 Welcome to this explainer video on the STM32 Nucleo Motor Control Expansion Board using Arm Embed Environment. During this video, we will show you how to drive a bipolar stepper motor. We are going to explain how to get your application running in the Arm Embed Environment. The first half of the video will focus on the software setup and the second half will detail the hardware functionality available. Now, connect one bipolar stepper motor to the expansion board. Then, connect a voltage supply. In this case, we use a 12 volt supply. Then you can connect the STM32 Nucleo Board to a PC using a mini USB cable. And then, you are ready to power on. The board is automatically detected and seen as a disk drive. Now, connect to the armdeveloper.embed.org website and log in with your credentials. Click on Hardware, then Components, and select Motor under the actuators category. Click on XNucleo IHM05A1 Bipolar Stepper Motor Driver and find the Hello World underscore IHM05A1 application example on the next page. Then, import it into the online compiler. Open the main program and choose the desired target platform. Add a new one if needed. At this point, build the application and download it on the Nucleo Board. After completing download or when pressing the black button on the Nucleo Board, the application will reset and start. This simple application shows how to run the bipolar stepper motor at different speeds. And now, some details about the STM32 Nucleo Bipolar Stepper Motor expansion board. It includes a fully integrated Demos stepper motor driver, the L6208. At www.st.com.x-nucleo under the reference XNucleo IHM05A1, you can find user manuals, quick start guides, bill of materials, and lots of other detailed documentation to help you on your way to building your application. Thanks for watching. We hope we helped you get started on your dream application.
