esp32 GUI library

[YouJungChoi]

Hello.

What I am currently using are esp32-wrover-E and esp32-wrover-kit v3.

Do you know the GUI library suitable for the product I am currently using?

The library I've used is a library called LVGL. However, there is a problem with using this library as a result of using a lot of resources.
In particular, it takes a lot of time when outputting an LCD to an image converted to LVGL online.
If you have used LVGL, is there a way to compress the image?

Thank you.

Hello.

I have a few more questions.
First, is the license free to sell when using µGFX? If there is a charge, how much does it incur?
Secondly, can the LCD size be 320*240 when applying µGFX to esp32?
Also, can I use ILI9341 or ST7789V for the lcd controller?

Thank you.
