    From Robgold's Github you download the swap files and swap he in the original library folder in the SRC directory. In my case it works after swapping.

    Do you already have the libesp_netif and liblwip files swapped ?

    Thanks 👍 for your help.
    Everything won beautifully only stations from bank 16 basically can't be listened to terribly cuts despite super wifi signal.
    Any ideas?

    I wrote above the question if the colleague has swapped these files ?

    They are for FLAC playback, the FLAC streams get cut on the original ones.

    Hello.
    Yes I have replaced the files.

    But in the right place you substituted ?

    C:\Users\user\AppData\Local\Arduino15\packages\esp32\tools\esp32-arduino-libs\idf-release_v5.4-2f7dcd86-v1\esp32s3\lib

    These you should replace here.

    Only instead of user is your computer name ?

    It plays fine with me after this swap.

    Welcome,

    i have uploaded to GitHub Dzikakuna version Evo 3.19.19
    Link

    What's new ?
    - improved bitrate reading for stations where the bitrate is calculated by the library (so-called estimated bitrate)
    - in displayMode 4 I added such a mini logo with information about the codec and bitrate
    - in the menu for displaying the list of stations, quick navigation has been added.
    Now, pressing the right and left arrows jumps by 5 stations. The up/down arrows switch by +/- one station as before.
    - the function of switching the radio on/off from the remote control, so called POWER OFF/ON, has appeared.
    In this mode, under the rcCmdRed button (eventually there will be a dedicated code rcCmdPwr) Pressing the button once, the radio goes into Standby mode, the ESP32 goes into light sleep mode minimising current consumption (on a mini USB meter it is 0.00mA). To wake up the radio press the rcCmdRed button (red handset on the RC-406) 2x at an interval of less than 0.5sec. The first pulse wakes up the ESP32 and the second pulse is only read correctly in the interrupts and the button code is checked. If the code is correct, the radio displays POWER ON and then performs a reset and starts. If the code is wrong the radio immediately goes to sleep without showing anything on the display. Eventually this will be linked to a standby LED and a transistor to cut off the card, display, PCMa, possibly other peripherals.

    Very good that there is a standby, it will certainly be useful for my final version of the radio in the Schneider tuner housing.

    I am already sitting down to upload the new version.

    This button you used for standby is it new - added to the list ? Or currently already in use ?

    @hevet This is the visualisation I came up with, The "cathode ray tube" animation can be turned off in the prePowerOff function.

    @DJCheester the "powerOff" function is assigned the "red handset" button from the Kenwood remote control.

    I've been browsing the remote control market a bit in general, what could be a better fit at little cost. I found these two interesting remotes:

    My colleague @hevet dropped me a prepared library with support for Polish characters in the FreeSans12pt7b font for testing. I've thrown this into my v3 version for now in the file player and the effect is as in the screens below. I also added display of the wav format. (Hardly anyone uses this these days). I took the liberty of uploading this file with Polish characters to my repo on github, thank you Fellow @hevet .

    Hello, the radio is developing beautifully, I mean both projects of kol. Robgold as well as the version in colour of kol. MajstraXXL ;)
    As I have been using the Robgold version of the radio for a long time, I wanted to put together a second receiver, this time in colour ;)

    I designed a PCB for the connections of coll. MajstraXXL according to the schematic he provides on his Github.
    The board is designed in my style i.e. on modules and in a through-hole version.

    PCB looks like this ;)

    3D render of a green PCB labeled for ESP32-S3, PCM5102A, and PAM8403 module installation
    3D render of a green single-sided PCB with through-holes and circuit traces

    And this is how the 3D render looks ;)

    3D render of a PCB with ESP32-S3, PCM5102A and optional PAM8403 modules
    Green PCB with visible traces and mounting holes, 3D rendering

    The PCB design includes the necessary modules i.e. ESP32-S3, PCM5102A, SD module, and optional PAM8403 amplifier module.

    Once the prototype version is up and running I will make the project files and gerber available to others ;)

    Regards ...

    I would like to ask the author and my friends who understand this subject, to which offset address should I load the ESP32_radio_evo3.19.17.bin file with the Flash loader for internet radio? I tried 0x0, it loads but the screen does not appear. When I compiled it with Arduino IDE 2.3.4 ESP32 Core 3.3.2 without any errors and uploaded it to the ESP32 S3 Module, I can see it as EVO-Radio from WiFi, but the screen remains black. I have an SSD1322 display, and the display works with yoRadio. My display connection pins are SCK-Pin38 SDA-Pin39 RST-Pin41 DC-Pin40 CS-Pin42, I kindly ask for your help in this matter. Best regards. My English is very bad, please excuse me.

    The pins are correct, if it's an OLED display 3.12 whole (that's the one I have) then there are several reasons.

    1. The 5v power supply and gnd are they connected to the display ?
    2. Is there the required voltage on the 5v pin ?
    3. Is the SPI interface set up correctly.

    These two resistors on the display should be soldered like this ?

    If everything is as it should be and it doesn't work then from attaching the photo maybe we can find out what is wrong ?

    Gentlemen someone once wrote (or it seemed to me)

    I've been thinking and thinking - I want to order an LCD display.

    Foreman XXL sent me a link to an LCD where he was buying

    https://sklep.msalamon.pl/produkt/wyswietlacz-tft-lcd-35%e2%80%b3-ili9488-320x480/

    There is an SD card reader on this display.

    Has anyone run it with our radio ?

    Because if so and it works I will add an optional JST connector in the PCB design for the SD_CS, SD_MOSI, SD_MISO, SD_SCK pins ?

    Then it will be possible to dispense with the microSD card module.

    Oh and a final issue MAJSTER is 3.5 inches in size, to this size in width I will adapt the board.

    There is also a 4 inch LCD

    https://pl.aliexpress.com/item/1005003033844928.html

    Will this larger one also work ?

    Greetings ...

    Added after 1 [hour] 40 [minutes]:

    I changed the PCB so that the size between the holes is 92mm. I found the dimensions of the 3.5 inch module on the internet.

    MajsterXXL just confirm to me how you can the dimension between the holes on the display board ??

    Greetings ...

    @MAJSTER XXL I've already embraced, got the card working on the display, but had to remove three resistors on the lines from the card.


    @hevet does this LCD reader work stably after removing these resistors ?

    Well, I have improved the design - adding a connector for an SD card placed on the display.

    Tomorrow I'll check the connections to make sure I didn't screw up when making the PCB and make a gerber.

    Well done ;)

    Checked connections ;)

    I added the numbers next to the JST connectors corresponding to the display pins.

    This is how it looks ;)

    I also bought the missing components today - I'm assembling the PCB tomorrow, I have the modules, the display from Salamon is already on its way to me.

    So there will be a launch soon, and if it goes well I will post a gerber for those who are interested.

    I have assembled this internet radio, it plays beautifully. I used the software from robgold version 3.18.21.
    Today I wanted to upload the newer version 3.19 so I installed the recommended libraries via robgold. I just can't add the Audio_i2s library from github because the error shown in the picture appears. Is this library added differently?

    The libraries are in the user name userDocumentsArduinolibraries and there is a directory "ESP32-audioI@S-master" where you need to replace the SRC content. You download the corrected files from kol.Robgold's Github.

    @robgold I would like to make the case like this😀. Case bought from modushop.co.uk specifically Link . Front panel + plexiglass for the holes for the display and IR receiver made on cnc also in this shop (they also do custom machining). I drew the panel in eagle including the lettering (which they burn out with a laser) and emailed it to them. Cost approx. 365 PLN (enclosure + processing) is a bit painful, but if it is to look good, it is worth paying. As you can see with me there are two encoders because originally there was supposed to be a soft XXL from the master, but he offered me yours and so it stayed. The second one will now be for decoration😀. A couple of pictures of my creations:

    @wieh76 It came out very nicely. I for one am a believer that it's better to have something you enjoy than to save up and then be upset that it's not. It came out SUPER. I'd get that second encoder in the software and make it into two: Volume on one, stations and banks on the other. I wonder if I should go back to such an option in the Evo so that someone who wants a version with two decoders could configure it that way.

    Are you planning to share the file for the CNC front end ? Question how is the display mounted/glued ?
    What do you have a small arduino for in this project ?

Topic summary

The discussion centers on the development of an internet radio and audio file player based on the ESP32-S3-WROOM-1 module, featuring a custom-designed prototype PCB with OLED display and user controls including rotary encoders and buttons. Key challenges addressed include pin spacing discrepancies in the ESP32-S3 module footprint, integration of Wi-Fi connectivity with dynamic station list updates, and handling of Polish character encoding on the OLED display. The project uses Arduino IDE (version 2.3.2) with ESP-IDF support and requires enabling PSRAM. Audio playback supports MP3, AAC, and FLAC streams, with the ESP32-audioI2S library recommended over the incompatible Audio library. Users reported issues with SPI MISO pin assignment causing bootloader conflicts, resolved by reassigning MISO to pin 35. The project incorporates WiFiManager for network configuration, EEPROM and SD card storage for saving last played station and settings, and includes plans for tone control via an external KA2107 equalizer and a CS8673 amplifier module. Problems with encoder input stability and memory limitations for Bluetooth A2DP on ESP32-S3 were noted. The community suggested alternatives like KaRadio and ESP32-MiniWebRadio projects. Debugging tips include serial terminal logs for HTTP errors and flash memory erasure to resolve boot loops. The project is open-source on GitHub, encouraging forks and modifications. Additional features under development include browser-based updates, directory navigation, and potential audio recording to SD card.
