This repository contains a bare-metal STM32 project. It controls an LED on the STM32F446RET6 microcontroller by manipulating hardware registers directly. You do not need to use HAL or CubeMX, making it a straightforward option for testing and learning.
To begin, you need to download the program. This guide will help you do that step by step.
- A computer with Windows or Linux installed.
- An STM32F446RET6 microcontroller.
- Basic familiarity with connecting microcontrollers.
- A USB debug adapter, such as ST-Link, to upload the code.
- Visit the Releases page to download the latest version.
- On the Releases page, look for the latest version. Click on it to see the available files.
- Download the file best suited for your needs. This will typically be a
.binor.hexfile format. - After downloading, connect your STM32F446RET6 microcontroller to your computer using the USB debug adapter.
- Use the appropriate software to upload the downloaded file to your microcontroller.
Here are detailed steps on how to upload the program to your microcontroller:
- Install ST-Link Utility or STM32CubeProgrammer:
- Download and install the ST-Link Utility or STM32CubeProgrammer from the STMicroelectronics website.
- Connect the Microcontroller:
- Connect the STM32F446RET6 to your computer using the USB debug adapter.
- Open the Upload Software:
- Launch the ST-Link Utility or STM32CubeProgrammer.
- Select the File:
- Click on "Open" and navigate to the location of the downloaded file.
- Upload the File:
- Click on "Program" to upload the file to the microcontroller.
- Verify the Upload (optional):
- You can select the "Verify" option to ensure the upload was successful.
- Disconnect and Power On:
- After uploading, disconnect the USB debug adapter and power on the microcontroller to see the LED blink.
Here is a simple connection diagram to help you set up your STM32F446RET6 microcontroller:

This project uses bare-metal programming to control an LED. Unlike higher-level frameworks such as HAL, direct register manipulation allows for more efficient and faster operations.
- GPIO Control: The General Purpose Input/Output (GPIO) registers control the LED. You can set these registers to turn the LED on or off.
- Timing: A simple loop with delays manages the blinking, so the LED turns on for a brief moment and then turns off.
If you encounter issues, consider the following:
- Check Connections: Ensure all connections between the debugger and the microcontroller are secure.
- Drivers: Make sure any necessary drivers for the ST-Link are installed.
- Power Supply: Verify the microcontroller is receiving adequate power.
