LVGL for frame buffer device

Example project to use LVGL with a Linux frame buffer device, for example /dev/fb0.

Check out this blog post for a step by step tutorial: https://blog.lvgl.io/2018-01-03/linux_fb

Clone the project

Clone the LVGL Framebuffer Demo project and its related sub modules.

git clone https://github.com/lvgl/lv_port_linux_frame_buffer.git
cd lv_port_linux_frame_buffer/
git submodule update --init --recursive

Build the project

mkdir build
cd build 
cmake ..
make -j

Run the demo application

As root

Normal users don't have access to /dev/fb0 so use sudo (or see below) :

cd ../bin
sudo main

Userland

You can give a normal user access to the framebuffer by adding them to the video group :

sudo adduser $USER video
newgrp video
cd ../bin
./main

Notes

• The Makefile is broken right now, so Cmake shall be used.
