摘要
介绍了一种基于RT-Thread和STM32的数码相框的设计。本系统采用STM32为控制核心,RT-Thread作为嵌入式操作系统,通过μC/GUI绘制人机交互界面,并在μC/GUI中添加了中文汉字显示功能,利用SPI FLASH存放图片、字库文件,移植了文件系统FATFS用于读取文件信息,利用图片解码算法处理相关格式图片,通过触摸液晶屏实现对图片的浏览操作。本系统可实现JPEG格式图片的浏览,具有操作简单,便于携带,显示流畅等优点。
This paper introduces a kind of digital photo frame which is based on the RT-Thread and STM32.The system uses the μC/GUI to draw user interface and can display Chinese characters, it can store pictures or font library files in SPI FI.ASH and read information through the FATFS, the system uses image decoding to process the pictures, it can realize the function of browsing pictures by die much LCD.The test shows that the digital photo frame features with easy to operate and maintain, convenient to take and smooth display.
