      Hello,
      I was looking for how to get an additional serial port and after many tests it turned out that "serial1" works on pins 16 and 17. This is not included in the Pins description in github.
      However, I had another problem because the normal "Serial.print("TXT");" it did not send me a serial monitor (USB).
      I thought maybe USB was connected to Serial2...
      After entering the Serial2 commands into the program and sending them to Flash, the program started, but the USB lost connection to the computer. The connection is visible in the "USB-Controller" item as an unknown connection.
      I don't know how to restore default now without using USB. please help because now my T-display-ESP32-S3 is useless.
      best Regards
      RomanF

        @romanf Hi!
        We have all "bricked" our T-Display S3 at some point, so I made a setup and example GitHub repository. The LilyGO T-Display S3 is a very advanced board, but poorly supported by LilyGO, the schematic is a confusing mess.

        (The TFT display is one of the first small LCD to be 8bit parallel interface, not SPI as the library name implies. This means that you can only use the supplied TFT_eSPI driver and can never do an Arduino Library Update on it.)

        I encourage you to follow it step by step and try running the demo sketch "LilyGO_HotHead.ino" to make sure.
        Also: both example sketches are very "tutorial" for learning ESP32 and sprites.

          TFT_eSPI
          hello Teastain,
          I have a question about Serial (the standard connection to the computer). serial.begin(9600); and Serial.println("Test");
          unfortunately on this module using the commands serial does not receive text on the serial monitor.
          do i need to use some other command?
          It needs software Debugging. I've never had such a problem before. I noticed that other ESP32 modules at startup even give their configuration and Lily-t-Display-S3 does not send anything.?
          Can you give me an idea of what it could be - maybe something is shifted in the TFT_eSPI driver?.

          Best regards and happy new year 2023!
