實(shí)時時鐘是微機(jī)保護(hù)裝置的重要部件,在討論P(yáng)CF8583結(jié)構(gòu)與功能的基礎(chǔ)上,提出采用dsPIC33F系列微處理器與串行I2C時鐘PCF8583的接口設(shè)計方案,給出了相應(yīng)的接口電路與軟件流程。該設(shè)計方案結(jié)構(gòu)簡單,可靠性高,開發(fā)周期短,具有一定的實(shí)用與參考價值。所設(shè)計的微機(jī)保護(hù)裝置已投入現(xiàn)場運(yùn)行,效果良好。
Abstract:
Real-time clock chip is an important part in microcomputer protection device.Based on discussing the structure and function of PCF8583,a new interface scheme which uses dsPIC33F microprocessor and serial clock chip(I2C)PCF8583is proposed.The method of the circuit design and the main software flow are introduced in this paper.The scheme has simple structure,higher reliability and shorter exploitation cycle,so has definite practicality or reference value.The microcomputer protection device has been put into operation with better effects.
