RequirementsΒΆ
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
inlv_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:
Note
Memory usage may vary depending on architecture, compiler and build options.
