Yellow ESP32 based 2.8" screen - no sound (I2S)

Other Hardware Displays
1

Hello all
I have a cheapy Chinese ESP32 based touchscreen.

Its based on a Ili9341 display driver.

I am working through the examples for various features and (after a lot of faffing), got most things working.

But, the sound doesn't and I can't see why,
It outputs on pin 26 but all I get (using any examples) is a clicking noise at boot and then nothing else.

I am suspecting a dud board, as I don't think there is much else to try.

One of the examples is the following:

#include <Arduino.h>
#include <WiFi.h>
#include "AudioFileSourceSD.h"
#include "AudioFileSourceID3.h"
#include "AudioGeneratorMP3.h"
#include "AudioOutputI2S.h"

AudioFileSourceSD *file;
AudioGeneratorMP3 *mp3;
AudioFileSourceSD *source;
AudioOutputI2S *out;
AudioFileSourceID3 *id3;
SPIClass SDSPI(VSPI);

void setup() {
  Serial.begin(115200);
  Serial.println();
  WiFi.mode(WIFI_OFF);
  delay(500);

  pinMode(5, OUTPUT);
  digitalWrite(5, HIGH);
  SDSPI.begin(18, 19, 23); // SDSPI.begin(SCLK, MISO, MOSI);
  SDSPI.setFrequency(1000000);
  SD.begin(5, SDSPI);
}

void playMP3(char *filename) {
  file = new AudioFileSourceSD(filename);
  id3 = new AudioFileSourceID3(file);
  out = new AudioOutputI2S(0, 2, 8, -1); // Output to builtInDAC
  out->SetOutputModeMono(true);
  out->SetGain(1.0);
  mp3 = new AudioGeneratorMP3();
  mp3->begin(id3, out);
  while (mp3->isRunning()) {
    if (!mp3->loop()) mp3->stop();
  }
}


void loop() {
  playMP3("/Olsen-Banden.mp3");
  delay(100);
}

The demo file is set up, but I just get a click. It does say it's found the file.

Ideas? I don't actually know what pins are used to create the I2S output.

You'll need to use a DAC that takes an I2S output. If you want to run this code directly on an ESP32, you could probably output to the internal DAC, but the sound quality is crap.

I used a HiLetGo PCM5102 I2S DAC (next to the ESP32 board) on this project and the audio is very good.

Ignore the solder spatter near the regulator...

These boards can directly drive a small (very small) speaker. There is an IC onboard that takes care of that and many moons back I had one of these screens and the audio demo's worked with a speaker attached.

That is why I am suspecting a dud board

4 
out = new AudioOutputI2S(0, 2, 8, -1); // Output to builtInDAC

That's the line I'm not so sure about. There is indeed a built-in 8 bit DAC on the ESP32 but I don't recall its interface being I2S. When you put the audio output into I2S mode, I thought that it only outputs I2S signals, expecting an external DAC.

Or at least that's what I remember from the project in the photo (a custom car stereo).

I have a couple of those CYD boards. Are you saying that they have an external speaker driver? The documentation is pretty crappy so I wouldn't be surprised to find out that I never noticed that.

Did some digging and I must have forgotten this

I2S output can also be routed directly to the Digital/Analog Converter output channels (GPIO 25 & GPIO 26) to produce analog output directly, rather than via an external I2S codec.

I found a little info about the onboard amp, so that explains how the speaker was working.
Is there an onboard connector for the speaker? I want to try one of the demos.

This is the board

There are examples around, but it has taken some serious faffing to get it to work.
BUT... handy little thing for £5 if I can get it all working.

I know the audio examples work. A couple of years back I tinkered with one of these and the audio examples definitely worked.
That was with a small speaker plugged directly in.

The examples don't have any 'setup' commands in them, so that is what makes me think the board might be dud.

There is a known issue with the sound quality, and this video shows you how to correct it...

A few of the audio examples I have here are as follows: I have marked them in my folder as working, so I must have had something right

So I got my 5" CYD to play audio finally, but only from an embedded file. Trying to use SPIFFS it claims "file not found" although the SPIFFS tester says that the file is there.

Annoying...

[edit]
Gotta just love buggy Arduino demos!
Now that I have it working, my best suggestion is to be sure that the I2S pins for the board you have match what's in the program. My board had two schematics and it wasn't until a few hours later that I noticed the pin numbers for the amp were different on each one.

And then I had issues with the demo code...

8

I can't actually work out what pins I need to use.
As it's a demo for an ESP32 (they all are), I assumed they would be correct.

But... I can't see how to define them anyway.
The circuit diagram for this touchscreen only shows pin 26 connected to the output.

I am assuming the other pins not shown are the default ones?

9

Yeah, I made the same assumption. Four hours later...
If there's one thing I've learned about all my ESP32 boards is to take any documentation with a grain of salt.

Anyway, it looks like another difference between your CYD and mine is that yours is using the internal DAC while mine has an external I2S DAC. So that means it should output to pin 26 by default.

As best I can tell,

out = new AudioOutputI2S(0, 2, 8, -1); // Output to builtInDAC

Corresponds to using the internal PDM DAC (not the 8-bit one) on pin 26, but I see a comment from 2018 saying that the PDM DAC isn't working on ESP32, so I don't know how helpful that is.

Maybe try replacing that line with

out = new AudioOutputI2S(0, INTERNAL_DAC, 8, APLL_DISABLE);

And see if that helps?

10

Gotta love the Chinese :roll_eyes:
But... pay peanuts, expect hours (if not days) of faffing around and swearing

I'll try those commands and report back

11

OK, Still dead, so fairly sure its a dud board.

But...

out = new AudioOutputI2S(0, 1, 8, -1); // Output to builtInDAC

How the heck are we supposed to know what those arguments are?
I can find no reference for them anywhere. Why don't they put them in the Keywords file?

I just don't understand these folk that write libraries and then don't document how to use them

12

Ran the hot air gun over the PCB and reflowed the ESP32 and the sound components....

Working

13

The downside to the explosion of Arduino-compatible boards and libraries is that the quality of documentation has taken a hit, especially for the hardware. I agree with you. After you mentioned that the CYD had a speaker, it took hours of research for me to even figure out how to use it.

14

Well after many many many evenings, I have abandoned these screens

Getting literally anything to work with them is an uphill battle.
Been all evening trying to get a touch library to work correctly.

Coupled with the insane 20 minute initial upload time to the ESP32, they are just not worth the effort.

The main problem (documented elsewhere as well), is due to some very poor design, you can't use the SD card and the touch screen at the same time without either lifting some pins off the touchscreen controller and rewiring them, or cutting some traces.

Going to go back to the good old Teensy 4.1 and a relevant touchscreen or a Nextion screen if I am feeling flush.

Thanks AliExpress. It's been rubbish :grimacing:

I found a solution to play MP3s with CYD, so I asked for it to be reopened.

I use the library created by the author of the video introduced in post #6. However, since the original was for PlatformIO, I made it into a library for Arduino and modified it so that it can be compiled with ESP32 board package 2.0.17 to 3.1.3 (however, this is only a modification of CYD_Audio).

I forked the original GitHub repository and set the default branch to arduino.

I wrote a simple README.md, but I will introduce it here as well.

Cheap Yellow Display MP3 Player

Requirements

  • Arduino IDE: Tested with 2.3.5
  • Board package: ESP32 by Espressif 2.0.17 - 3.1.3
  • Board type: "ESP32 Dev Module" or "ESP32-2432S028R CYD"

Installing Library

  1. Fork or download the repository ESP32_TFT_PIO to your PC.
  2. Copy CYD_Audio folder in Examples/CYD28_BaseProject/lib to your Arduino library folder (e.g. Arduino/libraries).

  SPI.setFrequency(10000000); // 1MHz --> 10MHz or more?
  if (!SD.begin(SD_CS)) {
    Serial.println("Cannot begin SD.");
    while (1);
  }

  audioInit();
  delay(100); // Wait until the task on Core 1 is ready to receive a command
  audioConnecttoSD("/test.mp3");
}

void loop() {
}

// optional
void audio_info(const char *info) {
  Serial.print("info        ");
  Serial.println(info);
}
void audio_id3data(const char *info) {  //id3 metadata
  Serial.print("id3data     ");
  Serial.println(info);
}
void audio_eof_mp3(const char *info) {  //end of file
  Serial.print("eof_mp3     ");
  Serial.println(info);
}
void audio_showstation(const char *info) {

void audio_showstreamtitle(const char *info) {
  Serial.print("streamtitle ");
  Serial.println(info);
}
void audio_bitrate(const char *info) {
  Serial.print("bitrate     ");
  Serial.println(info);

void audio_icyurl(const char *info) {  //homepage
  Serial.print("icyurl      ");
  Serial.println(info);
}
void audio_lasthost(const char *info) {  //stream URL played
  Serial.print("lasthost    ");
  Serial.println(info);
}
  1. Open CYD_MP3Player_Basic.ino and change the filename to your preferred .mp3 file.
 audioConnecttoSD("/test.mp3");
  1. Save the .mp3 file to the root of the microSD card and insert it into the slot on the CYD.
  2. Select your board type and change the configuration settings from the IDE's Tools menu as follows:
  • Partition Scheme: "Huge APP (3MB No OTA/1MB SPIFFS)"
  • Upload Speed: "460800"
  1. Compile & upload to your CYD.

I hope this helps someone.
