STM32 Black Pill Board | Blinking On-board LED

This blog post is a guide to start your STM32 Black Pill and control the on-board LED using a program on STM32CubeIDE.

Software:

• STM32CubeIDE
• STM32CubeProgrammer

Hardware:

• Desktop or a laptop
• USB-C cable
• STM32 Black Pill

Create a project file.

• Type the project name.
• Choose your preferred programming language, binary type and project type.
• Choose "Add necessary library files" for less errors and problems.

Follow the steps shown in the attachments. And configure the pin-out and clock as per your board and requirement.

Save your file.

• Save your file, this will generate files.
• Go to Core < Src < main.c.

• Go to int main() which is around line 95.
• Change the code inside while(1).

[while(1) is an infinite loop which is used in embedded electronics.]

    HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, 1);
    HAL_Delay(500);
    HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, 0);
    HAL_Delay(500);

• Finally, debug the code.

• Copy the path of .elf file.

• We will bootload STM using USB, this tutorial does not use ST-Link.
• Next, press on "Open file" and select the .elf file from the project folder.
• Press on "Download".

• Go to "Erasing and Programming" from the menu in the left.
• Go to file path and select the .elf file and press "Start automatic mode".

Once compiled, disconnect and reconnect the STM board using USB-C cable.

Voila, your STM32 Board's onboard LED should now start blinking.

Thank you!
