Display touch doesn't work properly

[linoreale]

Hi everyone,
I built the miniweb radio based on your project and it works, but there's a problem with display's touch system.
I'm using a ESP32-S3 N16R8 board and an ILI9488 display. On system boot it shows esp web radio logo and then last radio starts playng, but touch screen doesn't respond correctly, if I touch an icon, the led on esp board blinks but no action happens or wrong action or function starts.
Could it be a display problem, a wrong wiring or a known software problem?
Thanks and regards

Michele

richtige TP_VERSION, TP_ROTATION, TP_H_MIRROR, TP_V_MIRROR in common.h ?
Bei ILI9488 TP_VERSION auf 4 setzen. Standard ist 5 (ST7796)

Hi skassel2024,
yes, I set 4 for ILI9488 and left other as default.
What can I try in addition?
Thanks and regards

Some displays have a design flaw, maybe it's the same with your display?

linoreale, Try installing the touchpad version from a different display, such as ILI9486

Okay,
so, have I try to disconnect TFT_DC or TFT_CS pin?
Thanks a lot to you all!
Regards

linoreale, TFT_DC and TFT_CS do not need to be disabled

Hi,
on common.h I modified all the availlable variables but it's still not working. Screen shows images correctly but it seems touch pad is rotated on 90 degrees and no option modfies this.
Tried setting different display, rotation mirror and so on but it doesn't woek
what can I try again?
above my commn.h

linoreale, and have you tried this combination TFT_ROTATION 1 and define TP_ROTATION 3
or TFT_ROTATION 3 and define TP_ROTATION 1 ?

[valera39]

Do you have the same display?

I have the same display and it requires non-standard combinations of touchpad and orientation settings

[linoreale]

Hi valera39,
It seems the same.
Anyway, have I change values in common.h , build , compile and upload each time?
Thanks a lot, I'll try you suggestion.
Regards

[valera39]

linoreale, Yes, exactly like that, change one parameter, compile, test. If it doesn't fit, change it again and so on until we get what we need.
I also fiddled with such a display for a long time until I set it up correctly :)
I don't buy such displays anymore
Good luck!

[valera39]

linoreale. Here I found in my archive common.h from the second version of the radio with such display. Try it, maybe it will help

Hi,
I tried all availlable displays in the code list but touch panel doesn't still work properly, it remains 90° rotated, even though I set rotation 1 or 3 on each display version.
What else can I try? Is there something else to change in the code?
What display version works for sure, so I buy it?
Thanks and regards

[linoreale]

Hi,
I'm wondering if there are any other tp_rotation option to use in addition to provided options or if it's possible to use other display drivers in the code
