DIY Arduino Buttonbox

well.. this project, its exaclty the same i use on 2012, for physical changes on my f1 add for t500rs. works perfect, but wires between platform and wheel still a great problem... some idea how to wirelless project??

some pics how to

Probably the easest way to go wireless - to program SPI interface and connect Arduino to something like
Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE)

Or if don't have to stick to Arduino at all you can use only one board like
Adafruit Feather nRF52 Bluefruit LE - nRF52832

You try? I mean... probably wirelless have a high ms input lag? Or its acceptable?

Easiest Bluetooth setup to do is the BlueHID. its relatively cheap, its dead nuts easy to setup, the only real downside is the size of the board.

Didn't try yet..
Input lag is probably higher than wired, but can't say how much

I bought a couple of arduino micro pro's and used the last joystick sketch. Pretty with it and the small size is perfect for building steering wheels.

Everything works perfect except my CTS rotary encoders. First i had to turn them four steps to register one click, then i switched to " half step" which improved, but it still takes two steps for the rotary to register 1 click.
So i probably need a "quarter step" setting for my CTS encoders, but i have really no idea how to edit this in the sketch.

I hope that somebody can help me out here.

I have the same problem. Can someone help me?

Try Chained for encoders, There is a small bug in the build somewhere on encoders....going to chained fixed it.

What do you mean with chained?¿? I'm a newby.
Thx

Options for Encoders are Single or Chained, Set them up in chained the same way you would single. That should solve it for you I would hope.

Ok that's perfect but... what do you mean with chained¿?¿¿
Something like this??

Hi, I'm trying to get started with this and have limited Arduino experience.
My current issue is the Joystick library, I've placed it in the library folder but that's as far as I get as it doesn't show in the menu or Library Manager.

There is an error message

Invalid library found in N:\Program Files (x86)\Arduino\libraries\ArduinoJoystickLibrary-master: N:\Program Files (x86)\Arduino\libraries\ArduinoJoystickLibrary-master

I also tried using Add zip Library but it still won't show and same error.

Any Ideas on this one as I'm stumped.

Never mind I sorted the problem, wrong library.

I messed up the matrix, did not pay attantion to the instruktions "sry"
Before i cut everything up, is there an way to define button presses by.
Example: Pin10+pin14=Button12, Pin10+pin21=Button14, in the code?
Because then i can make it without cutting.
I got it working with 5 rotaries

Never mind, it seams to be to complicated for me, after looking in the keypad library.
So i resoldered 4 of the buttons and now all of them work.

Can 6 encoder be used?

Hi @Henrik ,

I was wondering what sketch you are using for the 5 rotaries. This is because I'm busy with an F1 Steering also with 5 encoders and 25 buttons.
Wheel like attached and using the matrix (also attached)


I also attached my code, hopefully you can take look at it?

Many thanks for now,

Bakhol

Anyone can explain what is chained for the encoders? I make work the rotarys perfectly but the cst288 don't work fine. I can get only one pulsation every four.

How did you connect your Arduino Pro Micro to Arduino Leonardo. Can you show with diagrammatize thank you so much sorry for my english.
