1、標(biāo)準(zhǔn)外設(shè)庫(kù)獲取

第一步，首先獲取標(biāo)準(zhǔn)外設(shè)庫(kù)，可以從官網(wǎng)進(jìn)行下載。

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

根據(jù)自己的型號(hào)選擇不同的系列，我這里選擇是STM32F1系列

下載最新版本V3.6，點(diǎn)擊獲取版本后，需要進(jìn)行登錄賬號(hào)，沒(méi)有賬號(hào)的話(huà)，可以填寫(xiě)郵箱，ST官方會(huì)通過(guò)郵件的方式自動(dòng)發(fā)送下載鏈接，一般點(diǎn)擊之后幾分鐘之內(nèi)就會(huì)收到郵件，郵件里面點(diǎn)擊鏈接進(jìn)行獲取軟件。

2、標(biāo)準(zhǔn)庫(kù)模板搭建

在標(biāo)準(zhǔn)庫(kù)模塊搭建之前，需要做好下面工作，keill安裝不做過(guò)多介紹，pack包可以在keill在線(xiàn)安裝，也可以通過(guò)官網(wǎng)下載安裝，標(biāo)準(zhǔn)庫(kù)第一步已經(jīng)完成。

• 已經(jīng)安裝好 Keil 軟件
• 已經(jīng)安裝好 STM32F1xx 的 Pack 包
• 已經(jīng)下載好 STM32F1xx 標(biāo)準(zhǔn)固件庫(kù)

2.1、工程文件目錄創(chuàng)建

• Project:放工程文件，編譯文件等。
• Firmware：放 ARM 內(nèi)核文件，標(biāo)準(zhǔn)外設(shè)庫(kù)文件等。
• Hardware：放開(kāi)發(fā)板的硬件驅(qū)動(dòng)文件。
• User：放 main 函數(shù)，stm32f4xx_it 文件，systick 文件。
• Doc: 放 readme.txt 文件，工程說(shuō)明文件。

2.2、固件庫(kù)移植

下載官方標(biāo)準(zhǔn)固件庫(kù)之后，得到是是一個(gè)zip壓縮文件，將文件解壓。

然后將en.stsw-stm32054_v3-6-0\STM32F10x_StdPeriph_Lib_V3.6.0\Libraries 文件夾下的內(nèi)容全部拷貝到新建目錄的Firmware 下

2.3、程序入口移植

找到我們的固件庫(kù)的下載目錄，將en.stsw-stm32054_v3-6-0\STM32F10x_StdPeriph_Lib_V3.6.0\Project\STM32F10x_StdPeriph_Template中的如下文件進(jìn)行拷貝

將這些文件全部都拷貝到我們的新建目錄User文件下

2.4、Keil工程相關(guān)配置

打開(kāi) keil，點(diǎn)擊最上面的 Project 選項(xiàng)卡，選擇 New uVision Project 選項(xiàng)新建一個(gè)工程

選擇保存路徑為我們剛才創(chuàng)建的文件夾下的 Project，文件名為 STM32Template，然后點(diǎn)擊保存

現(xiàn)在我們工程創(chuàng)建好了，下一步選擇對(duì)應(yīng)芯片型號(hào)

確定所需芯片之后，彈出 RTE 的環(huán)境配置對(duì)話(huà)框，選擇工程所需的組件，不用配置,點(diǎn)擊取消

下一步分組創(chuàng)建，將相應(yīng)文件添加到分組中

創(chuàng)建完分組左邊項(xiàng)目覽 如下圖所示，Firmare中存放著我們的標(biāo)準(zhǔn)外設(shè)文件。根據(jù)需要進(jìn)行添加，

需要注意，不同103的啟動(dòng)文件不一樣，根據(jù)自己的型號(hào)進(jìn)行選擇，我這邊是STMF103C6T6,32k內(nèi)存，屬于小容量芯片，選擇startup_stm32f10x_ld.s

如何選擇可以看這下面兩個(gè)圖片，了解自己的芯片內(nèi)存大小選擇合適的啟定文件導(dǎo)入。

導(dǎo)入之后下一步進(jìn)入工程配置

點(diǎn)擊魔法棒，進(jìn)入配置，在Target中選擇V6.21。

output中勾選Browse infomation，勾選之后編譯的時(shí)候自動(dòng)生成hex文件。

在C/C++中按照如下圖進(jìn)行配置，include Path為文件路徑，根據(jù)自己分組進(jìn)行添加。

在Debug選擇自己的燒錄方式

2.5、增加延時(shí)函數(shù)

在User中增加systick.h和systick.c

void delay_decrement(void)

}

打開(kāi)"stm32f10x_it.c"拉到最后，然后刪除

2.6、程序代碼修改

打開(kāi) main.c 文件，刪除一些不必要的代碼，加上系統(tǒng)時(shí)鐘，剩余部分如下：

#include "stm32f10x.h"
#include <stdio.h>
#include "systick.h"int main(void)
{
//系統(tǒng)滴答時(shí)鐘初始化
systick_config();while (1){}
}

在stm32f10x_it.h中添加頭文件systick.h

3、測(cè)試程序

點(diǎn)亮PC13,每秒進(jìn)行亮滅閃爍。

#include "stm32f10x.h"
#include <stdio.h>
#include "systick.h"//PC13 GPIO初始化void gpio_config() {//開(kāi)啟時(shí)鐘RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC,ENABLE); //開(kāi)啟GPIOC的時(shí)鐘//使用各個(gè)外設(shè)前必須開(kāi)啟時(shí)鐘，否則對(duì)外設(shè)的操作無(wú)效/*GPIO初始化*///定義結(jié)構(gòu)體變量GPIO_InitTypeDef 	GPIO_InitStruct;//GPIO引腳，賦值為第13號(hào)引腳GPIO_InitStruct.GPIO_Pin  = GPIO_Pin_13;//GPIO速度，賦值為50MHzGPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;//GPIO模式，賦值為推挽輸出模式GPIO_InitStruct.GPIO_Mode = GPIO_Mode_Out_PP;//將賦值后的構(gòu)體變量傳遞給GPIO_Init函數(shù)GPIO_Init(GPIOC,&GPIO_InitStruct);}int main(void)

}

4、問(wèn)題與解決

1、STM32報(bào)錯(cuò)Error: L6218E: Undefined symbol assert_param

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

在C\C++設(shè)置一欄中輸入U(xiǎn)SE_STDPERIPH_DRIVER使宏生效即可解決問(wèn)題

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

delay_decreme未定義，需要在stm32f10x_it.h中添加頭文件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();
