Example Code for Raspberry Pi

Below is an example Python script that demonstrates how to read inputs from the Arcade Bonnet using the GPIO library. This script assumes you have already installed the necessary libraries and configured your Raspberry Pi for GPIO access.

import RPi.GPIO as GPIO
import time

Set up GPIO using BCM numbering

GPIO.setmode(GPIO.BCM)

Define button and joystick pins (replace with your actual pin numbers)

button_pins = [3, 4, 5, 6, 7, 8, 9, 10, 11, 12] joystick_pins = [13, 14, 15, 16]

Set up pins as inputs with pull-up resistors

for pin in button_pins + joystick_pins: GPIO.setup(pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

try: while True: # Read the state of each input for pin in button_pins: if GPIO.input(pin) == False: print(f"Button {pin} pressed") time.sleep(0.2) # Debounce delay

    for pin in joystick_pins:
        if GPIO.input(pin) == False:
            print(f"Joystick direction {pin} activated")
            time.sleep(0.2)  # Debounce delay

except KeyboardInterrupt: # Clean up GPIO on CTRL+C exit GPIO.cleanup()

Clean up GPIO on normal exit

GPIO.cleanup()


Remember to replace the `button_pins` and `joystick_pins` lists with the actual GPIO pin numbers you are using for your buttons and joystick. This script will print a message to the console whenever a button is pressed or a joystick direction is activated.
