STM32使用HAL库驱动ST7789的相关代码，包含软件和硬件。 可查看原文链接：https://blog.csdn.net/wan1234512/article/details/147461868?spm=1011.2415.3001.5331 在嵌入式开发领域，STM32微控制器因其高性能、低成本和丰富的外设支持而广受欢迎。ST7789是一种常用的TFT LCD驱动IC，能够提供清晰的显示效果，常用于小型显示屏模块。而HAL库是ST官方提供的硬件抽象层库，旨在为开发者提供一个简化的硬件编程接口。将ST7789驱动集成到STM32开发环境中，不仅可以增强显示功能，还可以在多种应用中实现用户交互界面。 为了实现这一目标，通常需要将ST7789的硬件SPI接口或软件SPI接口与STM32微控制器连接。硬件SPI通信速度更快，效率更高，适合于对速度有要求的场合；而软件SPI则不需要额外的SPI外设，占用更多的CPU资源，但可以节省硬件引脚，适合于引脚资源紧张的场合。在使用HAL库驱动ST7789时，开发人员可以通过配置相应的SPI参数，如时钟频率、数据格式等，实现与显示屏的数据通信。 本项目内容包含以下几个部分： 1. keilkilll.bat：这可能是一个批处理文件，用于在Windows环境下清理或重置Keil MDK-ARM集成开发环境的某些配置或缓存。在进行项目构建或调试之前，运行此文件可能是为了确保环境的纯净状态。 2. Project.ioc：这应该是一个由STM32CubeMX生成的项目初始化文件，用于在Keil MDK-ARM中创建一个基于STM32微控制器的项目。通过STM32CubeMX工具，用户可以选择特定的MCU型号，并配置其外设参数，最终导出初始化代码。这极大地简化了项目创建和配置的过程。 3. .mxproject：这是一个基于STM32CubeMX生成的项目配置文件，包含了项目结构和外设配置的信息。这个文件可以用于导入到Keil MDK-ARM项目中，确保项目与CubeMX工具生成的配置保持一致。 4. Doc.txt：这个文档可能包含了项目相关的信息，如硬件连接说明、软件版本要求、使用说明以及可能的已知问题和解决方案。文档是任何项目的重要组成部分，有助于项目维护和交接。 5. Drivers：这个文件夹中包含了STM32微控制器的驱动程序代码，可能包括HAL库文件、中间件、以及针对ST7789显示屏的驱动实现。在嵌入式开发中，驱动层是连接硬件与应用层的关键环节。 6. Core：这个文件夹通常包含项目的核心代码，包括主函数、中断服务函数等，以及对HAL库函数的调用。在这个部分，开发者会编写应用程序逻辑，如初始化外设、处理用户输入和更新显示屏内容。 7. User：这个文件夹包含了用户自定义的代码文件，允许开发者添加特定的应用功能，如图形界面、数据处理算法等。在此文件夹中，用户可以实现特定的业务逻辑，以满足特定项目的需求。 8. MDK-ARM：这是Keil公司推出的针对ARM处理器的集成开发环境，广泛应用于嵌入式系统的开发。它提供了代码编辑、编译、调试等一系列开发功能，支持多种ARM处理器。 本项目是一个完整的STM32开发套件，不仅包含驱动ST7789显示屏的HAL库代码，还包括项目构建所需的各种文件。开发者可以基于此项目快速开始开发，或将其作为参考来学习如何在STM32微控制器上驱动TFT LCD显示屏。
