Hi all, I would like to use an usermod (I2C 4 Line Display Usermod) that is already in the github wled usermod area. I’m very new to this and I would like to know if I’m understand correctly:

For the v2 usermod I need to compile wled or I just need to download wled binary and than copy the usermod.h to wled00 (just drag the file?)

After, how i have to register the usermods in usermods\_list.cpp?

(All the usermods that is in the github area of wled are already registeted?)  
How I can tweak the option of this usermod, like choose the correct display?  
Thank you all for the support

Use flags instead of alternating code:

```auto
  -D USERMOD_FOUR_LINE_DISPLAY
  -D USE_ALT_DISPlAY

```

Check @Quindor videos.

thank you, so I figured out how to, but know I got this error when I’m try to connect to the wemos d1 mini,

**SyntaxError: Unexpected token ‘\<’,"**

the display works and shows all the info but the GUI shows the error above  
this is the platformio\_override that i’v made

there’s a strange problem with different compile metod:  
If I download the source code from github, i got this error

 ![1](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/0/0c48d6c268d855290b1ee43976bfd404b91ec370.jpeg)

If I try to compile with the metod of kno.wled.ge where you need to download wledmaster I have the problem that visual studio doesn’t create the bin, but when I try to upload directly from visual studio code to wemos, i got the gui syntax error and wled not work.

I don’t know what to do, and what is the correct way… I search on the internet and see the intermittech video but no one follow the same step of the wled site…

You are not using the latest source.  
And as can be seen from 1st screenshot, you successfully flashed ESP.

Thank you! You talk about the u8g2 library?

I change the u8g2 library to the latest and got always the same error, **SyntaxError: Unexpected token ‘\<’,"** even if I don’t use override and try to only compile

“Syntax error” is a bug in current WLED when accessing controls fro AP mode.  
Connect to WiFi and it should work or wait for an update.
