Hi Alan,
Thanks..
BTW: I found a minor mistake in my Touch Controller Adapter Board design, I
don't know (yet) how our touchscreen input driver handles PENIRQ\ (if it is
used), the R3 should normally be pull-up to Vcc but I connected it to GND by
mistake. I'll correct it.
Regards,

Hi Murat,
All you need to do is to define:
CONFIG_INPUT_TOUCHSCREEN (and enable your touchscreen driver)
and
CONFIG_EXAMPLES_LVGLDEMO_CALIBRATE
Your touchscreen device needs to be at /dev/input0
Look at apps/examples/lvgldemo, it is very straightforward.
If your touchscreen is not /dev/input
Hi @Barbiani,
I got a 3.2" resistive touch panel from Buydisplay, however I would like to use
it with ADS7843e controller using nuttx/drivers/input/ads7843e.c instead of
connecting it direct to ESP32 ADC inputs as you did, however I'm not
experienced enough in lvgl so I don't know how to make t

There are also capacitive touchpads with integrated controller like this:

@Barbiani you've made a great contribution, thanks.
Is this the correct product:
https://www.buydisplay.com/2-8-inch-4-wire-resistive-touch-screen-panel
It costs only $ 1,18,I think a very convenient price, their mailing fees are
also not expensive, they accept paypal and western union payment,
Actually this was not exact same thing what we need; we need a cheap touch
glass or film something like this one https://www.mikroe.com/touch-panel

Great news!
Which touch glass you placed over the display ? I would like to buy one
immediately.
Maybe the Nuttx-Fellows may consider to include this opportunity into the Nuttx

Hi,
I have put together a touch screen driver for this board using a separate
touch glass placed over the tft display.
It is resistive and the connections are described in the source file.

Hi Guys,
All is clear now, thanks for your interest and for the information provided.
Yes, I could disable the slideshow via
"CONFIG_EXAMPLES_LVGLDEMO_WIDGETS_SLIDESHOW".
I think a mouse input could be enough for this board.

Hi Murat,
Just to add to Alan's answer, this is actually the Slideshow mode for the
LVGL Widgets example.
You may disable it via "CONFIG_EXAMPLES_LVGLDEMO_WIDGETS_SLIDESHOW".
Then the example application will just wait for the user input.
Best regards,
Gustavo.

Hi Murat,
The LVGL moving up and down it not a bug, it is by design.
LVGL guys did it as as way to show all the screen exactly for board
that doesn't have a touchscreen to interact with it. Otherwise you
should think it was crashed/freeze, don't you? :-)
Hmm, maybe we can use a BackBerry TouchPa
Dear Gustavo,
Thanks you very much for your interested and for the informations you've
provided.
I wasn't aware that the esp-wrover-kit doesn't have any touch keypad, I am very
much surprised about that. That's why I talked about an improper lvgl
operation, I was expecting to interact with the

I've just watched your video after you made it public.
It seems to be working as expected for the "esp32-wrover-kit:lvgl"
configuration.
What exactly do you mean by frequency mismatch? I can see some stripes in
the video, but I believe this is probably due to the video recording.

Hi Murat,
Could you please enable debug info for the LCD category and share the logs
from the board initialization?
I've just tested here on my ESP-WROVER-KIT V4.1 unit and it seems to be
working fine with the latest nuttx and apps.
Best regards,
Gustavo.
