    I have uploaded this new firmware Evo 3.20.04 MOD, the radio starts up, WiFi address 192.168.4.1, the computer connects and the page to give the router address cannot be displayed. Apart from that it is terribly muddy, nothing works here. Maybe I am doing something wrong. I upload other firmware and they behave normally, everything laughs.

    See this bin, but if it goes into the page, it means that the bin was uploaded wrongly, with what do you upload?

    I've already uploaded so many times and different ones never had any problems.
    I will upload immediately and write what came out of it.

    The 192.168.4.1 page is not reporting ?

    Ejcon probably specified a bin to be uploaded via OTA.

    Win Robgold's soft as you write that it laughs and through the site via ota win ejcon's bin.

    Also, start using ESP Flash Download Tool to upload to ESP.

    This is the Wifi manager page and for it to work you need another device (phone/computer) to connect to the Radio-evo hotspot which the radio puts out as it cannot find the configured router.

    If you have had anything on ESP before, he suggests cleaning SPIFFS.

    I have also uploaded the ESP Flash Download Tool and it does not work
    But the ejcona bin works

    It's which bin doesn't work for you because I don't know now you've stated that it doesn't work and pointed to a post with ejcon content and now you're writing that it works.

    Describe exactly the problem, what are you winning like whether it compiles are or not and not one sentence answer it will be easier to guess.

    ESP32_radio_evo3.20.04. works loads the page through the browser and on the other hand this EVO 3.20.04MOD CAL does not work.

    @hevet any chance of getting the radio code from you ?

    Hi, I am not sure, but on GPI0 18 v verzija Robgold 3.20.04 there is no control, there is fixed 0,3V.

    Standby LED
    The standby LED has an additional functionality. As in equipment from e.g: Marantz, Denon it flashes during start-up, as the radio already opens the preset bank and starts playing stream the LED goes out. If for some reason we do not have a WiFi connection, the LED will start flashing quickly to inform us of the problem. Apart from this, the standard function of the standby LED is that it lights up when the radio enters power OFF mode.

    At my place it flashes during start-up, then remains on steady as I press the remote control button. v StANBY-POWER OFF nesvjeczi.
    What is needed to make it work as you describe?

    >>21858802 @DJCheester I'm not convinced that you can't use for compiling Majster libraries to FLAC. Especially as I now compile them myself and I know that it agrees correctly the core number with the number from which the library was recompiled. I will download the Majster soft and check it out then this library swap seems unjustified.

    @supsak
    There is no control on GPIO18 in Evo as of today. Perhaps colleague Ejcon added something in his version I will only add it.

    In OLED a resistor MAXIMUM of 2.2 Ohms and 1-1.5 Ohms is recommended.
    Start by adding 10 Ohm in the DAC power supply ground. Raising the converter ground will always have a negative effect on the converter voltage.

    Hi.
    I have now a 10 ohm resistor to ground on the OLED-display, I think it is too much... I have to change the VU meter is no longer visible, it flashes, switching on the banks is not correct.

    Now with your modifications it may be fine I have to check it out, but before when I had your files the Majster soft compiled uploaded but took a few minutes to connect or didn't connect at all and didn't download the stream.

    Now if it's good you can actually have the swap permanently.

    Fellows for a very long time I used the software 3.18.13 of my colleague @robgold not long ago I uploaded 3.19.70 , and now 3.20.04 unfortunately in the first sofet after a certain time stopped to be detected SD card and in these subsequent is the same.
    The reader and the card is working when connected to the receiver with @MAJSTER XXL's software reads from the SD card and I don't know what could be the reason for not detecting SD cards in @robgold's sofet.
    Question in the new 3.20.04 firmware I would like to enable the ADC keyboard option to control instead of the encoder with up-down, forward-back arrows , OK , and 3 buttons e.g. to store 3 stations , I am using the board of colleague @DJCheester
    Is it possible to connect an ADC keyboard on @DJCheester board with one encoder?

    This is how you connect 3v3 GPIO9 and GND and the keyboard will work.
    There is no pin out on a separate socket.

    As for the card you probably have disabled in the software when compiling, do you win the bin files or compile yourself ?

    Greetings ...

    The latest soft 3.20.04 j and 3.18.13 were compiled and uploaded in Arduino, while 3.17.70 was uploaded from a bin file.
    As for the keyboard because I haven't played with it yet, I'm doing a grid on the resistors?

    As for the keyboard not enough people use it/ leds are in the latest project ;)
    It is possible that also the keyboard will be released in the end it is JST 3-pin only

    I have not used a keyboard so far either, and it would have been easier to connect to JST 3 instead of making a spider.
    As for the leds, it's true, they are in the latest design and probably some people will use this option.

    Best regards...

    There is a designed LED and a power button.
    In addition, potentiometers on the input of the PAM8403 because the signal is currently too high.

    >>21861062 As of this software version, the AUTOSTORAGE function has been introduced. You have to define manually in the configuration whether you want to use an SD card or SPIFFS memory or both at the same time and the radio should automatically detect the card.

    Code: C / C++
    Log in, to see the code


    If you are 100% sure that you will always use an SD card then you can set as below:

    Code: C / C++
    Log in, to see the code


    The BIN file you have on GitHub is compiled under SSD1322 display, 1x encoder, AS-AutoStorage enabled. SD card should work 100% on it -> ESP32_radio_evo3.20.04_SSD1322_1ENC_AS.bin


    For the keyboard to work you still need a 22-24k PULLUP resistor on the input and a 100nF capacitor to ground.
    The ADC input is GPIO 9 as below. The keypad itself needs to be enabled in the radio settings.
    Code: C / C++
    Log in, to see the code


    Since version 3.20.04 there are presets, you can program in each bank the first stations from 1-10 as your favourites and with one click on the buttons 0-9 the radio will select the appropriate station. The presets function must also be activated in the radio settings.

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.
