Python-Gamepad-Input

This is a small pythonsnipped for the Adafruit SuperGamePI, to map RPI-GPIO switches to the keyboard. This script maps 10 GPIO Switches and one (X,Y) analog joystick. For reading the analog input of the joystick i used the ADS1115 ADC converter ic.

ADDED PiGRRL/2 SUPPORT

FEATURES

• Designed for the SuperGamePi from Adafruit or other RPI-Based GameBoy
• Sample KEYS : up,down,left,right (digital-pad), start,select, rb,lb, X, Y, A, B
• One Joystick input
• GPIO for all RasperryPI models
• using UINPUT for sending keystrokes

HARDWARE

• 10 pcb push buttons
• jumperwires
• ADS1115(-Breakoutboard)

SETUP HARDWARE

• Connect all buttons to the GPIO (edit the right GPIO numbers)
• Buttons connected to ground, the pullup is active
• Connect the ADS1115 to the RPI I2C Bus
• Connect to the the middle pin of each pot to the first and second input of the ADS1115
• Connect the left pot pins to ground and 3.3V of the RPI

SETUP SOFTWARE

• Download the files located at /sry to your RPI
• [Install python3 sudo apt-get install python3]
• [install pip sudo apt-get install python3-pip]
• [Install the python3 uinput package pip install python-uinput]
• Download the ADS1115 libary from Adafruit (https://github.com/adafruit/Adafruit_Python_ADS1x15)
• Execute it with sudo python gpio_js_driver.py

  OPTINAL SOFTWARE SETUP

• Run /src/gpio-js_driver.py as sudo and/or add it as starup (rc.local other other)
