20.500.12556/RUL-148926 Preizkušanje integriranih vezij za matrično krmiljenje svetlečih diod v avtomobilskih žarometih Evaluation of integrated circuits for matrix LED control in automotive headlight applications V avtomobilski industriji je vedno bolj pogost trend žarometov z animacijo pri prižigu in izklopu luči. Te animacije velikokrat zahtevajo žaromet, ki vsebuje krmilnik ter programsko opremo, razvoj te pa je zelo drag in zamuden. Z uporabo namenskih integriranih vezij lahko žaromet upravljamo z ukazi iz avtomobilskega krmilnika in se tako izognemo razvoju programske opreme v samem žarometu. V sklopu diplomske naloge smo v podjetju Hella Saturnus Slovenija preučevali in testirali delovanje teh integriranih vezij ter izdelali žaromet, ki temelji na njih. Uporabljeni sta bili integrirani vezji TPS929120 in TPS92664. Njuna komunikacija temelji na UART (univerzalni asinhroni sprejemnik oddajnik) protokolu, ampak se struktura sporočil razlikuje. Cilj diplomske naloge je izdelati žaromet, ki poveže obe integrirani vezji na eno komunikacijsko linijo, in pošiljati sporočila za upravljanje svetlečih diod. Izkazalo se je, da sporočilo, namenjeno prvemu integriranemu vezju, povzroči napako ali napačno interpretacijo drugemu. Možne rešitve so pošiljanje samo enega bajta, ponovni zagon komunikacije in pošiljanje sporočil z različno frekvenco. The trend for headlights with animation when the lights are switched on and off is becoming increasingly common in the automotive industry. These animations often require a headlamp containing a controller and software, which is very expensive and time-consuming to develop. Using dedicated integrated circuits, commands can be sent from the car's controller, thus eliminating the use of software in the headlamp itself. As part of our thesis, we have studied and tested the operation of these integrated circuits at Hella Saturnus Slovenia and built a headlamp based on them. The integrated circuits used were TPS929120 and TPS92664. Their communication is based on the UART (universal asynchronous receiver transmitter) protocol, but they differ in message structure. The aim of the thesis is to design a headlamp that connects both devices to a single communication line and send messages to control the LEDs. It turns out that a message intended for the first integrated circuit causes an error or misinterpretation for the second. Possible solutions are sending only one byte, restarting the communication, or sending messages with different frequencies.
