Internet radio and audio file player on ESP32-S3

MAJSTER XXL 294273 2810

TL;DR LABEL_AI_GENERATED

  • Built an ESP32-S3 internet radio with an audio file player and OLED desk display, evolving through v1, v2, and v3.
  • Uses an ESP32-S3-WROOM-1, PCM5102A DAC, rotary encoders, and GitHub-hosted station lists split into banks of up to 100 stations.
  • The prototype uses a 2.42" 128x64px white OLED display, with a PCB made in Poland costing 130zl.
  • v3 adds a colour screen, weather, a calendar, RSS news from Polsat News Polska, and full remote control.
  • The first PCB had a pad-spacing mistake for the ESP32-S3-WROOM-1, so the module pins had to be bent slightly to fit.

    This library is even faster than TFT_espi.
    The FPS has improved dramatically – 98 instead of the previous 37.
    Where exactly is the "DRAW_FPS" measurement taken, because it’s a bit "thin" here...
    Do you have four displays connected to the MCU?

    Not two ESP32 processors: the old program for the ST7789 and the new one for the NV3007. For now, I’m transferring the VU and style editing functions over – let’s see how it turns out.
    loopFrames – counter for the number of iterations of the main loop()
    audioFrames – counter for received audio frames / generator
    fftFrames – counter for FFT analyses performed or test frames
    drawFrames – counter for screen frames drawn

    I don't quite understand something.
    Loop and FFT – 98 FPS, but only 8 frames?

  • PAM8406 causes no sound and ESP resets

    Hello
    I’ve added a PAM8406 amplifier to the PCB from @DJCheester’s project, but unfortunately there’s no sound coming from the speakers.
    The volume is set to halfway; when I turn it up to maximum using the remote, the ESP resets after a short while.
    With the previous version of the PCB fitted with a PAM8403, there were no issues with sound coming from the speakers.
    What could be the problem? I’ve tried two PAM8406 amplifiers.

    Is there any sound coming from the PCM5102 output?

    Internet radio and audio file player on ESP32-S3

    There is sound on the PCM5102 and the radio connected to the stereo system is working normally.
    Voltage measured at the PAM pins is 4.4V; of course, the power supply wires to the PAM amplifier are connected to the board.
    Only a faint hum can be heard in the speaker.
    It looks as though the audio signal isn’t reaching the amplifier.

    EDIT:
    The problem has been solved; the Chinese manufacturer had soldered the pin header the wrong way round; once reversed, it worked.
    Here’s a photo for reference, so that anyone ordering this and experiencing a similar problem can check whether any pins have been soldered in the wrong way round.

    Are the pin descriptions incorrect? Because as far as I can see, all PAM8406s are mounted identically.

    I’ve just been looking at AliExpress, and in the photos they all have the pins facing upwards, just like in my photo.
    The best thing would be to buy one to solder on; that would sort the problem.
    When mounting the PR with the pins facing downwards, the Vcc, Gnd and speaker output pins are not reversed.

    Here is a description of how it is calculated:
    LOOP_FPS determines the speed of the main program loop and indicates how many times per second the entire control code is executed. A value of around 90–120 FPS indicates very good system performance. AUDIO_FPS determines the rate at which audio samples are retrieved and processed from the I2S interface. The higher the value, the faster the input signal is analysed and the more responsive the indicators are. FFT_FPS specifies the number of full FFT analyses performed per second. This parameter determines the speed at which spectrum data is updated and the levels of individual frequency bands are calculated. Values of around 80–100 FPS are very good and ensure smooth operation of the analyser. DRAW_FPS determines the speed at which graphics are drawn on the display. This is the number of full panel refreshes performed per second. In the case of the NV3007 configuration, DRAW_FPS is most often the main performance bottleneck. For example, with values of LOOP_FPS=92, AUDIO_FPS=86, FFT_FPS=86 and DRAW_FPS=14, this means that the processor has no problem retrieving audio data and performing FFT calculations, whilst the display is refreshed only 14 times per second. This results in jerky needle movement, less smooth bar movement, visualisation delays and the impression that the analyser is running more slowly, even though the audio section is functioning correctly. Therefore, when optimising the FFT panels, the greatest attention should be paid to increasing DRAW_FPS, limiting the number of graphics operations, reducing the number of full screen redraws, and updating only the elements that have changed. The target values for the NV3007 FFT analyser are LOOP_FPS 90–120, AUDIO_FPS 80–100, FFT_FPS 80–100 and DRAW_FPS a minimum of 25–40 FPS, which ensures smooth and stable operation of the entire system.

    This is the performance I am currently achieving:

    It ran at 30 fps on the output; there’s nothing to render there, which is why it runs so high. At 5 fps, the spectrum is full – full peaks, numbers and wider bars.

    Hello
    I’ve added a PAM8406 amplifier to the PCB for @DJCheester’s project, but unfortunately there’s no sound coming from the speakers.
    The volume is set to halfway; when I turn it up to maximum using the remote, the ESP resets after a short while.
    With the previous version of the PCB, which had a PAM8403 fitted, there were no problems with sound coming from the speakers.
    What could be the problem? I’ve tried two PAM8406 amplifiers:



    Hello everyone, I’ve been away for a bit – the PAM8406 is mounted on the PCB with the pins facing upwards. When buying the module, you need to re-solder the gold pins from the underside, i.e. beneath the PCB, so that when plugged into my radio PCB, the pins are on top.

    Could you take a photo of that PCB with the PAM8406 and add it to the thread? I designed that PCB but haven’t tested it myself.

    I don’t know which board the chap was using; versions 2.3, 3.3, 6.3 and 7.3 are available for the Pam 8406 amplifier.

    The Pam is mounted as shown in the 3D diagram

    Hello
    Where and on which line do I need to select the display type?

    Here’s your choice: you can choose the ILI9341 shown in the photo (currently selected) or the ILI9488; the ST7796 also works with this one Code screenshot showing #define EVO_PANEL_ILI9341 selected with TFT settings and Polish comments.

    I wanted to use SSD1322, but when I select this display, I get this error.
    With others, it compiles fine.

    This directive from line 86 is a bit odd.
    After selecting EVO_PANEL_SSD1322 earlier,
    the compiler should stop compiling.

    This software was tested for TFT screens – NOT OLED. If you have an OLED screen, you’ll need different software; this one probably won’t work.

    We’ve finally managed to get the EVO4 MULTI up and running.
    This is what it looks like now. The system consists of 4 ESP32 processors
    1. Evo3 internet radio project with graphics added for the TFT display
    2. A 12-band equaliser with a range of ±16dB
    DSP equaliser as a panel for the TFT display
    3. Spectrum and VU meters
    4. Bluetooth audio transmitter.
    The whole system operates via I2S.

    The combine harvester is top-notch, but I’m sticking with the basic version of the Robgold radio – the only thing I’m missing is the music player function. I’ve also connected the spectrum analyser from effiego222 via a RCA cable, and it looks great.

    Best regards....

    Could you give a bit more detail? What software and board (schematic) are you using? I must admit I’ve got a bit lost with all these versions, and I’d actually prefer the basic version. Thank you and best regards.

    Why not skip straight to the Evo5 then? Leave the Evo4 to ejcon 😀 The bloke’s had a right go with just the ESP and LCD 😀.

    Actually, it’s quite possible that a PCB ‘my way’ for ejcon’s Evo4 will be ready this autumn.

    Sorry, but I named it after the database I was using.
    I didn’t change the name because it isn’t entirely my own – just certain parts – and it’s called EVO4 MULTI because of the number of processors; there are 4 ESP32s.

    The ‘tape-less project’ has been around for a few years now – an old smartphone acting as a cassette, plugged into a cassette player or deck for old hi-fi systems.

LABEL_AI_GENERATED
Discussion of a DIY internet radio and SD-card audio player built on an ESP32-S3 with an OLED display, rotary encoders, buttons, and a front-panel interface. The project uses Wi‑Fi to download station lists from GitHub/public stream databases, supports MP3 and later AAC/FLAC playback, displays metadata including Polish characters via a modified font table, and stores settings such as station/bank selection and volume. The thread covers PCB design in EasyEDA, ESP32-S3 module pin spacing issues, PSRAM and Arduino IDE setup, library compatibility problems, SPI/I2S wiring, SD card reader boot issues, encoder behavior, WiFiManager-based network setup, and troubleshooting of crashes, HTTP download failures, and audio initialization errors. Several improvements were added over time, including station selection by encoder, time sync, browser update support, and saving settings to card memory.
