摘　　要：STM32F4x9系列微控制器内置Chrom-Art图形加速器,能够快速地对位图数据进行复制、格式转换、颜色混合等操作。为了在STM32上实现更好的人机交互体验,针对该功能,提出一种基于智能区域的嵌入式GUI架构,并使用ANSI C语言设计实现,通过该架构可以方便地设计出美观而生动的人机操作界面。实验证明,该图形架构具有轻便、高效、灵活等优点,具有一定的实际应用价值。The STM32F4x9 series microcontroller embedded with Chrom-Art accelerator can offer the following operations on the bitmap data such as copy, pixel format conversion and color blending. In order to achieve a better human-computer interactive experience on the STM32,an embedded GUI framework based on intelligent area is proposed, which is implemented by using ANSI C. User interface with outstanding graphics and smooth animations can be easily designed through this framework. The experiment results show that this graphic framework is lightweight, efficiency and flexibility, and has some practical value.
