Teensy LC/Arduino Scripts

Ah HA i figured something out, I dont think the double presses is a problem, its only different in the regards to how I know the Fanatec "funky switch " to work.....Ive been pressing hard against the Left Right Up and Down stop which im now seeing its Activating the Push button #5. i can get clean signals by pressing on the up down left and right "gently" like you would with a D pad ......so Problem solved as far as im concerned.

Except one question, Does a rotary normally effect a X/Y slider, or does it just do more individual button presses ? I cant say ive looked into that exactly....like adjusting brake Bias in Assetto, you can do it with button clicks....does/will a game see a rotary in the way I have it set now ? Or do i need the Rotary to do button presses ?

PS re your debounce idea, I suffer from squiggly line/ohm resistance/curcuit board schematic aphobia. That might as well be written in Arabic, lol

Jk you made it look pretty simple with the resistors in line and with lables on each..... but overall with the way i have it now, it seems to be working as intended. So is there a specific reason your debounce wiring would be better ?

Ok now i have a request as i understand how Fanatec might be manipulating the script to get the Direction and the Push button to register a Single button when pressed together. Is that possible you could work out how to do that ? @tadythefish

Rotary encoder in your controller works exactly the same way as an analog slider on a jostick. So how a game sees that slider is out of my area
The rotary encoder in this teensy program doesn't do induvidual button presses. It changes the value from 0-1023 (the same way as a slider) so infact it it seen by the game as an analog value

Ok let me see if I understand what you are saying... You don't need a slider like it is setup now.. But you want the encoder to act loke this: when you turn in one direction every click of the encoder is a push of one button, but if you turn it in the other direction it acts as if you were pressing two buttons at the same time?
My debounce way is (for your needs) the same as sotware debouncing if the program is working (the two libraries not interfering with each other) so if everything is working in the test screen in windows there is no need to change the circuit

No sorry ive confused you.



The Double button press happens when you push the D pad ALL the way in 1 direction, causing you to click of the push button and what ever direction your pushing the joy stick in. I would like it so that when the teensy sees both buttons pressed, that is then make another button # press as a single button. Which is how im assuming Fanatec setup the Alps to work.

I will test tomorrow how the Current encoder script works with the games....but have a feeling it wont work as i want.

I want the rotary function to just emulate another button essentially, Roll left and you get a button press, roll left a bunch of times and it registers each click of the encoder.

Did i explain that a little better ?


PS super appreciate the help bud.

Ok didn't get the first part of the message.. But lets go one thing a time
First rotary encoder.... If i get it now every click of the encoder in lests say clockwise direction is triggering one button, and every click of the encoder in the counter clockwise direction is triggering another button
Turning left pulses one button and turning right pulses anothet button (in short) )

No problem with helping... You have to know I am learning too

Ok I hope I understanded what you wanted with encoders... I went ahead and edited your code...
You can download it in the attachment. Please try it out and tell me if this is what you wanted and then we can move on to the button problem

I cleaned up the code a little bit, but it still need some editing (only estetics)
In the file you will se where I changed parts of the code and added comments so you can better understand what is happening.
I wrote TadyTheFish where I changed parts (delete it afterwards it's not copyright hahaha )

Yes that is exactly what im thinking. I will test out your code asap and let you know. Thanks bud.

Your changed did exactly as i wanted...the rotary now makes button 11 and 12 act as button presses....So now on to the D pad + push button double press issue.

Nice to hear that we understand each other i hope it works...
As for the buttons I re read you post and I think I know what you need.
So you are trying to say that if you push the button IN you want a signal... Lets say button 1... And if you push the button forward you want a signal... Lets say button 2.. And so on for backward, left and right.. (this is how you want it to work)
But the problem is when you push the button lets say forward (to the end) you get a signal on button 2 AND button 1 (the same as if you would push it forward and press it in)?

Please check my previous post I'm in the mood for programming ))

Again I went ahead and edited the code... If my asumtion in the upper post is correct then this shoul do the trick.

PLEASE NOTE
The changes to the code are forcing you to use Button1 (looking at the windows test app) as the input for the PUSH IN
Button2, Button3, Button4, Button5 for Left, Right,Forward, Reverse ( the order is not imporant)
Button8, Button9 and Button 10 you can youse for anything you want (they don't have any effect on each other or other buttons)

Button 11 and Button 12 are (like before) used by the encoder

In this configuration (settings in the firmware):
Teensy Pin-------Windows button
0-----------------------Button 1 (PUSH IN button)
1-----------------------Button 2 (Forward or Reverse or Left or Right)
2-----------------------Button 3 (Forward or Reverse or Left or Right)
3-----------------------Button 4 (Forward or Reverse or Left or Right)
4-----------------------Button 5 (Forward or Reverse or Left or Right)
5-----------------------Button 11 (Encoder A)
6-----------------------Button 12 (Encoder B)
7-----------------------Button 8 (Whatever you want)
8-----------------------Button 9 (Whatever you want)
9-----------------------Button 10 (Whatever you want)

Please let me know how it goes

It works in 1 direction without me changing any of the pins on the teensy currently how i have it wired (from the top mount schematic view and how i have it wired its the Green Pin and the Down direction) ....Tho if i slowly press in that direction i still see the single input from the Direction pad. So while i see your code at work, Is there a way to make it ignore that initial D pad direction input ? and Also make the combo of D pad direction XX plus # 5 press = Button XX I dont want the D pad in all directions to be one single button

You have to know something... I don't have a D pad (never did) so I don't know hot you have it wired... I only know you have an encoder and a Pad that has 5 buttons inside one for push in (like enter), left, right, Forward, brackward...
So in order for me to help you ( I love to do that ) please show me some pictures and maybe how it is wired so I can better understand the situation
And did you download the modified version of the program?

OK I am looking at the pictures that you have provided on the PJRC forum and the datasheet off the encoder.. can you post a picture of the rear side of the encoder?

I see how you connected everything...
Teensy PIN--------- Wire color ---------- Enoder pin

0 --------------------- Green ----------------- A
1 --------------------- Grey ------------------ C
2 --------------------- Blue -------------------- Push
3 --------------------- Brown ----------------- D
4 --------------------- Yellow ------------------ B
5 --------------------- Orange ----------------- Encoder B
6 --------------------- Red --------------------- Encoder A
GND ---------------- Black ------------------- Ground terminal
GND ---------------- Purple ------------------ Encoder COM

Is this correct?

If this is your wiring then I have assigned the wrong inputs to the code.. here is the corrected version please try it and report back
NOTE: This shoul work as follows....
When you PUSH IN button 1 should come on (windows test screen for joystick)
When you push forward (button 2 or 3 or 4 or 5 should come on, one of them)
When you push backward (button 2 or 3 or 4 or 5 should come on, one of them)
When you push left (button 2 or 3 or 4 or 5 should come on, one of them)
When you push right (button 2 or 3 or 4 or 5 should come on, one of them)

I can't exactly tell you witch of the buttons come on since I don't know the orientation (how you have it mounted) of the encoder. But basicly this is how this code works. And we can make aditional changes

No I have it as follows Not sure if you need to tweak it again,

0 --------------------- Green ----------------- A
1 --------------------- Grey ------------------ C
2--------------------- Brown -------------------- B
3 --------------------- Yellow ----------------- D
4 --------------------- Black ------------------ Com
5 --------------------- Red ----------------- Encoder A
6 --------------------- Orange --------------------- Encoder B
GND ---------------- grey ------------------- Ground terminal
GND ---------------- Blue/Purple ------------------ Encoder COM/Push

Pin 2 or Brown is the pin that im seeing that different activity on, If i press the D pad all the way, It lets go of the D pad number press, but sill unilized the "push" button number. which isn't what i want but that might be because of the code need changing....


Again I Very much appreciate the help with this Tady, I owe ya one.

Try swapping wires Black and brown...
PIN2 is the pin that COM needs to be connected...
That pis is different from pin 0,1,3,4
The code is written that if only pin 2 is LOW (push in) you get a signal.
But if you push forward you said you get a signal forward AND push in... So i have edited the code to turn off the PUSH in signal if you press forward,reverse,left or right...
So it is absolutley mandatory that the signal that is active (when low) when pushed in is connected to pin 2 of teensy and forward,backward,left and right are connected to 0,1,3,4
So try swapping the Black and brown wires

YOU ROCK @tadythefish


That works exactly like i want and just like you said swapping the brown and black did the trick. I cant thank you enough man, I seriously owe you a favor.

You don't owe me nothing well if you are ever in Slovenia (google it ) you can buy me a beer
If in the future you have any problems with aarduinos or Teensys drop me a line.. Im happy to help.. For me I get such a great feeling that someone is happy because I was able to help

@Nick Moxley
If you want I can edit the code some more so you have all the pins used an prepared for future expansion.
One last tip... You should really put Pull Up resistors on the used pins.. So you don't get any false triggers.... I can draw you a schematic (with colored resistors). And I mean a schematic for those who are not electrically expirienced
