I can build it and the speaker plays music in English, but talks in Dutch :-)

All the pin settings look correct compared to a working espHome build

# Setup SPI for the display. The ESP32-2432S028R uses separate SPI buses for display and touch

[rzeldent]

The last warning is nothing important; that's LVGL.

The settings seem to match indeed. Have you tried the normal esp32-2432S028?
The board is really a esp32-2432S028?

[Grey-Lancaster]

Yes I have tried both. I am not sure what I did the other day to make it work. There are 2 different ..R.json files around. One is 77 lines the other like 114. I "think" the other day the clone had the small file and I replaced it with the big file and it worked. (I could see Lena). Now the clone has the big file and if I replace it with the small file, it will not build.

I have a "normal" non usb-c board due in, in a couple of days. Will see what it does.

[Grey-Lancaster]

@rzeldent Someone somwhere said his board did not have the external memory chip. esphome says my board does not have psram. Does that matter? That said it did work the other day. Lena was just not her beautiful self.

[rzeldent]

This does not matter. Only relevant if you have a parallel connection without controller.

@rzeldent
I have been messing with arduini lvgl code today and got this to work
https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display/tree/main/Examples/LVGL

The only thing interesting possibly is the vendor startup code which is in a diff format but I tried to compare it to yours and nothing stood out to me.

I got a normal CYD today and the demo works fine with 028R
Lena is still big but she looks better than what I somehow had before on the v2
CPU goes up when I tap add, but I cannot see it.
Radio still talks in Dutch :-)

[rzeldent]

See: rzeldent/esp32-smartdisplay#92 (comment)

[Grey-Lancaster]

Thanks, have not tried it yet

[Grey-Lancaster]

@rzeldent
Dev branch said no board but I added one. Anyway it works. CPU is higher that the others and the layout is diff.
But, job well done!
