Qt Quick Ultralite Platform Porting Guide

Qt for MCUs supports some of the popular microcontroller platforms out-of-the-box. Although this is sufficient in a lot of cases, there is a growing demand to support other hardware platforms.

For this reason, Qt Quick Ultralite offers a set of platform abstraction APIs. These APIs enable third parties to easily port Qt Quick Ultralite to their hardware platforms, and help them achieve faster time-to-market.

This porting guide provides step by step instruction guiding you through the process of porting Qt Quick Ultralite to a new hardware platform.
