北京网站建设过程,湖南住建云网站,学校网站功能描述,1核1g可以做几个网站1、标准外设库获取第一步，首先获取标准外设库，可以从官网进行下载。 https://www.st.com.cn/zh/embedded-software/stm32-standard-peripheral-libraries.html 根据自己的型号选择不同的系列，我这里选择是STM32F1系列下载最新版本V3.6&a…

1、标准外设库获取

第一步，首先获取标准外设库，可以从官网进行下载。

https://www.st.com.cn/zh/embedded-software/stm32-standard-peripheral-libraries.html

根据自己的型号选择不同的系列，我这里选择是STM32F1系列

下载最新版本V3.6，点击获取版本后，需要进行登录账号，没有账号的话，可以填写邮箱，ST官方会通过邮件的方式自动发送下载链接，一般点击之后几分钟之内就会收到邮件，邮件里面点击链接进行获取软件。

2、标准库模板搭建

在标准库模块搭建之前，需要做好下面工作，keill安装不做过多介绍，pack包可以在keill在线安装，也可以通过官网下载安装，标准库第一步已经完成。

已经安装好 Keil 软件
已经安装好 STM32F1xx 的 Pack 包
已经下载好 STM32F1xx 标准固件库

2.1、工程文件目录创建

Project:放工程文件，编译文件等。
Firmware：放 ARM 内核文件，标准外设库文件等。
Hardware：放开发板的硬件驱动文件。
User：放 main 函数，stm32f4xx_it 文件，systick 文件。
Doc: 放 readme.txt 文件，工程说明文件。

2.2、固件库移植

下载官方标准固件库之后，得到是是一个zip压缩文件，将文件解压。

然后将en.stsw-stm32054_v3-6-0\STM32F10x_StdPeriph_Lib_V3.6.0\Libraries 文件夹下的内容全部拷贝到新建目录的Firmware 下

2.3、程序入口移植

找到我们的固件库的下载目录，将en.stsw-stm32054_v3-6-0\STM32F10x_StdPeriph_Lib_V3.6.0\Project\STM32F10x_StdPeriph_Template中的如下文件进行拷贝

将这些文件全部都拷贝到我们的新建目录User文件下

2.4、Keil工程相关配置

打开 keil，点击最上面的 Project 选项卡，选择 New uVision Project 选项新建一个工程

选择保存路径为我们刚才创建的文件夹下的 Project，文件名为 STM32Template，然后点击保存

现在我们工程创建好了，下一步选择对应芯片型号

确定所需芯片之后，弹出 RTE 的环境配置对话框，选择工程所需的组件，不用配置,点击取消

下一步分组创建，将相应文件添加到分组中

创建完分组左边项目览如下图所示，Firmare中存放着我们的标准外设文件。根据需要进行添加，

需要注意，不同103的启动文件不一样，根据自己的型号进行选择，我这边是STMF103C6T6,32k内存，属于小容量芯片，选择startup_stm32f10x_ld.s

如何选择可以看这下面两个图片，了解自己的芯片内存大小选择合适的启定文件导入。

导入之后下一步进入工程配置

点击魔法棒，进入配置，在Target中选择V6.21。

output中勾选Browse infomation，勾选之后编译的时候自动生成hex文件。

在C/C++中按照如下图进行配置，include Path为文件路径，根据自己分组进行添加。

在Debug选择自己的烧录方式

2.5、增加延时函数

在User中增加systick.h和systick.c

/*!\file    systick.h\brief   the header file of systick\version 2016-08-15, V1.0.0, firmware for GD32F4xx\version 2018-12-12, V2.0.0, firmware for GD32F4xx\version 2020-09-30, V2.1.0, firmware for GD32F4xx\version 2022-03-09, V3.0.0, firmware for GD32F4xx

}/*!\brief    delay decrement\param[in]  none\param[out] none\retval     none

void delay_decrement(void)
{if(0U != delay) {delay--;}
}

打开"stm32f10x_it.c"拉到最后，然后删除

2.6、程序代码修改

打开 main.c 文件，删除一些不必要的代码，加上系统时钟，剩余部分如下：

#include "stm32f10x.h"
#include <stdio.h>
#include "systick.h"int main(void)
{
//系统滴答时钟初始化
systick_config();while (1){}
}

在stm32f10x_it.h中添加头文件systick.h

3、测试程序

点亮PC13,每秒进行亮灭闪烁。

#include "stm32f10x.h"
#include <stdio.h>
#include "systick.h"//PC13 GPIO初始化void gpio_config() {//开启时钟RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC,ENABLE); //开启GPIOC的时钟//使用各个外设前必须开启时钟，否则对外设的操作无效/*GPIO初始化*///定义结构体变量GPIO_InitTypeDef 	GPIO_InitStruct;//GPIO引脚，赋值为第13号引脚GPIO_InitStruct.GPIO_Pin  = GPIO_Pin_13;//GPIO速度，赋值为50MHzGPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;//GPIO模式，赋值为推挽输出模式GPIO_InitStruct.GPIO_Mode = GPIO_Mode_Out_PP;//将赋值后的构体变量传递给GPIO_Init函数GPIO_Init(GPIOC,&GPIO_InitStruct);}int main(void)
{//系统滴答时钟初始化systick_config();//GPIO初始化gpio_config();while (1){//引脚设置为低电平GPIO_ResetBits(GPIOC,GPIO_Pin_13);//延时1000msdelay_1ms(1000);//引脚设置为高电平GPIO_SetBits(GPIOC,GPIO_Pin_13);//延时1000msdelay_1ms(1000);}
}

4、问题与解决

1、STM32报错Error: L6218E: Undefined symbol assert_param

.\Objects\STMF103FC6T6.axf: Error: L6218E: Undefined symbol assert_param (referred from stm32f10x_gpio.o).

在C\C++设置一栏中输入USE_STDPERIPH_DRIVER使宏生效即可解决问题

2、../User/stm32f10x_it.c(136): error: call to undeclared function 'delay_decreme'

delay_decreme未定义，需要在stm32f10x_it.h中添加头文件systick.h

../User/stm32f10x_it.c(136): error: call to undeclared function 'delay_decrement'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]136 |         delay_decrement();
