STM32中F4系列单片机与启动文件对应关系

前言

在初入stm32学习时，第一步就是创建工程，需要的就是各种不同的启动文件，那f4系列的芯片这么多，如何去选择一款对应的启动文件呢，基于加深自己的记忆，写下了这篇文章

标准库

stm32官方提供f4开发的标准库，本文以v1.8.0为例
在STM32F4xx_DSP_StdPeriph_Lib_V1.8.0\Libraries\CMSIS\Device\ST\STM32F4xx\Source\Templates\arm
此文件下提供了所有的启动文件为.s格式（汇编语言）

启动文件内容简介

• 开辟堆栈空间
• 中断向量表初始化
• 复位程序
• 中断服务程序
• 初始化堆栈

启动文件

芯片对应

• 本次学习使用的是STM32f401RET6芯片
• 在stm32f4xx.h文件中寻找该对应芯片的启动文件

宏定义

• #define STM32F40_41xxx
• #define STM32F427_437xx
• #define STM32F429_439xx
• #define STM32F401xx
• #define STM32F410xx
• #define STM32F411xE
• #define STM32F412xG
• #define STM32F413_423xx
• #define STM32F446xx
• #define STM32F469_479xx

使用

加入启动文件后我们要在keil软件中使用这些宏
点开options按钮到c/c++界面，在define中添加STM32F401xx,USE_STDPERIPH_DRIVER
前面的替换为自己所使用芯片的宏名，后面的代表可以使用官方的标准库外设文件，中间用逗号隔开，注意不要用中文逗号

结束

这就是关于启动文件的内容了，接下来就是添加一些内核文件，外设库文件等等，就建立好一个新工程了

自知水平不足，有错误的地方请各位大佬指正。
