I2S with CrowPanel 4.3'' HMI

oliver

Can somebody please provide the correct PinOut for playing audio files via I2S speaker port ?
I can find any SDOUT port in the documentation .

Thanks in advance

regards
oliver

By the way even the sample code in the Tutorial "Play music" throws the error "Invalid Pin"

oliver

Having adjusted to the correct PINs i encounter WAV files are not playable via I2S neither STERO nor MONO .
It crashes with
Guru Meditation Error: Core 1 panic'ed (IntegerDivideByZero). Exception was unhandled.

Hi Oliver,
Regarding your issue, please refer to the image below and try the following code(please put the code in an .ino file).

#include <Wire.h>
    #include <SPI.h>
    #include <SD.h>
    #include <FS.h>
    #include "Audio.h"
    Audio audio;

    #define I2S_DOUT      20
    #define I2S_BCLK      35
    #define I2S_LRC       19

    //4.3
    #define SD_MOSI 11
    #define SD_MISO 13
    #define SD_SCK 12
    #define SD_CS 10

    void setup() {
      // put your setup code here, to run once:
      Serial.begin( 9600 ); /*初始化串口*/
      pinMode(SD_CS, OUTPUT);      digitalWrite(SD_CS, HIGH);
      SPI.begin(SD_SCK, SD_MISO, SD_MOSI);
      SPI.setFrequency(1000000);
      SD.begin(SD_CS);
      audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT);
      audio.setVolume(21); // 0...21
      audio.connecttoFS(SD, "/123.mp3");
    }

    void loop() {
      // put your main code here, to run repeatedly:
      audio.loop();
      //audio.stopSong();//关闭
    }
