import audiobusio

audio = audiobusio.I2SOut(board.A0, board.A1, board.A2)

tone_volume = 0.1 # Increase this to increase the volume of the tone.

frequency = 440 # Set this to the Hz of the tone you want to generate.

length = 8000 // frequency

sine_wave = array.array("h", [0] * length)

for i in range(length):

sine_wave[i] = int((math.sin(math.pi * 2 * i / length)) * tone_volume * (2 ** 15

- 1))

sine_wave_sample = audiocore.RawSample(sine_wave)

while True:

audio.play(sine_wave_sample, loop=True)

time.sleep(1)

audio.stop()

time.sleep(1)

Now you'll hear one second of a 440Hz tone, and one second of silence.

You can try changing the 440 Hz of the tone to produce a tone of a different pitch.

Try changing the number of seconds in time.sleep() to produce longer or shorter

tones.

I2S WAV File Playback

The second example plays a WAV file. You open the file in a readable format. Then,

you play the file and, once finished, print Done playing! to the serial console. You

can use any supported wave file().

Update your code.py to the following.
