Anybody found a way to get any of those to compile?

[01GOD]

Hi,

Anybody found a way to make any of those demos compile on a JC4827W543C yet? If did, explaining how would be appreciated! (and would be good to have stored here on the repo anyway)

Thanks in advance!

[lsdlsd88]

which demo do not compile ? did you try helloworld ? did you copy the libraries from the libraries folder to your IDE libraries folder ?

can you link a failed compile log ?

[01GOD]

Hi,

Thanks for replying so promptly. All the libraries are installed (lvgl is 8.4.0). Is the lv_config.h from each specific demo supposed to be copied to the main Arduino libs dir? (So that when compiling a different demo, copy and paste that specific demo's lv_conf.h to the main Arduino lib?)

An example compilation error log from the LvglWdigets demo:

Compilation error: 'Arduino_ESP32RGBPanel' does not name a type; did you mean 'Arduino_ESP32S2PAR8Q'?

PS: Note that it's the JC4827W543_C (capacitive touch variant)

Update: Modified some things and copied that demo's specific lv_config.h to the main Arduino lib dir and the compile errors log is:

Reinstalled the libraries and trying again now.

[01GOD]

Found out that the seller had sent the wrong files originally, as they were for another board. So that was part of the issues originally.

A basic print loop did compile and was uploaded to that board, but that is not why I got a touchscreen ESP32 board.

[lsdlsd88]

start from scratch.

close the IDE

empty your %TEMP% folder.

copy the whole libraries folder from this repo to the ide appropriate folder (make sure to delete any previous existing libraries which may conflict)

get this library

https://github.com/mmMicky/TouchLib

download as zip, extract into libraries folder, remove "-main" from folder name..

copy lv_conf from "3_3-3_TFT-LVGL-Widgets\LVGL configuration replacement file" to your libraries folder

(yes use each conf from each demo, in case its different)

open LvglWidgets.ino

select as board ESP32S3 Dev Module

Compile.

please dont paste output here, link from something like pastebin, or upload as text file.

[01GOD]

Saw now. Was about to post that I got it to compile when saw that guide. Thanks for explaining though!

[01GOD]

By the way, the factory recommended lvgl 8.3.0, although I compiled with 8.4.0. The demos are upside down though and the Widgets demo's touch gestures were backwards seemingly.

Had expected the Widgets demo to be the one it shipped with, but it's sadly a lower quality demo.

Happen to know where the original demo it shipped with (a bunch of icons linked to other demos) is in those Arduino demo files?

Thanks in advance and thanks again for explaining.

[lsdlsd88]

not sure which one is the factory demo unfortuntely. maybe the seller might know ?

[01GOD]

I reside in china (not chinese) and that factory is kinda near here. Anyway, talked to the factory and they said that the template it shipped with is from:
guition.com

That is apparently the tool they made for making GUI interfaces for use with those products. Tried flashing it with the template on that page, but that made the screen go black on that board, although thankfully Arduino restored the other demos.

[lsdlsd88]

ah yeah I've seen talks about that development platform they have. might wanna join Brian Lough discord there's a few users talking about these boards

[01GOD]

Thanks! Apparently that platform had a compile error so it uploaded a blank seemingly.

On the bright side, re-flashed the lvgl Widgets demo and now it looks like the standard non-inverted style lvgl demo that ran on those Sunton boards before. So that is a step in the right direction.

I've mainly made native Apple platform iOS/iPadOS/OSX/macOS apps and Unity apps before, but Apple sadly has had an app store monopoly and I want to port an iPad app I made to this platform. Recommend any open source apps with a nice GUI to load on it and modify for learning how to?

General plan was to use Squareline to make the GUI and Arduino to add the functionality. Hope that is a relatively easy workflow.

[lsdlsd88]

not sure about that sorry. good luck with your project

[01GOD]

Thanks again for assisting to get that compiling. Feels like a smaller first step than I had hoped, but it's a step toward that goal of circumventing Apple's illegal app store monopoly.
