Abstract

AUTOSAR Complex Device Driver je komponenta unutar AUTOSAR stoga. Svrha CDD-a je omogućiti izravno povezivanje RTE-a i mikrokontrolera, čime se omogućuje prostor za implementaciju funkcionalnosti koje nisu u sklopu AUTOSAR BSW, a koje ne pripadaju u aplikacijski sloj. U sklopu ovog rada je razvijen AUTOSAR CDD s ciljem povezivanja aplikacijskog sloja AUTOSAR stacka i audio kodeka, dok je krajnja svrha rada upogonjavanje cjelokupnog audio lanca. Audio lanac sastoji se od MCU-a, audio kodeka, audio pojačala i zvučnika. Kako bi se uspješno upogonio audio lanac, potrebno je najprije konfigurirati audio kodek pomoću I2C komunikacijskog protokola, a zatim prenositi digitalne audio podatke koristeći I2S protokol. Aplikacijski sloj AUTOSAR stoga je u sklopu ovog rada demonstriran pomoću Demo SWC-a. Demo SWC je zadužena za generiranje novih audio podataka koji će biti poslani prema audio kodeku. Generirani podaci sačinjavaju pravokutni signal promjenjive frekvencije. Audio kodek će generirane digitalne podatke pretvoriti u izlazni analogni signal te se na izlazu iz zvučnika može čuti zvuk promjenjive frekvencije.

Abstract (english)

AUTOSAR Complex Device Driver is a component within AUTOSAR stack. The main purpose of CDD is to connect RTE and MCU and thus make way for adding custom features that are not a part of the BSW and should not be added in the application layer. Therefore, a CDD has been developed to enable communication between AUTOSAR application layer and audio codec. The final goal is to enable the whole audio chain, which consists of MCU, audio codec, audio amplifier and speaker. To do that the first step is to configure audio codec using I2C communication. After that, I2S data stream can be sent to audio codec. Application layer of AUTOSAR stack was demonstrated using Demo SWC. Demo SWC generated the necessary data and sent it to audio codec. The main task of the audio codec is to convert the digital I2S stream to differential analog signal. Data is generated to make a square wave signal of variable frequency, so a variable frequency sound can be heard from the speaker.
