Komunikacijski vmesnik do gonilnikov svetlečih diod avtomobilskih zadnjih luči

TRUPEJ, GAŠPER (author), Puhan, Janez (mentor)

S tem diplomskim delom smo želeli razviti in izdelati vmesnik, ki samostojno izvaja komunikacijo z gonilniki LED na tiskanih vezjih zadnjih luči avtomobila, in napisati programsko opremo za njegovo delovanje. Naloga vmesnika je, da s pomočjo komunikacije I2C komunicira z gonilniki LED in vklaplja različne funkcije. Izbor vklopljene funkcije določa stroj ICT/FCT z enkratnim pulzom (zastavico) na določenih priključkih vmesnika. Za ostale nastavitve in komunikacijo poskrbi vmesnik samostojno. Končano vezje je pripravljeno za vgradnjo v orodja ICT/FCT, ki se uporabljajo v podjetju. S tem bi se lahko postopek testiranja na različnih projektih podjetja skrajšal, stroški proizvodnje pa zmanjšali. V diplomskem delu je opisan celoten postopek načrtovanja in izdelave tiskanega vezja in razvoj, ter princip delovanja programske opreme komunikacijskega vmesnika I2C.

• Title: Communication interface to LED drivers of car taillights

Abstract

In this diploma thesis, a development and construction of an interface to car taillight LED driver is presented. Hardware and software of the interface are described. The interface can communicate with various LED drivers that can be found on car taillight PCBs. Its purpose is to speed up the taillight testing process. First, an ICT/FCT machine selects taillight function to be tested. The ICT/FCT machine signals its command to the interface with a pulse on the selected input pins. The interface receives the command and adds the required settings. Then it transmits the command further to taillight LED driver which turns on LED diodes of the selected taillight function. For communication between the interface and the LED driver, I2C bus is used. Usage of the interface between the ICT/FCT machine and the LED drivers automates the process of selecting various modes of operation, thus making the testing procedure significantly faster.
