Abstract

U ovom radu realizirana je izvedba mikrokontrolera MSP430G2211 (14-pinskog) u svrhu upravljajna sefom. Korištena je tipkovnica 3x4, ali su realizirana samo njena prva 2 reda. Radi malih razina napona kod izlaznih priključaka mikrokontrolera korištene su Schottkyeve diode. Korišten je 2x16 LCD prikaznik na koji se podaci šalju 4-bitnom paralelnom vezom. Za negativan napon pri kontrastu LCD prikaznika korišten je sklop ICL7660. Aktivacija upisivanja lozinke vrši se preko tipke '*'.

Abstract (english)

This paper describes the implementation of a safe deposit box using a microcontroller MS430G2211 (14-pin). The implementation consist of two pheripherals: a 3x4 keyboard and a 2x16 LCD module. Because of the low voltage outputs by the microcontroller the Schottky diode was used while handling the inputs of the keyboard (the rows). Because of the need to have negative voltage for the contrast of the LCD module, ICL 7660 chip was used. The process of writing the password on the LCD module begins by pressing '*' on the keyboard.
