  Hi, I don't find how "correct" configure the Arduino IDE, to use the full memory including PSRAM of the device.
  Setting it like a generic ESP32 its not valid. This one, includes the ESP32-WROVER-E MCU with 8Mb of PSRAM and 16Flash.

  Selecting a ESP32-WROVER and executing this code ...

  log_d("Total heap: %d", ESP.getHeapSize());
  log_d("Free heap: %d", ESP.getFreeHeap());
  log_d("Total PSRAM: %d", ESP.getPsramSize());
  log_d("Free PSRAM: %d", ESP.getFreePsram());

  The console output is ...

  [D][WifLib.ino:15] setup(): Total heap: 343784
  [D][WifLib.ino:16] setup(): Free heap: 317564
  [D][WifLib.ino:17] setup(): Total PSRAM: 4194252
  [D][WifLib.ino:18] setup(): Free PSRAM: 4194252

  Thanks.

  The ESP is ...

  Hi all,

  I am missing the 3D file of the case, which matches the LilyGo T5 4,7 inch together with the rectangular capacitative touch pad cover.
  Unfortunately there is no case uploaded. Neither for flat PH 2.0 nor 18650 battery version is available.

  Official channel:
  https://github.com/Xinyuan-LilyGO/LilyGo-EPD47/tree/master/3D_file

  Could someone please share the link to the file with me?
  I would like to print a housing for the LilyGo T5 4,7 with having the rectangular touch screen attached,

  Thank you very much

  Best regards,
  Joan

  @alveron Sometimes...this depends on the sketch that is running and other Arduino environment conditions...you need to manually enter Upload Mode.
  Press both Reset and Boot and release the reset first. You will lose the Arduino serial com and you need to re-select it.
  Once you have a stable environment it may not require the sequence, just Upload!
  You must select USB CDC On Boot: "Enabled" to get serial from your sketch to your computer.
  ADC in ESP32 is very poor. I don't have a T7-S3 to test, just check the Diagram and other Internet sources. There will be data noise and poor accuracy.

  @vintageslots The factory test code reads the voltage. https://github.com/Xinyuan-LilyGO/TTGO-T-Display/blob/master/TFT_eSPI/examples/FactoryTest/FactoryTest.ino
