Projet Stick Arcade 2 Players (For Mame)
  • Stick Arcade USB for 2 players
  • 2 sticks + 8 buttons for each player (30+ buttons total)
  • USBHID / Arduino / Woodworking



Overview

This project is about making a working, robust but "cheap" arcade stick. The stick is to be plugged in USB to a computer in order to play Mame arcade emulator or other games.

This project is made of 3 parts:

  • Input multiplexing modules : making it possible for a simple arduino or Atmega chip to hold 30+ almost simultaneous inputs from players
  • USB HID Module : The device will create 2 gamepad HID and a keyboard HID on host computer
  • Stick body : mainly wood/metalworking in order to get a sturdy case (the arcade stick has to be strong and durable)

Input Multiplexing

Since I am using an Arduino diecimila, there is not enough I/o pins to manage 30 input buttons. So multiplexing is needed to make it all fit in.

The multiplexing part is designed to be modular.

  • Each board is based on a 74hc165N PISO shift register.
  • Pull up resistors are made with a 8* 9Kohm resistor array but can be replaced by equivalent (or whatever) simple resistors
  • These chips can be daisy chained giving a good opportunity to think about scalability.
  • A module handles 8 inputs and uses 4 wires of the arduino (+ power and ground).
