@aravecchia Try changing the initialisation string from tft.init(135, 240); to tft.init(); or tft.begin(); and add TFT_eSPI tft = TFT_eSPI(135,240); between your include and define declerations.
@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.
Finaly I find a solution.
My problem was probably an invalid application.
I have reinstalled hello_word program with a right bootloader, following pages :
I mean press and hold left button, press Reset button on the side while keep hold left button. Wait 2 - 3 sec until computer recognize your device.
Then select Port in IDE and upload scetch.
(left button as looking from USB port perspective)
