### What do you want to achieve?

I have an existing ESP32 project on a ESP32-2432S028R display board using LVGL 9.2 where I manually created several tabs and functions to control a machine. It works but I would like to use Squarline Studio (SLS) to build much nicer UI.

### What have you tried so far?

Researched for many hours, many articles, many YouTube videos.  
I have done the following:

- created a simple test project in SLS using the Bouncing Ball example,
- exported it to a folder as well as exporting the UI files.
- opened Arduino IDE 2.3, set the sketchbook location to where I found the .ino file.
- installed the needed libraries
- moved the lv\_conf.h file as needed
- updated the User\_Setup.h file to settings I know work on my existing project
- tried using a board I downloaded called 2432S028R as well as using the standard  
When I compile the ui.ino file I get an error “Compilation error: ui.h: No such file or directory”.

Can anyone point me to current “How-To” to do this? It seems like all help I find is out of date and doesn’t work.

Hello @Bruster999,

I took a quick look at nishad2m8’s board file on his GitHub page, and it seems that this board is still a work in progress (WIP). That might be the reason you’re experiencing issues.

 ![{21689368-14DB-400C-8429-DE88FC95DF89}](http://forum.squareline.io/uploads/default/original/2X/0/040e847db5f0500732cb4a8903681f25fccac824.png)

Have you tried using the original board that is available for download in the Studio?  
Additionally, when you export the project in Studio there is a README.md file that contains the necessary setup steps for getting started. Please check that and see if it helps.

I’m using the same board and would like to generate lvgl-micropython code. Is there documentation of how to go about adding a board to SquareLine?

Hi, unfortunately, we don’t have a tutorial yet for using the exported LVGL MicroPython code or adding a custom board to SquareLine Studio. However, we are planning to publish documentation for this in the near future.

Thank you for your patience!
