# Configuration
# Adjust pins for your specific board
UART_TX = board.GP0
UART_RX = board.GP1
BUTTON_PIN = board.GP15
# Setup UART
uart = busio.UART(UART_TX, UART_RX, baudrate=9600, timeout=0.1)
# Setup Button
button = digitalio.DigitalInOut(BUTTON_PIN)
button.direction = digitalio.Direction.INPUT
button.pull = digitalio.Pull.UP
# Initialize DFPlayer
df = DFPlayer(uart, debug=False, volume=10, command_delay=0.1)
print("Simple DFPlayer Example")
print("Press button to go to next song")
df.play_track(1) # Start with first track
last_button_state = True
while True:
current_button_state = button.value
if not current_button_state and last_button_state:
print("Button pressed! Next song...")
df.next()
last_button_state = current_button_state
time.sleep(0.05)
