Description
What MCU/Processor/Board and compiler are you using?
ESP32s3 Dev Module
What LVGL version are you using?
8.3.3
What do you want to achieve?
Add custom heart icon to button (Only “[]” is displayed)
What have you tried so far?
Add custom font including icon with Online font converter.
Add icon to lv_symbol_def.h
Move font into lvgl/src/font
Code to reproduce
Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.
The code block(s) should be formatted like:
workingScreen.ino
