STM32F103ZE Learning record ： Main reference The punctual atoms course

Preface

This note mainly introduces the use ST_SLINK Burn and light up LED Lamp program , And some problems I encountered ,

One 、 Construction of environment

1. Operating steps for creating a new programming file

1.1 In the built project documents , Create a new peripheral folder

Insert picture description here
1.2 In the project folder , Add a path

1.3 establish <.c> and <.h> file

1.4 take <.c> Add file to folder

<.h> The same procedure

2.ST_LINK Burn build

2.1 Click on the magic wand

But I'm using STLINK There was a problem downloading

3.STlink Download appears st-link usb communication error resolvent

The solution is to Firmware upgrade ;

Click on ST-LinkUpgrade.exe, open st-link upgrade Software firmware upgrade

Plug in st-link Firmware to computer , Click on Device Connect Button , Connect st-link

Never put USB Unplug the connector , Otherwise, the upgrade will fail

Insert picture description here
If the following error appears , You can try to plug and unplug again st-link The firmware , Or a different one usb Interface

Successful connection ! Here's the picture , You can see the current firmware version and the version to be upgraded , Click on yes upgrade
Insert picture description here
Update driver

Run as Administrator D:\MDKkeil5\ARM\STLink\USBDriver\stlink_winusb_install.bat file , Update the driver
Insert picture description here
Click next , Until completion .
The problem is solved easily and happily ！

Two 、LED Lantern program

STM32 And 51 SCM is really different ,STM32 than 51 The more advanced ;
STM32 The program directly calls library functions , Than 51 Much more convenient ,STM32 There are many registers in the system , The function is better than 51 To be stronger .
* Operation steps Learn from punctual atoms PPT

In fact, it also operates on registers .

1.LED.c Program

Important functions used * Learn from punctual atoms PPT
Insert picture description here

The code is as follows （ Shown ）：

#include "led.h"
#include "stm32f10x.h"
void LED_Init(void)
{
    
		GPIO_InitTypeDef GPIO_InitStruct;
		RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB,ENABLE);// Can make GPIOB The clock of 
		RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOE,ENABLE);// Can make GPIOE The clock of 
	
		GPIO_InitStruct.GPIO_Mode=GPIO_Mode_Out_PP;// Push pull is selected because it can directly output high level 
		GPIO_InitStruct.GPIO_Pin=GPIO_Pin_5;// choice GPIOB5
		GPIO_InitStruct.GPIO_Speed=GPIO_Speed_50MHz;// The output speed is 50M
	
		GPIO_Init(GPIOB,&GPIO_InitStruct);//GPIOB5 initialization 
	
		GPIO_SetBits(GPIOB,GPIO_Pin_5);// Yes GPIOB5 Set high level 
	
		GPIO_InitStruct.GPIO_Mode=GPIO_Mode_Out_PP;// Push pull is selected because it can directly output high level 
		GPIO_InitStruct.GPIO_Pin=GPIO_Pin_5;// choice GPIOB5
		GPIO_InitStruct.GPIO_Speed=GPIO_Speed_50MHz;// The output speed is 50M
	
		GPIO_Init(GPIOE,&GPIO_InitStruct);//GPIOE5 initialization 
		GPIO_SetBits(GPIOE,GPIO_Pin_5);// Yes GPIOE5 Set high level 
}

2.LED.h Program

The code is as follows （ Shown ）：

#ifndef __led_H
#define __led_H
void LED_Init(void);

#endif

Here I came across a warning , It's very interesting

3…\harwred\led\led.h(7): warning: #1-d: last line of file ends without a newline

This may be MDK A small colored egg left by the developer , Is the last line of code , You must return the train , I feel that person must have OCD .

4.main.c Program

Just call the function

The code is as follows （ Shown ）：

#include "stm32f10x.h"
#include "led.h"
#include "delay.h"
int main(void)
{
    
		LED_Init();// Conduct LED Initialized call 
		delay_init();// Call to initialize the delay function 
		while(1)
		{
    
					GPIO_SetBits(GPIOB,GPIO_Pin_5);// Yes GPIOB5 Set high level 
					delay_ms(500);// Time delay 500 millisecond 
					GPIO_ResetBits(GPIOB,GPIO_Pin_5);// Yes GPIOB5 Set low level 
					delay_ms(500);// Time delay 500 millisecond 
					GPIO_SetBits(GPIOE,GPIO_Pin_5);// Yes GPIOE5 Set high level 
					delay_ms(500);// Time delay 500 millisecond 
// GPIO_ResetBits(GPIOB,GPIO_Pin_5);// Yes GPIOB5 Set low level 
					GPIO_ResetBits(GPIOE,GPIO_Pin_5);// Yes GPIOE5 Set low level 
					delay_ms(500);// Time delay 500 millisecond 
		}
}
