STPMC1 evaluation software
Introduction
STPMC1 evaluation software is a graphical user interface to read, configure and calibrate an
STPMC1 energy metering device, suitable for parallel and serial hardware interfaces.
The application has a unique work area where the user can read device registers and write
configuration and calibration parameters.
It is possible to configure application parameters (such as sensor sensitivity, crystal
oscillator frequency) to calculate measured energy, current and voltage.
Data acquisition can be customized to read either a single or a certain number of data
samples from the device. Read data can be output in table format and saved to an Excel file.
Two wizard tools are provided to guide the user during the application design and
automatically calibrate the device.
At any time it is possible to save current session data in a project, to open an existing project
or to create a new project.

Introduction

1.1
Introduction
Prerequisites
This evaluation software is a Windows
®
based application and requires .NET framework
2.0.
It is possible to download and install this framework for free from www.microsoft.com.
1.2
Hardware programmer
The STPMC1 evaluation software can be used with either a parallel or a serial hardware
interface.
The parallel interface is provided free of charge with any STPMC1 demonstration board.
The serial interface, also providing galvanic isolation, is available as a separate
demonstration board with the code STEVAL-IPE005V1.
To communicate with the device through the evaluation software it is necessary to connect a
hardware programmer to both the PC and to the demonstration board, and then the
demonstration board must be powered on.
