Questa ricerca studia l’emulazione dell’interfaccia RGB digitale parallela utilizzando il microcontrollore Aurix™ TC3xx di Infineon, in particolare la variante TC375. Nonostante le caratteristiche avanzate del microcontrollore, manca un supporto nativo per questa interfaccia. Questo studio cerca di risolvere questa limitazione utilizzando il General Timer Module (GTM) della famiglia Aurixtexttrademark, con particolare attenzione alle applicazioni automotive. Una panoramica di Infineon e del suo dipartimento MC di Padova fornisce le basi e spiega le motivazioni alla base della ricerca. Viene approfondita la conoscenza delle basi tecnologiche, evidenziando l’architettura System on Chip Aurix™ TC37x, il GTM e l’interfaccia RGB digitale parallela. Hardware e strumenti chiave come la scheda di sviluppo TC375 Lite Kit di Aurix, l’analizzatore logico Saleae 16 Pro e l’oscilloscopio Tektronix serie 6 sono messi in evidenza per illustrare il loro ruolo centrale nel processo di ricerca. La metodologia di ricerca è dettagliata e comprende considerazioni sulla progettazione del sistema e tecniche di implementazione del firmware. L’obiettivo primario è emulare l’interfaccia RGB a una frequenza di aggiornamento di 100 Hz per immagini in scala di grigi a 8 bit. I risultati confermano la fattibilità dello sforzo di emulazione. I test funzionali verificano la corretta temporizzazione del sistema e l’integrità del segnale. Tuttavia, sono emersi alcuni vincoli, in particolare le limitazioni hardware, come le difficoltà di trasferimento dei dati al GTM a causa del System Peripheral Bus e la mancanza di flessibilità nella selezione del clock dell’interfaccia RGB. Nonostante queste difficoltà, i risultati confermanoil potenziale dell’emulazione con il microcontrollore Aurix™ TC375. Lo studio si conclude evidenziando le implicazioni e proponendo strade per la ricerca futura, suggerendo il passaggio alla serie TC39x e l’esplorazione del supporto di immagini RGB a colori. La sintesi di questa ricerca evidenzia la sua rilevanza per l’emulazione avanzata di interfacce basate su microcontrollori, in particolare nel settore automobilistico.
