Getting started with the EVSPIN948 dual brushed DC motor driver evaluation board based on the STSPIN948
Introduction
The EVSPIN948 dual brushed DC motor driver evaluation board is based on the STSPIN948. It provides an affordable and easy-to-use solution for the implementation of brushed DC motor driving applications. Thanks to the parallel operation, it can be easily converted to a single brushed DC motor driver with double current capability. In addition to the internal current limiters, the integrated amplifiers allow it to be used in systems with external current control. The EVSPIN948 is compatible with the Arduino UNO R3 connector and most STM32 Nucleo boards.

Compatibility with Arduino UNO R3 connector and STM32 Nucleo boards
The EVSPIN948 board is ready to be used in few steps. Follow this procedure to start your evaluation: 1. Check the setting of the jumpers based on your configuration as described in Section 3 Hardware
description and configuration 2. Connect the board with the STM32 Nucleo board through the Arduino UNO R3 3. Supply the board through the input 2 (VS) and 1 (ground) of the connector CN1

Driving mode selection
The EVSPIN948 can drive up to 2 DC motors at the same time.
The driving mode selection is done setting J5 and J6 jumpers (connected to MODE1 and MODE2 pins of the device) on the top of the boards.

1. The motors can be connected between OUT and either VS (like in the figure) or GND. In the latter case, the current limiter must be disabled. Motors can also be connected between OUT and LSS (without the need of disabling the current limiter), soldering one of the motor cables directly to R12 or R13.
2. This configuration is only available with current limiter in Fixed OFF time mode (see Section 3.2)

(Figure 6) Depending on PWM input signals
In Fixed OFF time mode, the current limiter A and current limiter B can be disabled by setting R6 and R7 to their minimum value respectively.
The current threshold can be set in two different ways:
·
Trimming R41 and R46 resistors, leaving CN9.3 and CN8.4 floating
·
Applying a square wave with variable duty cycle to CN9.3 and CN8.4, setting R41 and R46 to their
minimum value
