 Hello and welcome to this video explaining how to get started with the Low Voltage Stepper Motor Driver STM32 Nucleo Expansion Board. This board is part of the STM32 Open Development Environment, a fast and affordable way to develop innovative devices and applications with ST components. Information on how to obtain the board can be found on www.st.com.xnucleo under the reference XNUCLEO IHM06A1. The board is built around the ST Spin 220, a stepper motor driver designed for battery powered applications, a power supply and motor bridges connector, a peak current trimmer to adjust the motor torque and a fold LED to check the alarms reported by the ST Spin 220. The board is equipped with an Arduino Uno R3 connector, allowing it to be plugged into an STM32 Nucleo Development Board. First, connect a bipolar stepper motor to the expansion board, taking care to identify each phase as shown here. Then connect a low voltage supply like a 9-volt battery. Next, connect the STM32 Nucleo Development Board to a PC using a mini USB cable. The board is automatically detected and seen as a disk drive. Visit ST.com in search for the keyword XNUCLEO IHM06A1. Click on the main part number link. Then, go to the Tools and Software section and click on the X-Cube link. Finally, go to the end of the page and click on the download button in the Get Software section. In the software package, you will find directories with all the required material. Now, let's try a sample application that allows you to drive a stepper motor connected to a motor driver expansion board. The firmware to be installed is called IHM06A1, example for one motor, and can be found in the examples folder of the projects directory as shown here. Select the STM32 Nucleo Development Board you are using and drag and drop the binary file onto the Nucleo disk drive. Once the firmware is downloaded, the stepper motor will automatically start to move. It will execute the demo sequence which is coded in the main.c file of the project. This sequence includes commands such as moves of a given number of steps in forwards or backwards. A comprehensive set of documentation for the low-voltage stepper motor driver board, including a user manual, application notes, quick start guide, and datasheet is also available.
