External LED Blink Using STM32F401CE

Let's dive into the exciting world of embedded systems by learning how to make an LED blink using the STM32F401CE microcontroller. This microcontroller is a powerful yet accessible tool for creating all sorts of electronic projects.

we will blink an external LED, using STM32F401CE with HAL programming.

1. STM32F401CE
2. LED 3V
3. Jumper wires M-F
4. C-type Cable

Open STM32cubeIDE>>file>>New>>STM32project.

Select your stm board, after selecting rename it.

set the pin c14 for GPIO_output.

System core>>RCC>>High speed clock(HSE)>>Crystal/ceramic Resonator.

In clock configuration fill the columns shown in the picture.

Now press ctrl+s to open codding file, After this the new code file will open.

HAL_GPIO_WritePin(GPIOC,GPIO_PIN_14,1);

  HAL_Delay(1000);

  HAL_GPIO_WritePin(GPIOC,GPIO_PIN_14,0);

  HAL_Delay(1000);

write this code in while loop.

Click on debug (On top left corner) to generate binary file.

Change ST-Link to USB and click on 'Connect'

Fill the all options shown in picture.
