Having trouble running player-sd-audiokit.ino on ESP32 AudioKit V2.2

[jimjing]

I got my board at amazon.

I am able to run the streams-url_mp3-audiokit example nicely. But when I try to run the player-sd-audiokit.ino example, I am getting in the console repeated [E] AudioSourceSD.h : 48 - SD.begin cs=13 failed errors. Did the pin for chip select changed for this version of the board? Is there any easy way to find out?

I also confirmed the dip switches on the board are OFF, ON, ON, OFF, OFF

Thanks. This is a really well documented project.

You can find the relevant information in my old AudioKit project:

Thanks for the reply. I have triple checked my dip switches and used continuity test to make sure the pins are connected correctly as well. What is IO13 conflicting with in this case? Do I just have a faulty board?

Assuming you use Es8388v1, it would be the second key. I am getting this message as well and as long as you don't press any key the SD should still work, even if dip switch 1 is on, but to avoid any issues it is supposed to be switched of. Don't forget to reboot after changing the dip settings.

The SD pins are the same across all boards....

class PinsAudioKitEs8388v1Class : public DriverPins {
 public:
  PinsAudioKitEs8388v1Class() {
    // sd pins
    addSPI(ESP32PinsSD);
    // add i2c codec pins: scl, sda, port, frequency
    addI2C(PinFunction::CODEC, 32, 33);
    // add i2s pins: mclk, bck, ws,data_out, data_in ,(port)
    addI2S(PinFunction::CODEC, 0, 27, 25, 26, 35);

    // add other pins
    addPin(PinFunction::KEY, 36, PinLogic::InputActiveLow, 1);
    addPin(PinFunction::KEY, 13, PinLogic::InputActiveLow, 2);
    addPin(PinFunction::KEY, 19, PinLogic::InputActiveLow, 3);
    addPin(PinFunction::KEY, 23, PinLogic::InputActiveLow, 4);
    addPin(PinFunction::KEY, 18, PinLogic::InputActiveLow, 5);
    addPin(PinFunction::KEY, 5, PinLogic::InputActiveLow, 6);
    addPin(PinFunction::AUXIN_DETECT, 12, PinLogic::InputActiveLow);
    addPin(PinFunction::HEADPHONE_DETECT, 39, PinLogic::InputActiveLow);
    addPin(PinFunction::PA, 21, PinLogic::Output);
    addPin(PinFunction::LED, 22, PinLogic::Output);
  }
};

Try to comment out all action commands in the sketch and double check if that helps...

[jimjing]

Comment out all action commands unfortunately didn't help. Just to confirm, when you say

I am getting this message as well

Are you saying you are getting repeated [E] AudioSourceSD.h : 48 - SD.begin cs=13 failed as well when you run the player_sd_audiokit example? Are you able to play any mp3 from the sd card in that case?

I also saw at the beginning of the log Warning: Pin '13' not set up because of conflict which could explain the SD.begin cs=13 failed error.

[pschatzmann]

I confirm that I am getting this message as well: it is there to inform you that the Pin definition for the button is ignored in favor of the SD setup.

I suggest that you try to run the SD example that comes with ESP32 Arduino by adding the following

// These pins are defined in the HAL
#define PIN_AUDIO_KIT_SD_CARD_CS 13  
#define PIN_AUDIO_KIT_SD_CARD_MISO 2 
#define PIN_AUDIO_KIT_SD_CARD_MOSI 15
#define PIN_AUDIO_KIT_SD_CARD_CLK  14

void setup() {
    SPI.begin(PIN_AUDIO_KIT_SD_CARD_CLK, PIN_AUDIO_KIT_SD_CARD_MISO, PIN_AUDIO_KIT_SD_CARD_MOSI, PIN_AUDIO_KIT_SD_CARD_CS);

Don't forget to change SD.begin() to SD.begin(PIN_AUDIO_KIT_SD_CARD_CS) in the sketch

ps. did you try to change the pin switch and then set them back again to off, on, on, off, off ?
