摘要
设计一种带在手腕上将手表和无线门铃合二为一的手表门铃。该系统以MSP430G2553单片机为控制核心,采用DS1302时钟芯片提供时间,利用PT2262/2272的无线发收模块分别发射和接收门铃信号,使用OLED12832来显示时间、闹铃和门铃方式,并通过扬声器、LED和小型直流电机分别进行声音、闪光和振动等门铃提示。
A watch doorbell on your wrist com- bined watch with wireless doorbell is described. The system uses a MSP430G2553 microcontroller as the control core, uses a DS1302 clock chip to provide the time,uses PT2262 / 2272 wireless sending and receiv- ing modules respectively to transmit and receive the doorbell signal, uses an OLED12832 to display the time, alarm and doorbell mode, and uses speakers, an LED and small DC motor to make a doorbell prompt with sound, flash or vibration.
