What's this?

This is the seed for something better

This is a simple test script that you can use and adapt to send MAME commands to your arduino on your own cabinet you're encouraged to improve it as you wish but in no way this is something to become a production or a final product, this is made for makers only. It's my first Python script so some errors are expected.

Why

This script retrieves MAME output via ip:8000 and maps the output to a byte lamps, the output of the lamps will be processed and sent back to an arduino via serial communication. This script was used for testing purposes during a live event on: Twitch https://www.twitch.tv/kabukiflux

Installation

You need to install Python 3 on your system and pyserial as well

How to use

This script will send mame commands to arduino via serial port

1- Configure serial port below to the arduino 'com5' 'com3' in Windows '/dev/ttyUSB0' or whatever in Linux it will autodetect the first port available if you don't set it.

2- Ensure mame.ini OSD OUTPUT OPTIONS output is set to 'network'.

3- In output_map.json you can set the mame message for the right real output on arduino, the "default" part includes all the regular mappings but you can override it by using the mame name of the game.

4- Run MAME or MAME game.

5- Execute this script (if MAME is closed it will wait) ./mame_output_to_arduino.py

6- WARNING: If this doesn't work check the antivirus/firewall and set some exceptions for MAME app in network.

MAME part

A good way to test the output is to open Virtua Racing go to the test page and choose output test.

Arduino part

Just open the file mame_tcp_leds.ino in the arduino IDE, choose the pins to output on the top of the script on the array called byte pins[] you can choose there the digital outputs for your arduino. Send to the arduino. That's all. Tested on an Arduino Nano.
