GUI-Library for microcontroller

c user-interface frameworks embedded atmel

I want to create a GUI driven application for a micro-controller (Atmel XMEGA) that is connected to a 128x64 dots graphics LCD (EA DOGL128-6) and 4 buttons for navigation.

Controlling the display itself (e.g. drawing pixels and characters) is no problem but in order to prevent me from reinventing the wheel I was googling for a GUI-Library/-Toolkit that is written in c, includes its source code, will run on a 32 MHz 8-bit micro-controller and provides at least the following controls:

  • panel (to group elements)
  • menu (scrollable)
  • icon
  • label
  • button
  • line-graph (optional)

But I didn't find any thing useful. Does anyone know (or better uses) such a library(preferably for free)?

I would consider rolling your own "immediate mode" GUI. Jari Komppa has a good tutorial about them. It's a lot easier than you may think, and you'll probably find most GUI libraries--even those targeting embedded systems--are a bit heavy-weight for your system.

If you insist on using a third-party library, below are a few I found. I've never used any of them and they are probably fairly expensive.
