    Where can I find all the OLED screen drivers implemented for the radio? Because an OLED bargain on a ssd 1362 3.12" 256x64 jumped out at me. When buying 3 they come out at £45 each.

    What was mentioned anyone can do for themselves in 1 minute.
    Write the codes in any .h file and pull it into ino.
    The .h file itself should be in the directory with the .ino, and the Arduino will even pull it into the editor, when started.

    Nothing the colleague has contributed to the discussion.... That's probably how we manage - well 200 peasants each time we update spend one minute on this very operation. That's 200 minutes... And if he forgets, nothing happens, but the waste of time is greater, because in order for the own pilot to work you have to perform the operation and wait for the compilation - and this takes another minute maybe two. We multiply this by the number of colleagues who want their own remote control.

    Or maybe a colleague could add voice control - OK nabu, google .... set the station "Radio Drivers"

    Gentlemen, I don't see a problem here, as my colleague Robgold makes the sources available and also explains to everyone how to compile it, so anyone can do it, after all, updates are not made every day, and those who do something with the code on their own probably compile and upload their own patches more than once anyway.

    I'll add that I have an old computer and it takes me 10 minutes to compile it, but in this time I usually do something else.

    I have the pilot codes saved in a txt file and all I have to do is replace all the lines by pasting in my own.

    For me, the project is of value because I have more than 30 years of experience in electronics, tubes, transistors, linear and digital integrated circuits, microprocessors and now ESP or microcomputers.

    I never thought that the average home electronics technician would be making such devices, electronics has always surprised me over the 30 years that there has always been something new and better, which is why I'm so into it, by the way, I'm curious to know what devices and projects will be within the reach of the home robot in 10-20 years.

    Greetings to all...

    @DJCheester In 10 or 20 years this electronics and displays will be imprinted into the casing, and powered by electromagnetic smog (wirelessly) like all those transponder tags.

    Brilliantly said ;-) It has indeed progressed unimaginably.... Yesterday I was running the OTTO robot on esp32C3.... wouldn't compile because the servo was only written to AVR.... I make a plea to AI and she corrected the library headers for me (adjusted for ESP32) (I changed the pin names myself somewhere in the code and the robot ran. My son comes home from school today and asks if we can produce these robots because 5 classmates have placed orders with him..... (and this is first class....)
    Rysin - you're probably right - the next ten years could be the biggest breakthrough we will experience and programs will be written for us by AI based on intelligence..... Unless the Russkies keep us busy with another job.....

    Added after 4 [hours] 18 [minutes]:

    does the update in recovery not work? I have huge partitions without OTA - maybe it's a bug and it has to be marked to be OTA?
    At the beginning of the upload of a new bin, it resets itself with the attachments as with a reset.

    @wirbud To update via OTA, you need an OTA partition.

    @robgold in displayMode 2, third line overlaps line above bitrate info, clock etc.

    Just change the line:
    yPosition += 12; // Shift down for next line.

    at

    yPosition += 11; // Shift down for the next line

    @sharyczlowiek83
    We are using the u8g2 library. You can find all the displays in the examples in Arduino or on the library author's GitHub.

    @DJCheester
    I compile with the "spiffs 3MB App/1.5MB SPIFFS" setting. There must be somewhere to put this bin file.

    @hevet
    There is an option with that 3rd line because I couldn't find a radio willing to transmit such a long stationString during testing. So this needs to be corrected. I see that you like this 3-line mode :) I would raise the whole -> int yPosition = 25; instead of squeezing the text to 11px per line. With Polish characters it will be barely legible.

    Responding to the pilot topic.
    "Throwing" the pilot into the h-file will not solve the problem because compilation of the code will still be required. I would like it to be possible to load the finished bin file and any settings would be pulled from the SD card.

    @hevet Actually Radio Łódź uses "StationString" to the maximum. Only somehow the Polish "stamps" don't decode.

    @robgold PR Łódź doesn't transmit Polish characters as far as I can see, they don't show up in foobar either.

    This is a mistake on the part of the station, because their other station, Radio Łódź nad Wartą, already has the Polish diacritics correctly set.

    With these Polish characters it is sometimes a massacre. Radio Zet doesn't know what standard it uses, it used to be able to have in one word, one Polish character fine, the other already some kind of bush. Although recently I think it's finally getting it right. Radio Toruń, also had some strange coding. Radio Żnin, also has some bush instead of Ż in stationString....

    Gentlemen I have bought a 5.5 inch OLED and an ESP32-S3 Uno


    ESP32-S3 kit with OLED display on a desk. .

    I have already designed a PCB version 2.0 as an overlay on the ESP controlled only by remote control and via the ;) page.

    This is how it will look like

    3D render of a PCB board with electronic components visible from the side.
    Close-up view of a purple PCB with electronic components. .

    This ESP alone for just over 20£ at the Chinese is well worth it. For commissioning you need the CH341 controller, besides that the code of the colleague Robgold is loaded onto the board without any problems.

    After uploading and configuring the hotspot, the radio on the ESP alone starts 😀

    This is evidenced by the log in the serial monitor.
    Screen capture of debugging logs on a Samsung laptop monitor. .

    Cool radio will be for the workshop big OLED + this ESP.

    The only thing is that there is no resistor 0 from the RGB diode and you will have to get rid of it eventually, because it gives the eyes.

    Best regards...

    So there is a converter and sd ?

    Well, but for our radio it's not going to be useful anyway, there's no way to rig it up yourself and connect it.

    @DJCheester There's a whole audio player in there, only communication is via SPI. Practical Electronics have made an internet radio out of this on their board of course, along with the ESP32S3.

    Only on this overlay is the VS1053B codec, not PCM5102, useless for this radio.

    Under this programme it is certainly not suitable.

    @DJCheester Connect this display. I'm curious to see the effect. I think it's the same SSD1322 controller.

    DJCheester

    I'm also curious about the effect of the controller being the same, so far that much I know is also supposed to be green. As I find some time on my next visit to the workshop.

    Of course when I get it working I'll take pictures, the controller is the same as in 3.12 so I just need to rewire and solder the wires, this time I want to make it into a JST 7pin plug. This is how I have it designed in the PCB of this overlay.

    Hi you can buy this large OLED, you just need to remove the 10k resistor marked below to run the OLED in SPI mode

    OLED PCB with a marked 10k resistor to be removed.

    I have connected the display to the programmed ESP S3 UNO

    ESP S3 UNO board connected to various cables and USB power.

    Radio running in cardless mode.

    Electronic setup with a large OLED display showing an SD card error message. .
    Two OLED displays, one larger and one smaller, connected to an ESP S3 UNO microcontroller on a table. .

    For comparison, my previous radio in pictures with OLED 3.12

    The display was a bit expensive but I think it is worth it.

    Same resolution so up close a bit big pixels but in my case the OLED will be installed high up so from a distance it will look nice.

    It's on the same driver as the OLED 3.12 so nothing in the code needs to be changed just connect the pins correctly and the 5V power supply.

    Regards...

    Here's what I'm wondering... Why would anyone need such a large display in such an application?
    By the way, does anyone have a datasheet for this 3.12"? I can't find any that make sense, and the ones in the auctions are only cursory and poorly readable.

    .

    Well you need it because it will be viewed from about 7 metres and that's why the version of the radio being made now has no encoder just ir and Web for control.

    I have the datasheet and schematic on my computer I will look for it and send it when I am at my computer.

    There is one small problem with these oleds, they are not suitable for continuous operation, the matrix will burn out where there are fairly constant pixels displayed and nothing will be seen. This is why I have weaned myself off this type of lcd :) .

    You can't stop progress, I remember the first LCDs had this with the bars at the bottom with the news. they came up with moving the image by 1pixel randomly by the processor and solved the problem. Looking at the prices of small OLEDs, you can say that the problem is insignificant.

    Well yes, as usual you have to cling to words, typical.
    So maybe I'll clarify, it's about the display commonly referred to as LCD, I have your permission to use such a synonym ? thank you in advance :)

    I completely agree with you :) however these OLEDs from this project are no longer so cheap :)
