Hi guys I have a code that shows in the tft display 2 temperatures, but when I click in a specific area I want to overlap them separately, but when I click in the specific area the screen refresh and both temperatures (that wasnt in the screen before) just apear at the same time.

Note: "criarBotao" means create a square.

Are you certain these lines need to be in "loop()"? The "touchscreen.h" example configures those pins in the object instance creation...

Humm let me see

4

Nothing changed

5

Put print statements in setup() (entering and exiting) to see if your mcu is resetting and starting from zero, or if the sketch stays in loop()

6

I tried it and it didn't work, it's a problem with the "if" and "else"

7

What did not work? If the print statements did not work, that means you have not uploaded the sketch.
