Thanks with this firmware i get the Usermod finally shown!
But after disconnec the Wemos from the PC and then connect it to the PSu the litle Blue LED is flashing and the AP does not open anymore.
Edit: It also happens afer safeing settings.But when using the “normal” without ay usermod it works.
Edit 2: just in case someone has the same issue. There was a problem with GPIO4 and the Mod. All new bin files should have a fix in it 
For no particular reason I decided to play with WLED with an OLED display. I flashed your esp32_display.bin to a ESP32 DevkitC V4 with no problems. Worked flawlessly. Thanks for your work!!
Now I would like to play around a little more and start learning more with PlatformIO and Usermods. Do you have the source files available?
Thanks in anticipation from appreciative old fella!
Everything is on Github.
Clone @Aircoookie repository or mine (for more experimental features).
Thank you for the reply. I was specifically asking @srg74 if the source files were available for the esp32_display.bin that he had posted earlier in this thread.
And I have answered you.
Yes , the source files are in my or Aircookies repository on Github.
@srg74 uses those to provide binaries.
Sometimes your curt and abrupt replies are not very helpful to someone trying to learn. You come across as very rude and arrogant!
I am neither of those. It is how you choose to interpret.
Anyway, all of the sources are on Github and we do not hide anything. Any feature we come up with is shared for free with anyone.
Maybe I am interpreting wrong.
The sources on Github do not help me understand which Usermod was used and how it was used to generate the bin file I flashed.
A little bit more explanation would go a long way to help me.
For understanding how they configured read this file WLED/platformio_override.ini at WLED_wemos_shield · srg74/WLED · GitHub
Sorry for the bluntness but a little bit of elbow grease does wonders. Most often than not.
By elbow grease I am referring to opening a decent editor (Visual Studio Code is a prime example, but you may choose another) and peeking into the code itself. It does take time but gives you all the insights needed. There are of course plenty of YT channels explaining the basics of compiling (and modifying) WLED from source too.
If you are referring to display binary there are several display usermods included with WLED, but @srg74 is building his binaries with the “4 Line Display” usermod in particular. This usermod was originally written by Kevin Dorff, but subsequently heavily modified by me.
All usermods are stored in usermods folder and some of them require only #define ... or -D USERMOD_... at the compile time to be automatically included. This is the case with “4 Line Display” usermod.
& @srg74 Thank you!
This is the kind of help I was looking for to point me in the right direction. This is the first time for me to have a go at using PlatformIO and was a little daunting for my 70 year old brain. I don’t mind putting in the work but it is nice to know that I am on the right road. Thanks to both of you for this assistance.
Take heart, there’s a few (at least) of the over 58 crowd out here.
Some of us started in computing before the original IBM PC, back when processor speeds were a heady 1Mhz 
@blazoncek and @srg74 are well known in this forum and justly so, they’ve added huge amounts to @Aircoookie’s amazing project.
That said I sympathize with your blank stares when first looking at this code, coding styles and best practices have changed over the last 45 years…
All I can suggest is try and start small and build up as you can.
Many times I find myself going back to the “Blink LED” project and adding in some small piece of code I’m trying to understand.
Sometimes you have to build the tools to build the tools to build the tools you need to get something done.
