Abstract
U ovom radu detaljno su opisane mogućnosti STM32F4 razvojne pločice u kontekstu sakupljanja, reprodukcije i obrade zvučnih signala. Opisani su postupci konfiguracije potrebih periferija i sabirnica na koje su spojene. Dan je detaljan opis konfiguracije DMA sklopa pločice koji omogućuje oslobađanje procesorkse snage za druge funkcije tijekom prijenosa podataka što je neophodno u aplikacijama sa kontinuiranim snimanjem ili reprodukcijom zvuka. Za ostvarivanje veze pločice na internet korišten je WiFly RN 171 modul čija je konfiguracija detaljno opisana kao i korištenje njegovog instrukcijskog seta u svrhu razvoja aplikacija. Pokazan je primjer upotrebe jednostavnog algoritma za obradu govornih signala kao i upotreba razvijenog programskog sučelja u MatLab-u za analizu kvalitete drugih algoritama. Dan je opis načina rada websocket poslužitelja koji se može upotrijebiti u svrhu povezivanja većeg broja klijenata i razmjene zvučnih podataka.
Abstract (english)
In this paper , we outline the STM32F4 development board in the context of collecting , processing and reproducing of audio signals . Detailed instructions for the configuration of the peripherals and bus to which they are connected are given. The configuration of the DMA circuit plate is defined with the goal of reducing processor load during the transfer of larger amounts of data, which is necessary in applications with continuous recording or playback of sound . To make the connection of the STM32F4 board with the Internet the Wifly RN 171 module was used, describing in detail the configuration as well as the use of its instruction set for the purpose of developing further applications . An example of the use of a simple algorithm with the purpose of processing voice signals is shown as well as the use of a developed programming interface in the MATLAB IDE to analyze the quality of other algorithms . A WebSocket server aplication,with the purpose of connecting a number of clients and the exchange of audio data is described.
