Abstract
Sa sve prihvatljivijim cijenama naprednih audio komponenata, otvara se niz mogućnosti za samogradnju. Ovaj rad prikazuje izradu digitalnog audio procesora i kontrole za isti. Korišten je digitalni audio procesor TAS3103, te mikrokontroler STM32F407, uz prateće komponente za prijem i pretvorbu ulaznog signala. Naglasak pri projektiranju je bio na jednostavnosti i praktičnosti korištenja sustava. U sustav ulazi optički signal, pretvara u električni i modificira prolaskom kroz audio procesor. Na izlazu se dobiva signal pripremljen za I2S sabirnicu, koja se dalje prosljeđuje na pojačalo. Mikrokontroler ima ulogu sučelja između krajnjeg korisnika i audio procesora. Služi za primanje koeficijenata sa računala, te prosljeđivanje istih na hardverski ostvarene filtre unutar TAS3103. Koeficijenti se u procesor šalju korištenjem I2C sabirnice, a sa računala se dobivaju korištenjem UART sučelja. Koeficijenti se šalju s računala korištenjem aplikacije koja komunicira s mikrokontrolerom. Pritom je osigurana mogućnost definiranja koeficijenata u zasebnoj tekstualnoj datoteci te učitavanje iste, kao i upis koeficijenata jedan po jedan.
Abstract (english)
As the prices of advanced audio components decrease, a wide range of possibilities for DIY audio opens. This thesis shows one way to build a digital audio processor and a suitable control unit. A TAS3103 digital audio processor and an STM32F407 microcontroller were used, along with corresponding components for reception and conversion of the signal. The focus while designing the system was to make the use as simple as possible for the end user. Entering the system we have an optical signal, which gets converted and modified by passing through an audio processor. The system outputs a signal that is suitable for the I2S bus, which is in turn being passed to an amplifier. The microcontroller servese as an interface between the end user and the processor. It receives the coefficients and passes them to the hardware filters inside the processor. The coefficients are passed from a computer using an UART interface, and then passed to the processor using an I2C bus. On the computer there is an application which communicates with the microcontroller and enables the end user to input the coefficients. The coefficients can be input one by one, or all at once using a text file.
