STM32F103 learn the steps and template fool tutorial of 1-keil5 project establishment

1、 Building engineering Folder

Create a new project folder

2、 Create four more folders in the folder

These four folders are for Firmware library and other comparative files

3、 Copy files from the firmware library to CMSIS Folder

Copy the files from the following locations of the firmware to the self created project CMSIS In the folder
After copying , In the self built project documents CMSIS There is 5 File , as follows ：

4、 Copy files to self built projects Start In the folder

Copy the file from the following location in the firmware library , To self built projects Start In the folder
\ Firmware library \STM32F10x_StdPeriph_Lib_V3.5.0\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\startup\arm

After copying, it is as follows

5、 Copy files from the firmware library to Self built projects Lib In the folder

Path as follows ：

Copy these two folders directly To self built engineering projects Lib File at home

6、 Copy files from the firmware library to Self built projects User In the folder

Copy these four files to User in

7、 open keil5, In the file that just created the project , Create a project

Choose chip model

8, Set up a group in the project

Add the file to the corresponding group





Add completed , Click on OK, The file just added appears in the project

9 Initialize configuration

Input STM32F10X_MD,USE_STDPERIPH_DRIVER

Here are two macros defined
USE_STDPERIPH_DRIVER and STM32F10X_MD Two macros , Both Hongs are stm32f10.h in

1. Why define USE_STDPERIPH_DRIVER This macro ？
   The execution of the program is from “main.c” The file started , It must have a header file “stm32f10x.h”.

   We turn on “stm32f10x.h”, Press down “Ctrl+F” key , lookup USE_STDPERIPH_DRIVER, stay “Find What” Enter... In the column “USE_STDPERIPH_DRIVER”.

   As shown in the figure . Click on “Find Next”, appear “USE_STDPERIPH_DRIVER” The corresponding code line , Repeat the above operation three times , The third time we can be in the 8296-8298 Line find the code segment shown in the figure .

This code means , Only pre-defined with precompiled instructions “USE_STDPERIPH_DRIVER”, Will be "stm32f10x_conf.h“ Include in “stm32f10x.h” in , As a result ”main.c“ be used . This explains , Why are we not in “main.c” Contained in the ”stm32f10x_conf.h", But after compiling, it is included in "main.c" in .

"stm32f10x_conf.h“ The file is equivalent to a switch file , If you want to use STM32 Firmware library drives standard peripherals , Then the peripheral driver header file is essential . Such as “stm32f10x_gpio.h”, stay ”stm32f10x_conf.h" We use code #include "stm32f10x_gpio.h" To do this .
stay C/C++ Add... To the predefined “USE_STDPERIPH_DRIVER” Is to allow “ Use standard peripheral drivers ” 了 .

2. How can I automatically define USE_STDPERIPH_DRIVER（ It is not necessary to define in every project USE_STDPERIPH_DRIVER)?
   stm32f10x.h in , Yes ：

#if !defined USE_STDPERIPH_DRIVER 
/** * @brief Comment the line below if you will not use the peripherals drivers. In this case, these drivers will not be included and the application code will be based on direct access to peripherals registers */  
 /*#define USE_STDPERIPH_DRIVER*/  
 #endi

Just put #define USE_STDPERIPH_DRIVER Just remove the comments ！

The startup file is predefined STM32F10X_MD

Tips ： To avoid modifying this file every time you need to switch between these devices , Devices can be defined in the toolchain compiler preprocessor .
- Low density devices are STM32F101xx、STM32F102xx and STM32F103xx Micro controller
among flash The scope is 16-32Kbytes. The corresponding startup file is ：startup_stm32f10x_ld.s

- Low density value-added devices are STM32F100xx Micro controller
among flash The scope is 16-32Kbytes Between . The corresponding startup file is ：startup_stm32f10x_ld_vl.s

- Medium density equipment is STM32F101xx、STM32F102xx and STM32F103xx Micro controller
among flash The scope is 64-128Kbytes Between . The corresponding startup file is ：startup_stm32f10x_md.s

- The medium density line equipment is STM32F100xx Micro controller
among flash The scope is 64-128Kbytes Between . The corresponding startup file is ：startup_stm32f10x_md_vl.s

- High density equipment is STM32F101xx and STM32F103xx Micro controller
among flash The scope is 256-512Kbytes Between . The corresponding startup file is ：startup_stm32f10x_hd.s

- High density value line equipment is STM32F100xx Micro controller
among flash The scope is 256-512 Kbytes Between . The corresponding startup file is ：startup_stm32f10x_ld_vl.s

- Ultra high density devices are STM32F101xx and STM32F103xx Micro controller
among flash The scope is 512-1024 Kbytes Between . The corresponding startup file is ：startup_stm32f10x_xl.s

- Internet based devices are STM32F105xx and STM32F107xx Micro controller . The corresponding startup file is ：startup_stm32f10x_cl.s
