Supplies

1.STM32 Black Pill

2.STM32CubeIDE

3.STM32CubeProgrammer

4.C-type cable

5.LED

6.Jumper Wire

Step 1: Creating a New Project

  • Open STM32CubeIDE>click on files>select>new>stm32 projects



Step 2: Adding MCU/MPU Selector Features for STM32 Project

  • Enter the Commerical Number of STM32 you want to work with( used Commerical Number in this project:STM32F401CCU6)
  • Select the required type of configuration of STM32.
  • Then click next.
  • A dialogue box appears >type the name of the project
  • The project file is created to work on it.


Step 3: Pinout Configurations

  • Select RCC from System Core.
  • Select the Cereamic/crystal response in High speed clock.
  • Some configurations wlll be added ,i.e,RCC_OSC_IN & RCC_OSC_OUT ON STM32 board of cubeide.
  • Select the Pin number for output .(here I used PA12).


Step 4: Clock Configuration

  • Select clock configuration.
  • Select HSE and PLLCLK in PLL Source MUX & System Clock MUX respectively.
  • Then select resolve clock issues.

Step 5: Generating the Code

  • Select the project from dialogue box.
  • Select generate code option from it.
  • The code gets generated.

Step 6: Creating .Ioc File

  • Select the file you working on (from the left side)>right click on it.
  • A option box appears>select properties.
  • Then the dialogue box opens >select the C/C++ Build (from left side of it).
  • Select settings>MCU Post build Ouput
  • Choose the options shown in the image.
  • Then apply and close.
  • The .ioc file is created.

Step 7: Main.c

  • Select the core from the File .
  • Go to Src>select main.c.
  • Main.c gets open to write code.(A code is generated already to help you in the configuration and to identify pin numbers you selected as output pin)


Step 8: Writing Code

  • Write the code in while loop.

Code:

HAL_GPIO_WritePin(GPIOA,GPIO_PIN_12,0);

{HAL_Delay(500);}

HAL_GPIO_WritePin(GPIOA,GPIO_PIN_12,1);

{HAL_Delay(500);}


Step 9: Debug the Code

  • Select Build >select option 1.debug

Step 10: Copying the Path Of.elf File

  • After debuging the ;if any error arises then remove all the error and if no error comes then go to .ioc file.
  • Select .ioc file right click on it ,a option box appears.
  • Select show in>system explorer.
  • Files will be opened.
  • Select the .elf file and copy its path.

Step 11: Adding the .elf on STM32CubeProgramer

  • Open the STM32CubeProgrammer.
  • Select the Open file option >paste the path copied of .elf file there.
  • File is added.

Step 12: Breadboard Connection

  • Place the Stm32 on breadboard.
  • Connect the LED with STM32 by the pin given in STM32CubeIDE.
  • Ground the LED with the ground pin from STM32.

Step 13: Connect the STM32

  • Connect the STM32 Black pill with Laptop.
  • Connect it with STM32CubeProgrammer by USB.
  • BOOT the STM32 to connect it.
  • After connecting click on Connect.

Step 14: Download the File

  • Goto Download>paste the copied of .elf file here also
  • Click on Start Automatic Mode.

Step 15: LED Starts Blinking

  • Disconnect the STM32.
  • Then connect again and you will see that the LED is blinking.
