Hi everyone. Im using ESP32-2432S028 with LVGL and its amazing. Today i tried to use rlottie with LVGL, but its not working. Then i activated it in lv_conf.h file, and finally i imported the rlottie library to my project.
I did it like this:
- Downloaded 0.2 (latest) version of rlottie by Samsung on GitHub
- Renamed the folder (rlottie-0.2 to rlottie)
- Moved that folder to lib folder
And also, my platformio.ini file looks like this now:
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
lib_extra_dirs =
~/Documents/Arduino/libraries
lib/rlottie
lib_deps =
ArduinoJson
(lvgl and other required libraries are in Arduino/libraries)
And my output is:

If you need any more info, i will give it as well 
Thanks!
