ESP32 maximum resolution?

[radontec]

Hello all,

I have a question of interest regarding displays and the ESP32.
The largest screens used on an ESP32 are 3.5inch with 480x320
I have not seen one with a higher resolution, do you know why? Or is there some kind of limit from the processor power or number of GPIOs which doesn't allow a higher resolution?

The software potentially allows 32000 x 32000 pixels!

The largest display I have used is an SSD1963 based TFT which is 800 x 480.

Hi Bodmer,

Do you know of any SPI display driver ICs that would support a similar resolution, that are supported by the library?

Thanks,
Brother

@Bodmer I don't suppose you recall which parallel interface you used ? 6800 or 8080

EDIT: It looks like the board ships configured but with excellent soldering skills you could change this...

And font chip?

EDIT: I am guessing the font chip is not used. However, researching I'd probably plump for ER3304 with 14 ASCII fonts capability.

8080 is the correct one.
The font chip is not supported by the library, you would need to write functions to read it and render the characters. Just leave that option not selected.
