DIY WHEEL - What circuit board should i use

[Tatestar1984]

Hi All,

just started a DIY Wheel, and received my wheel a few weeks backs. this is a 5mm alu plate, which has a martin Ascher Spacer and shifters . looking for something small to install on plate and inside spacer.

will have around 10 push buttons , 2 shifter inputs and 4 CTS288 rotary encoders

I can recommend a Teensy 3.2

Teensyduino: Using USB Joystick with Teensy on the Arduino IDE

www.pjrc.com

Or Arduino Nano. But it has less memory, so I don't know if a sketch for your application is small enough. Making it into a joystick is also a bit more complicated imo.

Check out the arduino pro micro. Coast less than the teensy(which is a great board btw.) and is less pain to use as an HID than the nano. Another option could be the Node MCU boards with ESP chips.

Leo Bodnar BU0836A-(NC) with matrix board. Or a board from DSD. Way more simple to use then a Arduino and all of those sketches.
Rotary Encoders are terrible with a arduino.

... Those who are willing to learn will have a good time with arduino/teensy...
If you are lazy, there are more comfortable ways of course

 

[rdauser]

If the programming part is an issue you should have a look at MMJoy.

If you don't mind soldering, I'd recommend the bodnar micro BBI. Its miniscule and very easy to set up.

i went with a leo bodnar board, as think this will be easier

Why is that?

i already have a BU0836A 12-Bit which i havent used and will add a break out board.will make a center piece to hold

I used BlueHID with just a 350mA lithium battery, that is enough to light the angel halo buttons on my rim for up to 7 hours!

Hi sorry for the hijack thread,

Is there a way to make the bodnar boards wireless?

If not I'll have to go with the BlueHID.

cheers

will this work wirelessly with the SC2 PRO

Why is that?

they don’t delay on input and poll the signal rapidly. So encoder increases or decreases are detected at double rate. So when you click once, it fires like two or three times. You can code a delay which will resolve this but if you’re using joystick library with keyboard library for a matrix, that means you can’t mix and match different types of encoders. Cheap encoders like the EC11 have a worse rapid fire issue than CTS288’s (Leo Bodnar types) so the 50ms delay ends up making CTS288’s require two or three clicks for one click to be detected. Overall it CAN be resolved but you have to use the same encoders for the whole wheel and adjust the delay to make sure it feels natural.

i was able to build my own DIY GT button plate using Arduino Pro Micro but I’m just going to order the Simucube button module and rewire it because I have two Bodnar quality encoders for my brake bias and TCS and two cheap EC11 encoders for my thumb encoders because the Bodnar encoders are huge and don’t fit in the thumb area without making the entire button housing huge. The encoders don’t fire right with the Arduino so I’m giving up on it.

Ahh. I'm still a total Arduino novice (recently dipped my toe in for the first time).
Is there a better microcontroller for encoders?

 

[ecky_123]

If you use the interrupt pins on the arduino it should run fine. Even on non-interrupt pins you can make it work by utilizing the TimerOne Library.

so my plan was to have 2 rotary encoders, 6 buttons on my wheel. wired up buttons to BU0836A but when i connected the rotary encoder, which is a cts288 didnt work at all. updated firmware, used the config software and set to 1:1 and still nothing. am i doing something stupid
