Introduction

SGL (Small Graphics Library) is a lightweight and fast graphics library specifically designed to provide beautiful and lightweight GUI (Graphical User Interface) for MCU-level processors. Please refer to the docs directory for documentation.

Quick Start (Based on SDL2 Simulation)

Steps as follows:

1. Ensure make tool is installed
2. Install gcc compiler, (https://github.com/niXman/mingw-builds-binaries/releases/download/13.2.0-rt_v11-rev0/x86_64-13.2.0-release-posix-seh-ucrt-rt_v11-rev0.7z)
3. git clone https://github.com/sgl-org/sgl-port-windows.git
4. cd sgl-port-windows && git submodule init
5. git submodule update --remote
6. cd demo && make -j8
7. make run

Note: Please use git terminal or VSCode's git bash terminal to enter the above commands

1. Install gcc Compiler

Download gcc from this address (https://github.com/niXman/mingw-builds-binaries/releases/download/13.2.0-rt_v11-rev0/x86_64-13.2.0-release-posix-seh-ucrt-rt_v11-rev0.7z) Then extract to any directory and add to environment variables

2. Pull SGL Demo Source Code

git clone https://github.com/sgl-org/sgl-port-windows.git

3. Configure Project

cd sgl-port-windows && git submodule init
git submodule update --remote
cd demo && make -j8

4. Run
