本文详细解析了使用keil5环境开发STM32过程中遇到的IRQn_Type error问题，并提供了两种解决方案：一是更换为高密度STM32芯片；二是选用与设备相匹配的启动文件。通过正确配置，最终实现编译无错误、无警告的目标。

用keil5环境开发STM32和keil4开发stc的C51完全不同，记下一个坑

 

这个IRQn_Type  error原因其实很简单，就是选择的启动文件（startup）startuo_stm32f10x_hd.s是用于高密度的，而调试的device我选择的是STM32F103C4，不匹配。

解决办法:

1)改device，选择高密度的芯片，如STM32F103VE

2)更改启动（startup）文件，选择匹配的启动文件，如startup_stm32f10x_ld.s

 

最后显示no error,no warning 表明编译成功

STM32（HAL库）中设置中断优先级函数__NVIC_SetPriority(IRQn_Type IRQn, uint32_t priority)详解

在第一部分代码中有一个强制转换（uint32_t)IRQn，因为中断号为负数，在计算机中负数用补码存储，以-5为例，8位二进制表示为1000 0101 ，反码为1111 1010 ，补码为1111 1011，将其转为无符号32位其为11111111 11111111 11111111 11111011；该处8代表了 SCB->SHP[8]中此处的数组中的元素，表明SHP中的第9个元素为SVCall的优先级。上述代码为系统硬件的IRQn，可以发现均小于0，
STM32 #20: identifier “XX_IRQn“ is undefined

问题描述： 标题也描述了报错了 在进行中断使能的时候出现了这个问题 原因分析： （1）报错可见是未定义，那么肯定是没有包含啥头文件，但是去看头文件却发现其实是已经包含了的，所以继续看下去 （2）把对于的这个符号改为数字10，仍旧报错 那么我们先进去函数看下 （3）函数如下，需要传入一个中断类型的参数 （4）查看这个中断类型定义 （5）往上查看我们需要的IRQn 找到了，但是要注意其是在下图条件下的 也就是必须宏明是stm32f40_41xxx，才能使用，所以改下既可以 #if defined (

今天在用keil5编译的时候出现了这个错： …\CORE\core_cm3.h(1569): error: #20: identifier “IRQn_Type” is undefined； 点到后，直接链接到core_cm3.h中的。网上搜索后，都是说因为没有加#include “stm3210x.h”，然后我就把#include "stm3210x.h"加到了core_cm3.h中。结果依然没有变化。最后我将#include "stm3210x.h"加到我正在写的flash.h的头文件中，这个错误就.

选择魔法棒，将默认编译器改为版本5的。若修改完之后，重新编译还是报错，可以考虑重新安装版本5的编译器。Keil5默认使用的是版本6的编译器，但固件库支持的是版本5的编译器。根据江协科技视频教程编写代码后，出现如下错误。

core_cm3.h文件中使用了IRQn_Type类型名，但是此类型名是在中定义的，所以需要在头部加上但是中的IO 定义(__I, __O, __IO)又在core_cm3.h中, 所以还会报错, 再加一步把core_cm3.h中的IO definitions迁移到, 问题算是暂时解决了.

STM32的中断操作（一)——EXTI
weixin_43790761的博客

在单片机的编程中，中断都是很重要的一个概念。在stm32中，中断有两种，一种是外部中断（EXTI），另一种是定时器中断（SysTick），本篇文章从中断的概念入手，再对外部中断简要的做一些介绍。相信大家在初学中断这个概念时都听过这样一个例子：如果你一个人在家里正在做饭，这时门铃响了，你选择先去开门，然后再回来做饭，这就是一个浅显易懂的中断的例子，做饭为主程序，而去开门就是中断程序，门铃响起就是中断请求。而如果门铃响起同时电话也响起，那么你决定先去处理哪一件事的过程就是中断优先级的判别过程。 中断的定义如下：
