Cannot compile WLED with USERMOD_ROTARY_ENCODER_UI and USERMOD_FOUR_LINE_DISPLAY

Usermods
1

Hi there,
I try to include an OLED Display together with a rotary encoder.
I’m using VS Code. Initial cloning from github , compiling und uploading without changes to a Wemos D1 Mini was working fine.
No I want let the next D1 working with a display and rotary encoder.
What I did:

  • copy platformio_override.ini.sample from …\usermods\usermod_v2_rotary_encoder_ui to the folder in WLED Project where platformio.ini is located
  • rename file to platformio_override.ini
  • add definitions to usermod_list.cpp:
/*
 * Register your v2 usermods here!
 *   (for v1 usermods using just usermod.cpp, you can ignore this file)
 */
#define USERMOD_ROTARY_ENCODER_UI
#define USERMOD_FOUR_LINE_DISPLAY
#define ENCODER_DT_PIN 12
#define ENCODER_CLK_PIN 14
#define ENCODER_SW_PIN 13
#define FLD_PIN_SCL 5
#define FLD_PIN_SDA 4
/*
 * Add/uncomment your usermod filename here (and once more below)
 * || || ||
 * \/ \/ \/
 */
//#include "../usermods/EXAMPLE_v2/usermod_v2_example.h"

I tried to compile several times with no success at all. There are a lot of warnings regarding libs:
(I did not shorten it, I don’t know, what is important to solve the problem)
I have seen, that WLED without these usermods uses newer versions of some libs. Can it be that the lib dependencies from platformio_override.ini are not working with current WLED version? Or am I wrong? Perhaps is there more ToDo?

Thanks a lot
Roland

… sorry for asking in github before …

Undo changes to source code, copy platformio_override.ini.sample into platformio_override.ini, create environment for your set-up and add this to your build_flags:

-D USERMOD_FOUR_LINE_DISPLAY
-D USERMOD_ROTARY_ENCODER_UI
-D USE_ALT_DISPlAY

There is no need to define pins as those can be adjusted during runtime.

Thanks for helping.
I changed build_flags in platformio_override.ini as recommended and defined only
#define USERMOD_ROTARY_ENCODER_UI
#define USERMOD_FOUR_LINE_DISPLAY
in usermods_list.cpp.
But, however, still tons of warnings from linker regarding ESPAsyncxxx libs.
What I have done in addition:
I changed sector [env] lib_deps in platformio_override.ini:
from fastled/FastLed @ 3.2.2 to version 3.5.0 as in platformio.ini
ESPAsncTCP @ 1.2.0 to version 1.2.2 (also just like platformio.ini)

Now compiling runs successfully.
So, my idea about the wrong lib dependencies defined in this usermod was correct.
Now I’m happy
And last but not least: Thanks a lot for this great piece of Software called WLED. Currently I have 3 WLED controllers and I use them with a lot of fun!

Kind regards
Roland
