lvgl-micropython

August 12, 2026 · View on GitHub

MicroPython user C module glue for LVGL: Make/CMake usermod entry points, a GC-aware allocator, and an optional frozen manifest.

This repo does not regenerate bindings. It consumes lvgl-bindings (generated/lvgl_micropython.c + the lvgl submodule).

Layout

Path	Role
`micropython.mk` / `micropython.cmake`	Build glue (`USER_C_MODULES`)
`src/lv_mem_core_micropython.c`	GC-aware LVGL allocator
`manifest.py`	Optional frozen Python modules
`docs/`	This documentation
`tools/test_lvgl_unix.py`	Deprecated smoke wrapper → `lvgl-bindings/tools/test_lvgl_smoke.py`

USER_C_MODULES is the workspace parent (directory containing this repo):

cd micropython/ports/unix
make USER_C_MODULES=../../.. FROZEN_MANIFEST=../../../lvgl-micropython/manifest.py

CMake ports (esp32, rp2): point USER_C_MODULES at this repo.

See the cmods workspace for an easier way to build this repo with other user C modules.
