Using STM32 motor control workbench with STSPIN32F0
and STSPIN32F0A
Introduction
The STSPIN32F0 and STSPIN32F0A are systems-in-package providing an integrated
solution suitable for driving 3-phase BLDC motors using different driving modes. The
integrated MCU (STM32F031x6) allows the performance of field-oriented control.
This document explains how to drive the STSPIN32F0 or STSPIN32F0A with FOC
algorithms, using the STM32 motor control workbench software to generate all the
parameter header files, to configure the STM32 PMSM FOC library according to application
needs.
To drive a motor with FOC algorithms using the STSPIN32F0 or STSPIN32F0A device,
follow this simple workflow:
1. Set up the hardware.
2. Use STM32 motor control workbench to configure the library and generate the code.

1 Set up hardware
Choose the board according to the target: you can use the ST STEVAL-SPIN3201 or
STEVAL-SPIN3202 boards or you can use a custom board;
Connect the board, power supply and plug in your motor.
2 Use STM32 motor control workbench to configure
the library and generate the code
The STM32 motor control workbench can be used to configure the FOC firmware library to
use in your application. The user can use the STEVAL-SPIN3201 or STEVAL-SPIN3202
boards or a custom board can be used.
2.1 Create new project for ST STEVAL-SPIN3201 board
The STEVAL-SPIN3201 board is a three-phase brushless DC motor driver board based on
the STSPIN32F0, a 3-phase controller with an integrated STM32 MCU.
The device provides an affordable and easy-to-use solution for the evaluation of the device
in low voltage motor driving applications such as fans, drones and power tools.
The board is designed for sensored or sensorless FOC algorithms with 3-shunt sensing. To
create a new project for the STM32 motor control workbench based on STEVAL-SPIN3201,
follow the procedure:
Open the STM32 motor control workbench v5.2;
Click on “New Project” and a parameter window appears;
Choose the “Inverter” board type and select the STEVAL-SPIN3201 from the dropdown
list (Figure 2). In this way, the application automatically loads all the hardware-related
parameters for the FOC library.
Figure 2. Parameter window for STEVAL-SPIN3201
From the motor list, one of the pre-configured motors or a generic starting model can
be selected (Figure 3);
Use STM32 motor control workbench to configure the library and generate the code UM2168

Figure 3. Pre-configured motor window
Click OK. A new project is now created according to the starting parameters selected.
A configuration window appears, allowing the parameters to be set for:
– “Motor”
– “Power Stage”
– “Drive Management” (i.e. FOC algorithm configuration)
– “Control Stage” (i.e. MCU configuration)
Using the STEVAL-SPIN3201 device, the configuration parameters for the Power Stage,
Drive Management, and Control Stage are already set.
2.2 Create new project for ST STEVAL-SPIN3202 board
The STEVAL-SPIN3202 board is a three-phase brushless DC motor driver board based on
the STSPIN32F0A, a 3-phase controller with integrated STM32 MCU.
The device provides an affordable and easy-to-use solution for the evaluation of the device
in low voltage motor driving applications such as fans, drones and power tools.
The board is designed for the sensored or sensorless FOC, with single shunt current
sensing.
To create a new project for the STM32 motor control workbench based on STEVAL-
SPIN3202 follow the procedure:
Open the STM32 motor control workbench v5.2;

To use the integrated MCU (STM32F031x6), remember that a limited number of pins
can be accessed, as can be seen in the STSPIN32F0 or in the STSPIN32F0A
datasheet. Here is a list of pins that can be used to access the integrated MCU for both
devices:

2.4 Customize parameters for application needs
When a project is opened by the STM32 motor control workbench, a configuration window
appears allowing the user to easily manage parameters for the FOC firmware library. There
are 4 families of parameters that should be changed to best fit the characteristics of the
application.
Figure 8. STM32 motor control workbench configuration window
2.4.1 Motor parameters
In the configuration window the motor parameters can be manually inserted by clicking on
the motor symbol and filling the fields (Figure 9). If “save parameters” is clicked on, the user
can add their motor to the preset list of motors.
