Comparison of Qt for MCUs and LVGL Frameworks

This technical report presents a comparison between Qt for MCUs and LVGL frameworks based on two independent studies. It outlines various scenarios where Qt for MCUs may be preferred over LVGL, particularly when optimizing time-to-market is critical. The report details how Qt for MCUs can reduce development time by 30% and provides advantages in terms of higher frames per second (FPS), better render times, and lower CPU consumption. Additionally, it discusses the ease of scaling Qt across multiple device classes and the ability to reuse code when transitioning between microcontroller units (MCUs) and microprocessor units (MPUs). The report also addresses factors such as safety, support, and certification, highlighting that Qt for MCUs is committed to CRA standards and offers long-term support. A comparison of performance metrics between the two frameworks is included, showcasing differences in development time, FPS, and CPU usage.
