External Led Blink Using STM32F401CE

Tody we are using STM32F401CE to Blink an LED , using STM32cubeIDE and HAL programming.

The Material required For this project is:

• STM32F401CE
• C-type Cable
• F-F Jumper Wires
• LED 3v

Open STM32cubeIDE>> file>> New>> STM32 project

After opening new project select the board STM32F401CE

and After Selecting board name your project.

In pinout configration, choose pin PC14 by Clicking it, select its mode as GPIO_OUTPUT.

In system Core >> RCC >> high speed clock(HSE)>>Crystal/ceramic resonator.

In clock configration set clock as shown in figure.

After setting Pinout and configuring clock, save your project by pressing CTRL+S,

New coding file will open.

In while loop write code provided,

Here is the Explanation of code:

1. HAL_GPIO_WritePin(GPIOC,GPIO_PIN_14,1); - This line sets the state of the pin 14 (which is connected to the LED) on GPIO port C to HIGH (1). When the pin is set to HIGH, it provides voltage to the LED, causing it to light up.
2. HAL_Delay(1000); - This line causes the program to wait for 1000 milliseconds, or 1 second. During this time, the LED remains lit.
3. HAL_GPIO_WritePin(GPIOC,GPIO_PIN_14,0); - This line sets the state of the pin 14 on GPIO port C to LOW (0). When the pin is set to LOW, it cuts off the voltage to the LED, causing it to turn off.
4. HAL_Delay(1000); - This line causes the program to wait for another 1000 milliseconds, or 1 second. During this time, the LED remains off.

After writing code, Debug using Hammer option as shown in figure and your coding file is saved as name given in console.

Open STM32cubeProgrammer change ST-LINK to USB and click Connect, while our stm32 board is connected with Your PC by USB

Goto Erasing and Programming option>>browse your file path.

choose option as shown in the picture. Click Start automatic mode.

Your Led will Start blinking .
