The Interrupt PIN selected (GPIO 36) for T_IRQ is not a good choice. It will behave unreliably because only TOUCH pins are mapped to the ESP32 hardware MUX. You should select from available TOUCH0 to 9 inputs, respectively GPIO # 4,0,2,15,13,12,14,27,33,32

As Paul McWhorter would say: BOOM!

This works perfectly on my ESP-32 WROOM.

Thank you so much, Sara. I’ve only been programming Arduino projects for about 2 months, and during that time I’ve learned to ignore all the noise out there and come straight to you when I have an issue. You don’t just provide the answers, you teach your readers how and why things work. As someone who is eager to learn, I am grateful to have found you! Keep doing what you’re doing, and I will keep practicing so that some day I can become you!

You’re probably inserting the location in a wrong format.

It’s working :
…
#define GPIO21 21 //black screen
int prevState = LOW; //touch

In the loop :
….
// Screen ON or OFF when touch
if (touchscreen.tirqTouched() && touchscreen.touched()) {
int currState = digitalRead(GPIO21);
if(currState != prevState)
{
digitalWrite (GPIO21, LOW);
}
else { digitalWrite (GPIO21, HIGH);
prevState = currState;
}
}
…

If you look at the code from one of the other tutorials you should be able to do this.

https://randomnerdtutorials.com/cheap-yellow-display-esp32-2432s028r/

This has code for using the touch screen and adding the required library (XPT2046_Touchscreen.h) as well as the initialization code.

Touch detection is below…
if (touchscreen.tirqTouched() && touchscreen.touched())

And you can toggle the screen off and on by toggling the backlight I believe – Backlight Pin is GPIO 21.

Hello,
Thank you for this beautiful project that I made and adapted in French. I was wondering if there was a possibility to turn off the screen and turn it back on when we need with a simple touch?
Thank you
Best regards

Hello Sara

open-meteo.com seems to hate me and I get the following comment on the serial monitor: “GET request failed, error: read Timeout”

What am I doing wrong? Please help me.
