Supplies

STM32CubeIDE
STM32 Black Pill
STM32CubeProgrammer
C-Type cable
Breadboard
3 LEDs
Jumper wires

Step 1: Creating a New Project

Open STM32CubeIDE>Goto files>click New>select STM32 Project

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 Pins for output .(here I used PA10,PA11,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 pins)

Step 8: Writing Code

Write the code in while loop.

Code:

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.
