将图片二进制数据存到外部存储器里,然后读取外部存储器即可读取图片数据。 增加了外部FLASH来存图片数据并在显示屏显示出来,图片显示速度快,弥补了主控芯片内存不足的问题,但是采用最原始、最简单的将图片数据写入W25Q64的方法 在嵌入式系统开发中,STM32F103RCT6微控制器凭借其高性能和丰富的外设资源,成为广泛使用的32位MCU之一。配合使用0.99寸的TFT圆屏显示器,能够开发出多种交互式应用界面。在处理图形显示时,STM32F103RCT6的内置存储器往往容量有限,这就限制了可以存储和显示的图像数据大小。为了解决这一问题,开发者们采取了使用外部存储器扩展的方法。其中,W25Q64作为一款高速、大容量的串行外设接口(SPI)闪存,被广泛应用于扩展STM32F103RCT6的存储能力。 在本项目中,利用硬件SPI和DMA(直接内存访问)技术,可以高效地从外部的W25Q64 FLASH中读取图片数据。这种方法不仅提高了数据传输的速度,还减轻了MCU的负担,使得主控制器能够更加专注于处理其他任务。通过这种方式,可以在显示屏上快速显示存储在外部FLASH中的图片,有效地解决了主控芯片内存不足的限制。 此外,本项目的高级实现还包括了使用外部FLASH来存储图片数据的步骤。这一过程中,需要将图片转换为二进制格式,然后将其写入到W25Q64 FLASH中。由于W25Q64 FLASH是基于SPI接口的,因此在写入过程中,可以通过SPI总线直接与STM32F103RCT6进行通信,无需中间的转换接口,这样可以进一步提高数据传输效率。 对于图像显示这一块,项目采用了特定的显示驱动程序和相应的算法,这些驱动程序和算法专门针对0.99寸TFT圆屏显示器进行了优化,以确保图像显示质量。同时,利用DMA进行图像数据的读取可以减少CPU的参与,从而减少了对CPU资源的占用,提高了程序的运行效率和响应速度。 通过本项目的实施,不仅可以扩展STM32F103RCT6的存储能力,还能提升其图形显示的性能。这样的系统设计为嵌入式应用提供了更多的可能性,尤其是在那些需要处理大量数据或需要高质量显示的应用场景中,具有重要的实践价值和应用前景。
