Edit on GitHub

Basically, every modern controller which is able to drive a display is suitable to run LVGL. The minimal requirements are:

  • 16, 32 or 64 bit microcontroller or processor

  • 16 MHz clock speed is recommended

  • Flash/ROM: > 64 kB for the very essential components (> 180 kB is recommended)

  • RAM:

    • Static RAM usage: ~2 kB depending on the used features and Widget types
    • stack: > 2kB (> 8 kB recommended)
    • Dynamic data (heap): > 2 KB (> 48 kB is recommended if using many GUI Widgets). Set by LV_MEM_SIZE in lv_conf.h.
    • Display buffer: > "Horizontal resolution" pixels (> 10 X "Horizontal resolution" is recommended)
    • One frame buffer in the MCU or in an external display controller

  • C99 or newer compiler

  • Basic C (or C++) knowledge:

Memory usage may vary depending on architecture, compiler and build options.
