    • RE: T-watch s3 2020 codes ?

      @eliott I'm not sure about this product.
      Are you asking for the exact firmware that shipped with your watch when new?
      Here is a link to example sketches at the LilyGO repository:
      https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library/tree/master/examples
      To be sure, you may raise and "Issue" on this site, which may take a long time.
      I have found that a nice inquiry at their office address works:
      sales@lilygo.cc
      Also LilyGO suggest this GitHub repository:
      https://github.com/sharandac/My-TTGO-Watch
      Hope this helps!

      @luki743 said in CAN Transceiver Support:

      T-Embed

      Yes. ESP32 supports CAN and these are featured S3 boards.

    • RE: T-Beam SUPREME - Charging battery when off

      @luffe LilyGO products...generally yes, they charge all the time while plugged in to USB.
      You should conduct a simple test with your actual unit, as the documentation is very sparse.
      (I could not find a schematic for your board)

    • RE: How to operate T-Display-S3 Touch out of the box

      @danardi It is indeed annoying and it gave me trouble, but I figured out that you can edit the pinconfig.h that appears in the Arduino IDE off to the right with your own SSID and Password and avoid the ESPTouch nonsense. (this 'ESP touch" has nothing to do with the optional touch screen, BTW)
      If you are new to LilyGO T-Display S3 I made a support GitHub repository here:

    • RE: Is T-watch 2020 V3 water resistant?

      @ivan Hi Ivan, this site is a volunteer user community site and anything I say is simply "advice".
      LilyGO make no claim of waterproof, but it seems well sealed.
      I think accidental splashing such as washing hands would be OK.
      Otherwise I would "Damp-Cloth" it as you say!

    • RE: how much voltage required to run t-deck with battery input

      @abdnatsheh The Board needs 3.3V obviously, but the recommended battery is 4.2V type rechargeable only.

    • RE: Display removal, T-Display-S3

      @brekel
      Yes.
      The screen is held down with spongy two sided tape and the ribbon cable plugs into a connector on the board.
      You might soften the the tape with rubbing alcohol.
      They are very fragile.

    • RE: T-Deck pager firmware

      @ripple_biz
      Thank you for that link to the Adafruit ESP32 uploader.
      LilyGO has problems with forking the TFT_eSPI, LVGL and other libraries, so it is nice to be able to upload a .bin of a compiled 'good' program.

    • RE: T_Display S3 no wifi WPA conecct

      @thejaxco Ideally a (famous) 18650 type battery.
      But any rechargeable battery between 3.3V to 5V volts.

    • RE: Lilygo t-can485 spi connection

      @tiak See here!
      https://github.com/Xinyuan-LilyGO/T-CAN485
      The empty header next to the Power In socket has GPIO and so could be setup in your sketch as Standard Speed bit-banged SPI.
      You should pour over the pages of the Espressif documents for your ESP32 and see it any of them are High-Speed, etc

    • RE: Trouble flashing LoRa32 V2.1_1.6 (Paxcountrer) with new code

      @crisant Right away I don't recommend the blank Arduino IDE "New Sketch" without something for it to do, such as a delay(100);.
      People have found that they cannot connect afterwards because of the short scan time not allowing any other activity!
      I made this sketch to test that the board is working by printing to the serial port:

      //words preceded by "//"" are comments and are not executed
      bool ticktock; //declare ticktock as a boolean flag
      
      void setup() {          //runs once on start up
      Serial.begin (115200); //open the serial port for USB cable
      }
      
      void loop() {         //runs in circles!
      ticktock = !ticktock; //every pass through reverse the flag
        if (ticktock) {     //test current value of the ticktock flag
          Serial.println("tick");  
        } else {             //prints one or the other to the USB port
          Serial.println("tock");
        }
      delay (1000);           //wait for a second and run again!
      }
      

      I went to their GitHub repository for uploading instructions and they are different than a normal ESP32
      https://github.com/LilyGO/ESP32-Paxcounter#uploading
      so try following their ESP32 with LORA instructions

      Also when you pull down the board type menu in Arduino IDE where you select your board type, there is also the available ports.
      Check to see that the USBmodem is stable.
      Sometimes when I get the Failed Uploading error I have to reboot my computer. This has been a "bug" I have faced for years.

    • RE: Display removal, T-Display-S3

      @brekel I don't have a touch screen LilyGO T-Display S3.
      Even the the LCD cable would be a stretch to extend 10mm, and again that 10mm would require a lateral displacement offset of the LCD relative to the PCB, like a Z.

    • RE: T-Display-S3 and JST Pin 43

      @patofoto Well, it took months and months but finally some guys over on the GitHub for ESP-Arduino finally found it!
      https://github.com/espressif/arduino-esp32/issues/8324#issuecomment-1725784617
      The helper util file in the onewire lib had an outdated notion that there could not possibly be pins greater that 33.
      I edited mine and now it works!
      Wow, what a ride!

      @teastain2 OK, so I made this as a starter for you, but I cannot do the entire project!
      Give me your email address and I will send you the program.
