【正文】 64 LCD menu . Experimental results show that the system is stable, unlock and password settings can be achieved through the GSM work to send alarm information, the normal display three menu and the arming and disarming of the zone. Keywords: TC35I, MSP430 microcontroller, menu, password lock 基 于 GSM 網(wǎng)絡(luò)報(bào)警系統(tǒng)設(shè)計(jì) III 目錄 摘要 ............................................................................................................
