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)
