This repository illustrates the fundamental use of the GPIO peripheral in STM32 microcontrollers through the HAL framework. It shows how to set pin modes, write and read digital signals, and manage GPIO ports effectively using HAL APIs.

• Based entirely on STM32 HAL (no external libraries)
• Demonstrates input/output configuration, toggling, and pin reading
• Compatible with STM32CubeMX for pin mapping and initialization

aKaReZa 126 – STM32, HAL, GPIO Master the fundamentals of GPIO configuration in STM32 using the HAL Library. This episode walks through pin setup in Input, Output, Alternate Function, and Analog modes, project creation in STM32CubeMX, and practical use of HAL functions like HAL_GPIO_WritePin(), HAL_GPIO_TogglePin(), and HAL_GPIO_ReadPin(). You’ll also learn about timing with HAL_Delay(), troubleshooting common issues, and understanding GPIO Speed for performance optimization—an essential foundation for any STM32 project.

To access the repository files and save them on your computer, there are two methods available:

1. Using Git Bash and Cloning the Repository

   • This method is more suitable for advanced users and those familiar with command-line tools.
   • By using this method, you can easily receive updates for the repository.

2. Downloading the Repository as a ZIP file

   • This method is simpler and suitable for users who are not comfortable with command-line tools.
   • Note that with this method, you will not automatically receive updates for the repository and will need to manually download any new updates.

First, open Git Bash :

• Open the folder in File Explorer where you want the library to be stored.
• Right-click inside the folder and select the option "Open Git Bash here" to open Git Bash in that directory.

• Once Git Bash is open, run the following command to clone the repository:

git clone https://github.com/aKaReZa75/STM32_HAL_GPIO.git

• You can copy the above command by either:
• Clicking on the Copy button on the right of the command.
• Or select the command text manually and press Ctrl + C to copy.
• To paste the command into your Git Bash terminal, use Shift + Insert.

• Then, press Enter to start the cloning operation and wait for the success message to appear.

If you prefer not to use Git Bash or the command line, you can download the repository directly from GitHub as a ZIP file.
Follow these steps:

1. Navigate to the GitHub repository page and Locate the Code button:

   • On the main page of the repository, you will see a green Code button near the top right corner.

2. Download the repository:

   • Click the Code button to open a dropdown menu.
   • Select Download ZIP from the menu.

3. Save the ZIP file:

   • Choose a location on your computer to save the ZIP file and click Save.

4. Extract the ZIP file:

   • Navigate to the folder where you saved the ZIP file.
   • Right-click on the ZIP file and select Extract All... (Windows) or use your preferred extraction tool.
   • Choose a destination folder and extract the contents.

5. Access the repository:

   • Once extracted, you can access the repository files in the destination folder.

If you have any questions or issues, you can raise them through the "Issues" section of this repository. Here's how you can do it:
