Help Setting Up Rotary Display

Other Hardware Displays
1

Hello,

I am trying to setup a 1.28LVGL rotary screen for a project I'm working on.

I want to connect it to an Arduino Uno/mega but I'm confused on where to make my connections since there are 2 rows of pins.

Does anyone have an idea on how to go about this, so I can start messing around with it?

Thanks in advance.

Project Context:
I'm using it as a digital eye for my Destiny Ghost model. So I don't really need the rotary/button function (it's just an added bonus), just need it do display a blue moving circle:

Give yourself an early Christmas present and pick up these resources, along with the Arduino Cookbook:

Does anyone know if this can work off an Arduino UNO/mega. When I read the docs it's all based off an ESP32. I'm wondering if this will work with off an UNO/Mega. Will the connections still be the same (5v-5v,gnd-gnd,rx-tx,tx-rx. Do I use the UART side or the other side? Which one's better?) and how does it get programmed?
Has anyone played around with this model or similar and got it working? Just curious.
Thanks.

Hi, @ClassifiedSecret
This link should help.

The control PCB already has an ESP32 on board.
If you plug the PC into the USB socket on the PCB it should connect.

Sorry I'm not familiar with this product, only what I have Googled.

Thanks for the help. I followed the documentation they have, but I keep getting a compiling error.

Alternatives for process.h: []C:\Users\PC\Documents\Arduino\libraries\lvgl\src\osal\lv_windows.c:14:10: fatal error: process.h: No such file or directory

   14 | #include <process.h>ResolveLibrary(process.h)

      |          ^~~~~~~~~~~  -> candidates: []

compilation terminated.


exit status 1
Error compiling for board ESP32S3 Dev Module.

What does this mean & how do I fix it?

I'm using the lv_windows.c from the docs

this is a snippet:

/*********************
 *      INCLUDES
 *********************/

#include "lv_os.h"

#if LV_USE_OS == LV_OS_WINDOWS

#include <process.h>

/*********************

Fixed it. Just uninstalled/reinstalled everything, and talked to customer support.
