I need to add sound to my clock. To do this I purchased the following:

Interface I2S PCM5102A DAC Decoder GY-PCM5102 I2S Player Module For Raspberry

It has the following edge connections:

GND - Connected to GND V IN - Connected to 3.3 V LCK - Connected to GPIO 15 D IN - Connected to GPIO 14 BCK - Connected to GPIO 13 SCK - Connected to GPIO 12 LINE OUT - Connected to an 8-ohm speaker

Please help me write a MicroPython program for the Raspberry Pi Pico that can help me test this device.

Response

I'll help you write a MicroPython program to test the I2S DAC module with your Pico. We'll create a simple test that generates a sine wave tone to verify the setup is working correctly.

I2S DAC Test Program

This program provides a basic test of your I2S DAC setup. Here's how it works:

  1. It configures the I2S interface with the pins you've connected:
    • GPIO 12 (SCK) for the serial clock
    • GPIO 15 (WS/LCK) for the word select
    • GPIO 14 (SD/DIN) for the serial data
  2. It creates functions to:
    • Generate sine waves at specific frequencies
    • Play individual tones
    • Run a test sequence of notes (C4, E4, G4, C5)
  3. The test sequence plays each note for 500ms.

To use this program:

  1. Save it to your Pico as main.py
  2. When you run it, you should hear a sequence of ascending notes through your speaker
  3. If you don't hear anything:
    • Check all your connections
    • Verify your speaker is properly connected to LINE OUT
    • Make sure your power connections (GND and VIN) are secure

You can modify the test_sequence() function to play different frequencies or durations. For reference, here are some common note frequencies:

1
2
3
4

`NOTE_FREQUENCIES ={'C4':262,'D4':294,'E4':330,'F4':349,'G4':392,'A4':440,'B4':494,'C5':523}`

Would you like me to modify the program to include different test patterns or features?
