Brent Story asked 6 days ago

after loading the sketch for 1.9 the screen goes to:
      X=-294
      Y=714
      z=4095
and it just stays there. does not register any input.
when I go to the serial monitor this is what it is scrolling nonstop:
[Warn] (0.660, +30) indev_pointer_proc: X is 714 which is greater than hor. res lv_indev.c:692
i have dug through the forums both here and elsewhere looking for a fix but have not come up with anything have checked and double checked components and files. what am i missing?

Hi.
How does your CYD board look like?
Does it look exactly like ours? Or does it have two USB ports?
 
Are you sure you have e resistive touchscreen display? Isn’t it capacitive?

this is what i got:
2PCS 2.8″ inch ESP32 Display, ESP32 Module ESP32-2432S028R WiFi+BT Dual-core TFT Module ILI9341 Driver for Arduino IoT, ESP32 Development Board 240X320 Smart LCD Display Screen
but the back of the board does not have the “R” designation.

ok got it working., I had to go back and run it in the Arduino IDE. I have been using VSCode. 
 
What’s the difference?

Hi.
I’m sorry for taking so long to get back to your.
 
There shouldn’t be any difference if VS Code is set up correctly.
But, VS Code might be using a different ESP32 core version, a different LVGL or TFT_eSPI library versions.
Additionally, with VS Code, you need to configure the User_Setup and lvgl_conf files for every new project you want to build. If you don’t do that, the code might not compile or not work as expected.
