<p cid="n25" mdtype="paragraph"><a href="http://embeddedlightning.com/ugui/" spellcheck="false">μGUI - free Open Source GUI module for embedded systems | Embedded Lightning</a></p>
<blockquote cid="n50" mdtype="blockquote">
<p cid="n45" mdtype="paragraph">µGUI is a free and open source graphic library for embedded systems. It is platform-independent and can be easily ported to almost any microcontroller system. As long as the display is capable of showing graphics, µGUI is not restricted to a certain display technology. Therefore, display technologies such as LCD, TFT, E-Paper, LED or OLED are supported. The whole module consists of two files: <strong>ugui.c</strong> and <strong>ugui.h</strong>.</p>
