Development kit:

1. STM32CubeMX
2. STM32CubeIDE

Instruction

• A new project name LED_BLINKING is created using STM32CubeIDE and STM32CubeMX.
• Board is selected from the board selector in CubeMX so that it can pre-populate all pins that are connected on the board.
• The LED that will be used for this project is determined which is at PA5 and declared it as GPIO Output and the user label is LD2[green_Led].
• Code is generated after all configuration is done.
• In the main loop, HAL functions are called to make the desired LED to blink:
• HAL_Init(); //Reset of all peripherals, Initializes the Flash interface and the Systick.
• SystemClock_Config(); //called the SystemClock function to configure the system clock
• MX_GPIO_Init(); MX_USART2_UART_Init(); //Initialize all configured peripherals
• HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_5); //Toggle the LED
• HAL_Delay(500); // Delay
• 500ms is used to make the LED blink every 1 second
• The code is pushed to the board.
• Reset button is pressed to make the board execute the blinky code.
