Tehnicko Veleuciliste Zagreb konstrukcijski rad Bozicne lampice
Pri pokretanju programa svijetle led lampice redoslijedom crvena, zelena, žuta u razmaku od 0.2 sekunde i svira melodija we wish You a Merry Christmas. Dovođenjem prekidača sw1 u položaj 0 led lampice se skupa pale i gase također u razmaku od 0.2 sekunde. Ticker služi za provjeru rada programa i treperi plavom led lampicom u razmaku od 0.8 sekundi. Hardverski interrupt radi pritiskom na user button pri čemu program staje na 5 sekundi i pali se led2 na Nucleo pločici. Nakon isteka 5 sek program nastavlja dalje s radom ali led2 ostaje upaljena do ponovog pokretanja interrupat-a.
