# Tutorial: arduino-stm32 Installation ### Overview In this tutorial, you will use arduino IDE compiler to handle several peripherals of MCU (ARM-Cortex M4). Using the given platform, you will perform some tasks about GPIO, timer and interrupt. The objectives of this lab are * Connect STM32F (MCU board) to arduino IDE. * Understand digital in/out peripheral in MCU. * Understand timer and interrupt function of MCU. * Handle GPIO, timer and interrupt using arduino library. ### Hardware ![​ Figure 1.

This USB driver (STSW-LINK009) is for ST-LINK/V2, ST-LINK/V2-1 and STLINK-V3 boards(STM8/STM32 discovery boards, STM8/STM32 evaluation boards and STM32 Nucleo boards). > > It declares to the system the USB interfaces possibly provided by the ST-LINK: ST Debug, Virtual COM port and ST Bridge interfaces. **The driver must be installed prior to connecting the device, in order to have a successful enumeration.** After you download "**en.stsw-link009\_v2.0.2.zip**", unzip the file. Connect MCU board to PC with USB cable. Update the usb driver: 윈도우 **장치 관리자 > 범용직렬버스장치> ST-Link Debug >드라이버 업데이트>** * Select the folder where en-stsw-link009 is unzipped {% hint style="info" %} MCU board (STM32F411) must be connected to your PC to install the USB driver {% endhint %} ![](/files/-Mgmxa6Fa_clUSAF6kAg) > What is ST Link utiliy? #### Connect STM32F401RE through USB port Check the port number and settings in "device manager". * baudrate: 9600 * data bits: 8 * parity: None * Stop bit: 1 * Flow control: None ![image](https://user-images.githubusercontent.com/91526930/186338119-272e8119-cfc5-411e-bce7-7118e94aea96.png) #### Connect STM32F401RE to arduino IDE Arduino Setting for STM32F411RE * Board: Nucleo-64 * Board part number: Nucleo F411RE * Port: USB port number connected with STM32 Board
### Example - Blink There is a simple example, that LED blinks every 1 sec. On menu bar of Arduino IDE, select **File > Examples > 01.Basics > Blink** Then, new window will be opened. If you click **upload** button, the example code will be loaded on the MCU. > If the program is loaded successfully then LED(LD1) will be green light. ![image](https://user-images.githubusercontent.com/91526930/186355557-1e9e137b-03f1-4c8b-8b87-05a4d1c87077.png) \\ ### Troubleshooting Upload Issues #### Step 1: Download & Install STM32CubeProgrammer 📥 Go to the Download Page: Visit the official [STM32CubeProg download page](https://www.st.com/en/development-tools/stm32cubeprog.html). Get the Software: Click "Get Software" to download the latest version. You may need to create a free ST account. Install It: Run the downloaded installer. The default settings are fine, so just click through the installation. The tool will typically be installed at: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer ![STM32CubeProgrammer Installer](https://github.com/user-attachments/assets/15de450e-5e0a-476b-8f14-780054539ef2) #### Step 2: Set Up the Environment Path 🗺️ This step tells your computer where to find the program. Open Environment Variables: In the Windows search bar, type "Edit the system environment variables" and open it. Click "Environment Variables...": A new window will open. Edit the Path: In the "System variables" section, find and double-click on the Path variable. Add the New Path: Click New and add the path to the bin folder from your installation. It should look like this: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin Confirm: Click OK on all windows to close and save the changes.
#### Step 3: Configure Arduino IDE & Upload 🔄 Restart Arduino IDE: This is very important! Completely close and reopen the Arduino IDE for the new settings to take effect. Set the Upload Method: In the Arduino IDE, go to the Tools menu. Board: Make sure your Nucleo-F411RE is selected. Upload Method: Click on this and select STM32CubeProgrammer (SWD). Upload Your Sketch: Try uploading your code again. It should now work perfectly!
