I2S Schnittstelle PCM5102 DAC Decoder GY-PCM5102 I2S Player Modul für Raspberry Pi
// Example pin mapping (change to your wiring): // BCLK -> GPIO26 // LRCLK -> GPIO25 // DOUT -> GPIO22 // // This sketch generates a 440 Hz sine wave (stereo, 16-bit, 44.1kHz) // and outputs continuously via I2S to the DAC (PCM5102).
