Introduction

This is a embedded-system project based on open source codes for games, which implements gamepad to control keyboard using STM32. We intended to design stm32 as a video game controller which can easily adapt on different keyboard-controlled video games with sensitive controlling, low energy consideration and some user friendly designs. Specifically, we will demonstrate our project on Mario kart game and pong.

Motivation

Mario Kart as well as other keyboard games are interesting for most age groups, but is it possible to take a step further? In this project, we use STM32 as game controller, and we expect to have a better gaming experience than using keyboard. The first game we play is an open source game project, Süper Mario Kart, and the second game we demonstrate is pong.

Dowload Steps

1. Download repository

2. Prerequisites:

   controller
   a. MBED OS 6.x (Mbed Studio)
   b. Python 3.7 + keyboard package (pip install)
   c. Stm32L4 (B-L475E-IOT01A)
   d. Wires
   e. 3 buttons
   mario kart game
   f. MinGW32 posix 8.1.0 or GCC 7.5.0 (C++ 11 compiler)
   g. SFML 2.5.1 (graphics generation and audio playback)
   h. OpenAL (cross-platform API for 3D audio)
   please check out the link for more information about compiling the game on your own

3. Settings

   a. Wifi

   • MBED:

     i. Go to ./mbed_final/mbed_app.json and change wifi-ssid and wifi password to your own wifi:

     "wifi-ssid": {
         "help": "WiFi SSID",
         "value": "\"thessid\""
     },
     "wifi-password": {
         "help": "WiFi Password",
         "value": "\"thepassword\""

     ii. Go to cmd to find your server’s IP address:

     In cmd, type in

     ipconfig /all

     then you will see in one row that says IPv4 Address, and your server's IP address comes right after.

     iii. Change the IP address in ./mbed_final/wifi.cpp to your server’s IP address

   • Python:

     iv. Go to ./python/server.py and change the host to your server’s IP address and make sure the wifi is the same as stm32's, i.e. the one mentioned in iii.

   b. Stm32

   • Equip 3 buttons on stm32

     i. top button should connect to D2
     ii. left button should connect to D1
     iii. right button should connect to D0
     please check out the manual (p.10) for more information about the ports on stm32

4. Start playing

   a. launch server.py
   b. connect stm32
   c. start your game
   d. enjoy
