Help making ESP32-3248S035 work

That just means your build machine ran out of RAM. I presume you’re running the ESPHome addon in HA, you need more RAM. Build
on your desktop or laptop instead.

Hi @makeitworktech

Good that you got it to work.

I also have another working example for resistive touch.

The reason that no entities show up in Home assistant is that no entities are defined in the display yaml.

Try to declare at text sensor like this:

text_sensor:
  - platform: template
    name: "My Text"
    id: my_text_sensor

When the dropdown selection changes, on_value is triggered and the selected text is returned in x,

Update then your text sensor when the dropdown selection changes by adding the following code to your dropdown code:

on_value:
  - text_sensor.template.publish:
        id: my_text_sensor
        state: !lambda return x;

Please let me know if you got it working

If you like, tell me about your plan for the display, what do you want to display, interact, get values from Home Assistant ad send values back to Home assistant etc. and I might be able to help you further.

Which model did you select for the OpenHasp firmware on this display?

I’m sorry I can’t remember. I’ve been happily using esphome for a while now.

Hey, sorry I missed this. I made a lot of progress. I documented it all here:

Well done, Sir! Well done. I was having issues getting the 3.5" touch screen work for a ESP32-3248S035C when comparing the config i did have working on a 2.8" ESP32-2432S028R.
The lesson is…apparently… not all CYD’s are created equal…lol. No reason we should assume they are.
But again…thanks man! Been messing with this one on and off for a couple of days now before being smart… and checking the forum. I LOVE…this community!
Cheers and Kudos!

ok, eventually got it to fully work (was not working on it for a few months). Without LVGL.

See full example on: cyd-tiled-display/esphome/lib/3248s035_base.yaml at ece3d49f14a382a9b185499f9418e65c31db9849 · yatush/cyd-tiled-display · GitHub

Thanks all for all the help!
