1. Project Overview
This is an open source project that binds the LVGL embedded GUI library to MicroPython , a derivative version of lv_micropython and lv_binding_micropython . Its core goal is to enable developers to use the Python language to develop graphical interfaces on microcontrollers, while simplifying the compilation process, unifying APIs, and expanding hardware support.
•
Binding (Binding) can be understood as a "language translator": LVGL is an embedded GUI framework written in C language, and this project encapsulates the C language LVGL API into a Python callable interface through "glue code", allowing MicroPython developers to directly operate all functions of LVGL using Python without writing low-level C code.
•
MicroPython: A lightweight version of the Python language, designed specifically for resource-constrained microcontrollers (MCUs), with extremely low memory footprint while retaining Python's concise and user-friendly syntax and hardware access capabilities.
•
LVGL: is one of the most popular open-source GUI frameworks in the embedded field, implemented in C99, optimized for low-resource devices, providing rich UI components such as buttons, labels, lists, animations, etc., and supporting touch interaction and complex interface layouts.
The project's objectives are as follows:
•
Simplify the compilation process of LVGL + MicroPython and lower the entry barrier.
•
Unify API specifications to facilitate developers in adding new display/input device drivers.
•
Supports more hardware connection topologies and adapts to different embedded product forms.
•
Optimized Performance: Underlying optimizations have been made for scenarios such as RGB buses, improving GUI rendering frame rates while reducing memory usage.
1.1 Key Architectures and Features
The project has refactored the dependency logic: Instead of being a subsidiary component of MicroPython, it now makes MicroPython a dependency of this project . This change has greatly simplified the adaptation work for MicroPython version upgrades, requiring only minor modifications to support the new version of MicroPython and avoiding the hassle of frequent refactoring of binding code in the past.
The project provides make.py Python script to handle compilation uniformly, supporting mainstream embedded platforms:
•
Target platforms: ESP32, STM32, RP2 (Raspberry Pi Pico), Renesas RA, nRF, i.MX RT, SAMD, etc., while also supporting Unix/macOS desktop simulation (for easy debugging).
•
Build dependencies: Requires Python ≥ 3.10 and a C compiler (gcc/clang/msvc), and different platforms need to install the corresponding toolchain (e.g., ESP32 requires build-essential , cmake , etc.).
•
Note: Windows platform is not yet supported, and macOS/Unix versions need to be compiled locally and then run directly.
1.2 Support and Features
Supports most mainstream LCD driver chips and, including mainstream capacitive/resistive touch chips:
