• Click Finish to create the project.
• Configure GPIO:
• Open the generated source code file (e.g., "main.c") in the project workspace.
• Locate the GPIO configuration section.
• Set the GPIO pin(s) you want to use for controlling an LED or any other peripheral. For example, if you want to use Pin PA5, you would typically use the following code:
• Set the GPIO pin(s) you want to use for controlling an LED or any other peripheral. For example, if you want to use Pin PA5, you would typically use the following code:
• Configure GPIO pin PA5 as output
• GPIO_InitTypeDef GPIO_InitStruct = 0;
• __HAL_RCC_GPIOA_CLK_ENABLE(); // Enable GPIO clock
• GPIO_InitStruct.Pin = GPIO_PIN_5;
• GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; // Output push-pull mode
• GPIO_InitStruct.Pull = GPIO_NOPULL; // No pull-up or pull-down
• GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; // GPIO speed (optional)
• HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

Implement the application logic:

Locate the application logic section in the source code.

Use the HAL library functions provided by STM32Cube to control the GPIO pin(s) or any other peripherals you need. For example, to toggle the LED on and off, you could use the following code:

Build and program the application:
