What is µGFX?

µGFX is a lightweight embedded library for displays and touchscreens providing everything required to build a fully featured embedded GUI.

The library is very small and fast because every unused feature is disabled and not linked into the finished binary.

A complete solution

The µGFX library has been designed to be the smallest, fastest and most advanced embedded library for display and touchscreen solutions.

  • Small & lightweight
  • Fully customizable and extendable
  • Highly portable
  • Support for all display types: Monochrome over grayscale up to full color displays
  • Support for hardware acceleration
  • Over 50 ready-to-use drivers
  • Written in C, can be used with C++
  • Free for non-commercial uses
  • Fully Transparent: The entire source-code is open
  • Works on low RAM systems. A framebuffer is not required for most displays
  • Fully multi-threading re-entrant. Drawing can occur from any thread, at any time!

The uGFX library runs on virtually any platform

Processor Agnostic

The µGFX library works on any processor architecture. No matter whether it's a small 16-Bit microcontroller or a huge 64-Bit multi-core ARM CPU.

System Agnostic

The µGFX library runs on any system. It can be used with or without underlying operating system.

Highly Portable

No matter what system you've got - µGFX will run on it.
From the smallest, lowest-power microcontroller to the fastest, multi-core systems - µGFX will run on it.

How it works

How can µGFX be completely portable while offering the smallest and fastest embedded graphics solution on the market?

  • Abstraction

    An easy to use, yet highly flexible abstraction layer allows to run the µGFX library on virtually any platform. The abstraction layer has been designed to have as little performance impact as possible.

  • Code exclusion

    Every unused feature is disabled. Disabled features are not getting compiled and don't end up in the finished binary. Therefore, µGFX code is always as small as possible.

  • Hardware acceleration

    Wherever possible we provide hardware acceleration interfaces to get the most out of your hardware.

  • Testing

    We frequently perform rigorous tests where we literally copy-paste code and run it on different platforms to ensure that the library meets our high quality demands.


The µGFX library has a huge list of different features which make it what it is - the best embedded library for display and touschreen purposes.

Resource Friendly

We save every byte of memory and every CPU cycle we can. µGFX is small and fast.

Runs on any display

Monochrome, grayscale, color, resistive, capacitive or no touchscreen at all... µGFX will run on it!

Advanced text rendering

Advanced text rendering features such as anti-aliasing, unicode and kerning support.

Hardware acceleration

Take advantage of hardware acceleration wherever possible.


The entire source code is open and publicly available. We hide nothing from you.


All documentation is available for free. Don't pay for something that should be free!

Memory management

Everything in µGFX can be used with either static or dynamic memory.

Professional support

Free as well as paid support directly from the µGFX developers themselves.

TRUSTED partners

µGFX runs on virtually any hardware, on any system, with any compiler...
