Abstract

Uz uporabu STM32F429I razvojnog sustava cilj je ostvariti samostalnu radnu stanicu za digitalnu obradu signala u sučeljima mozga. Prijenos signala se odvija preko analogno-digitalnog pretvornika ADS1252 te se navedeni signal obrađuje primjenom brze Fourierove transformacije (engl. Fast Fourier Transformation, FFT). Cilj transformacije je mogućnost klasifikacije primljenih signala po frekvencijskoj karakteristici. Konačni cilj je postići jasan prikaz rezultata obrade na 2,4 inčnom QVGA TFT LCD zaslonu koji se nalazi na samom razvojnom sustavu STM32F429I, gdje će se pojava svake frekvencije brojati u obliku stupaca.

Abstract (english)

The embedded system STM32F4 microcontroller primary use is accomplishing the independent workstation for EEG digital signal processing. Signal input is achieved through differential amplifier and analog-digital converter ADS1252. Furthermore, the EEG signal is processed through Fast Fourier Transform algorithm and substantially categorized according to its frequency. The end goal is achieving a clear display of the results on embedded 2.4-inch LCD display through usage of bars and text.
