just do half of this. One position is the "button" the other is the "_off" input. It must be selected manually from the pulldown. Bind within DCS ; Arm - "JOY_BTN1" - up. Simulate - "JOY_BTN2" - down. The middle position will be bound as above using the "Key/Button" pulldown. Off - "JOY_BTN1_off, JOY_BTN2_off". Boom! Done!

[@Steenos]

You are a GOAT in the sim world! I've been following your project for years.

[@CMDR_bravoMike]

Lol I was asking about exactly this in chat yesterday, great timing 😂works great

[@fabmeloman]

Very instructive thanks for sharing your knowledge, also planning to start on f18 at some point.

[@GabrieleTamborrelli]

After this video i definitely decided to get into a project and start made my button box for DCS. Thanks for all your video. 🙏

[@aaronwhite1786]

The AH-64 controls have me wishing I knew how to 3D print my own custom assemblies and throw them together. The cyclic/collective I can make work with my Winwing/Warthog setup, but the CPG seat gets brutal with an X-Box controller and trying to fit 1,000 buttons and switches on the damn thing. Nice video, as always!

[@tommy_boy2472]

If you need help I got. I fix the apache for my job. So if you need any help I gotcha if it's within what I'm allowed

[@Erdnussflipshow]

The problem with the TGP switch is even easier to fix than you've shown, when you add a button to an action, it says the button number in the pop-up menu, just click on the number and select the button_x_off action instead of button_x, if you map both the on and off event to the toggle, it'll work as an on-off switch.

[@thewarthogproject]

This was added in a recent update (without being mentioned in any release notes?), and i didnt even know it existed lol. Ill check it out and revisit this later.

[@Erdnussflipshow]

@@thewarthogproject Seems like it, I saw a KZbin short telling people about the feature, but I'm not sure for how long it's been in the game.

[@Jackg1822]

Great video and would love to see more videos like this!

[@michaeleklof1]

Hi mate. Wonderful videoI I am now researching how to build my own cockpit and how to do it economically. I find your videos are the best out there. It turns out a lot of the libraries in Finland has a lot of the tools needed. It cost me 0.70€ to fill up the Ultimaker 3 pro plate with buttons. The laser cutters cost 1€ a go, so I am finally getting something out of the ridiculous taxes we pay over here.

[@charlyvictoria62]

por fin encuentro lo que necesita , Gracias por compartir tus conocimientos

[@Fester_]

Thumbs up before I have watched. Informative, straight to the point and easily found title. Great video, easily followed and if not on then off. Cheers.

[@theshawnmccown]

Just a heads up, I don't know exactly when DCS World added it but now you can assign a button's off position as another button press. Basically, you assign the button again but then click on "Key / Button" with your mouse and manually choose the same button but it will have "off" followed after it. Then you will see two button assignments for the same switch on the main controller screen. The switches work as they should after doing that. So, no mods or circuit setups that send a pulse to get an on/off switch to work in DCS anymore.

[@theshawnmccown]

I found a video that explains it if what I was saying was confusing. kzbin.info/www/bejne/mZDWfamQpdmhf80si=y6M5RUiJu0I1R7kv

[@eugeneaugustine5979]

Damn you for rekindling the fire to get back to doing this. 😂. Super helpful. Thanks

[@No1sonuk]

1:05 The Leonardo is the same form factor as an Uno, but has the 32u4 processor with native USB. The Pro Micro may report as a Leonardo to the Arduino IDE, but it's not the same thing. 1:54 "...six inches long..."? 6:32 Whenever I first connect such a device, DCS tries to guess which binds to use, so it's a good idea to check and clear out if necessary the axis and non-axis binds of new devices. 7:02 Looks like you put the button on the Master Caution circuit breaker bind. 8:20 WRT on/off bindings. You can program the arduino to send another pulse of the same signal, or a different button press, when you turn the switch off. You can also use this to make "virtual buttons" for on-off-on switches to give 3 separate outputs. There's also a way to increase the maximum number of buttons to 128 if you need more virtual buttons. Does Quaggles cause problems with purity checks?

[@andycrask3531]

I have no use for this currently but it was very useful thanks 👍

[@CodeRed001]

Thank you for uploading this. My f-18 simpit has almost a fully completed front panel. I have been wanting to know how to add my own switches for a while now. I use dcs bios with some premade switch boards built by tek creations but have a few buttons on my front cockpit that have 2 wires coming out of them but arent programmed or attached to anything so I need to learn how to do it myself. I know how to solder so that won't be a issue.

[@rcoplien]

I have a bunch of Honeywell switches for my F-16 pit setup on my card and they work great. Including my Ejection seat handle keyboard emulated on the card to read when I eject.

[@falcon9983]

I love listening to Aussies curse. Friggin hilarious.

[@KerboOnYT]

The Pro Micro is a great little micro. With multiplexer chips you can even have dozens of switches and buttons

[@TNT-tf9jd]

Thanks, great timing for this info.

[@hangar4851]

Though it is sometimes hard to understand you, mate, it is great to have a pro showing the basics under the lid. What I would like to know is, how the maker of DCSbios access the API methods of the aircraft.

[@sierramikebravo7332]

Bloody legend

[@malkowitch]

On an on-off switch in Arduino you can just watch button state in loop, after the state change save it to variable and send a pulse/message to a PC. The only issue is when you close the game you should reset the buttons position manually.

[@zoranbrasnjo7488]

You can also program switches connected to one pin to act like two buttons. For example when switch is on-joystick button 1 is on for 200ms and when switch changes state to off- joystick button 2 is on for 200ms. This way you can have 36 joystick buttons connected to 18 buttons(18 pins+ground) which this board have. All switches can work at the same time , if you connected 10x8 pins with no ground you can have 80 buttons but a lot of them don't work at the same time. Basically you can do whatever you want.

Freakin cool! I'm not really interested in doing this but it sure is fascinating

[@xTheUnderscorex]

keyboards definitely do send separate signals for keyup and keydown

[@glend.7652]

Wonderfully explained as always. One question lasts, if you use more than one Leonardo, is there a way to re-name the different Leonardos? I just remember my struggle with easy usb-game controllers, that where not recognized as different boards (in comparison with the Leo Bodnars where you could give them certain numbers).

[@S3NTRY]

Yes, you can change the name of the device, and its ID in the boards configuration file in Arduino

[@RafaPolit]

@The_Warthog_Project , these are very instructional. I'm wondering if you have or use Rotary Encoders and what library do use for them? Thanks.

[@speedbird8326]

Just excellent !!!

[@86abaile]

Thanks for sharing Quaggles, that's so useful. I gave up ages ago editing the game's lua files after every update. Do you know of any good tutorials on how to use and customise the joystick library?

[@S3NTRY]

How to build a button box, by wim

[@AdolphusOfBlood]

You don't need that two position switch mod, you can alter the Arduino loop to make it send the on signal for the button on a state change instead of when it's on or off.

[@braitebrina5148]

how?

[@AdolphusOfBlood]

@@braitebrina5148 The program he's referring to lets you set up when a button is on or off independent of the input it gets, so you need only set it up to stop sending the signal after a few seconds. I'll give you some example code in a separate post.

[@AdolphusOfBlood]

@@braitebrina5148 #include Joystick_ Joystick; void setup() { // Initialize Button Pins pinMode(9, INPUT_PULLUP); pinMode(10, INPUT_PULLUP); pinMode(11, INPUT_PULLUP); pinMode(12, INPUT_PULLUP); // Initialize Joystick Library Joystick.begin(); } // Constant that maps the phyical pin to the joystick Switch. const int pinToSwitchMap = 9; // Last state of the Switch. uint8_t lastSwitchState[4] = {0,0,0,0}; // Time of last change. unsigned long lastStateChange[4] = {0,0,0,0}; void loop() { // Read pin values for (int index = 0; index < 4; index++) { int currentSwitchState = !digitalRead(index + pinToSwitchMap); if (currentSwitchState != lastSwitchState[index]) { Joystick.pressButton(index); lastSwitchState[index] = currentSwitchState; lastStateChange[index] = millis(); } if (millis() > (lastStateChange[index] + 100)) { Joystick.releaseButton(index); lastStateChange[index] = millis() + 1000; } } delay(50); }

[@aussieshooter5358]

LMAO the ending!!

[@SeanAnwalt]

Thank you! This is awesome.

[@ComdrStew]

7:15 Problem is ED too lazy to program a Release to all the switches. Make it like MSFS 2020 where you can select activate or release for the same button. I use RS Mapper to get around it, but Quaggles looks a lot easier, since you don't have to use a separate program. Is there a profile for Quaggles you can save?

[@thewarthogproject]

Lots have people have since told me DCS can do this natively since a recent update, although i havent tried it out yet because i had no idea it was possible. Ill revist it later on!

[@OfficialRedDirtNurse]

The typical workaround (I use) with switches in DCS is to assign TGP ON = JOY_BTN2 (on), and TGP OFF = JOY_BTN2 (on release). This is native to DCS and seems to work fine without the need for any third party apps.

[@patty_cakes5596]

i use this too but what i dont like is if your switches are out of sync at the start they stay out of sync. this is extra annoying if you are playing in something like a huey where the ai co pilot will sometimes flip switches randomly.

[@user2C47]

​@@patty_cakes5596 That's why I made all my switches momentary, so there will never be a mismatch between the hardware and the game.

[@Bank_left]

Great video lots of helpful information? Could you please do another video on modifying Lua specifically for the Hud and the modifications you made with it and the Is a o a indicator

[@primoduck]

I'm using toggles in DCS with a simple panel I made. You can get around the issue of having to throw the switch twice by using a simple if statement. should look something like this for the Joystick library. if (digitalRead(button1) == LOW) { Joystick.setButton(0, 1); } else { Joystick.setButton(0, 0); }

[@Dcscockpit]

Thanks for this, gives me the push I need to get my cockpit going it’s easier than I thought. Quick question, how would we do a 3 position switch? If we solder both poles to inputs that’s well and good but DCS only allows one switch input for that 3 position switch and I’m assuming that would show up as two independent switches.

[@einweiesblattpapier2676]

Thanks a lot man, youre a life saver. Just one question: can you actually connect any switch to this card (specifically rotary switches)?

[@OzDeaDMeaT]

A quick way to open up the game controller interface is to type 'joy' into the start menu.

[@MMORPG87]

i had this issue with a toggle on my virpl throttle then found out i can change how it works in the software itself to work just like u showed

[@mattbrigden3671]

I am attempting to build a couple of basic button boxes and I wasnt aware such a mod existed, however, after downloading all input commnds from munkwolf I have discovered that all the files are blank!!

[@dyncoder]

You should be able to just change the code so that it sends a signal whenever the state of the switch changes. You just save the last state in a boolean variable and send the signal when it isn't the same.

[@remotex8396]

i have finally made myself a ufc thanks this series. Well almost an UFC it still needs some Displays, so are you going to make a tutorial on it cause I can figure it out by myself:(

[@swazi98kl]

Hi. Will be making your 180 screen. What was the radius you used. Enjoying the content. Thanks

[@RealDaveWinter]

Why would you modify DCS? The Arduino is programmable, with C code. Just have the Arduino monitor the state of the toggle in a loop and send the appropriate signal to DCS? That would take all of about 5 minutes to code the script and you're not screwing around with DCS. It seems like you've taken the backwards approach.

[@shooterdefronvrps2]

dcs dont have toggles commands like some fps allow aim,chrought, sprint and other functions 2b toggle so you press it once start,press twice it release instead of having to hold that button on a state

[@Spikejwh1]

Are you sure you cannot solve the toggle switch problem with software in the Arduino. You can tell it to give a single pulse every time it changes level from 0 0.

[@ItsJustSteve]

7:18 Wouldn't the "Switch OFF" option in the DCS controller editor work for this?

[@deniskalugin7984]

Noob question. Toggle switch when it is ON is like to push and hold button on a keyboard, right? AFAIK, Windows and games (WarThunder to be specific) do not support the state when 3 buttons are held simultaneously. It means that if you hold 3 buttons, the system will not recognize if you push the 4th button. So, is there a problem, when you have 3 toggles swithes ON? I hope I explained my question.

[@zc240x7]

The end LOL

[@TallWestEddy]

Great video, how do you add more pin modes to that? It’s only allowing 4 pins to be connected..

[@Nick-Taylor]

I think I am better to pay the extra 50c and get the type C connector version. its a fraction longer, but that doesn't bother me. Thanks!

[@Dcscockpit]

Disregard, I see DCS actually does have individual binds for up and down and middle on switches as well as a 3 position bind. Thanks though

[@kolesplace]

Great content. Now for the complicated question. If I have 75 switches to wire up, what is the preferred solution? Multiple Arduino boards plugged into a USB hub?

[@DriftNick]

You could use a button matrix though you might run into issues with toggle switches using that, you can also have multiple Arduino's using one usb, one is the master that you plug into your computer and the others (slaves) are wired into the the master.

[@primoduck]

I's suggest looking into a large button matrix if you are only using pushbuttons (a matrix only really works well with momentary push button switches), or you could cascade a bunch of shift registers like the 74HC165's possibly.

[@andrew1977au]

Hahahahaha alesst 6" you say 😂😅 nice one

[@Dcscockpit]

I’d like to note that your wrong with adding more pins, adding those lines with the additional pins is NOT the only thing you need to do to use all the inputs of the board, there are actually 3/4 more lines that need to be edited in the code, I’m really not sure why the example doesn’t do all the pins, if you don’t use them all then they just don’t get used lol

[@TallWestEddy]

Do you know how to add more? I’m a noob, but have this set up could do with adding more to maximise the board…
