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: ```auto /* * 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 … ```auto [spoiler] c:/users/roland/.platformio/packages/toolchain-xtensa@2.40802.200502/bin/../lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld.exe: .pio\build\d1_mini\libd96\libESPAsyncTCP.a(ESPAsyncTCP.cpp.o): in function `AsyncClient::_s_error(void*, long)': ESPAsyncTCP.cpp:(.text._ZN11AsyncClient8_s_errorEPvl+0xc): multiple definition of `AsyncClient::_s_error(void*, long)';

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`: ```auto -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
