I2C Nedir?<\/strong><\/p>\n\n\n\n

I2C veriyolu \u00e7ok master\u2019l\u0131 (multi-master) veri yoludur. Yani, birden fazla say\u0131da data transferini ba\u015flatabilme \u00f6zelli\u011findeki t\u00fcmdevre, veriyoluna ba\u011flanabilir. Bu durumda data(\u201cveri\u201d diyelim ki daha T\u00fcrk\u00e7e olsun) transferini ba\u015flatan t\u00fcmdevre(IC-Integrated Circuit) Bus-Master(Veriyolu Efendisi) durumunda olacak, veriyolundaki t\u00fcm di\u011fer IC\u2019ler ise Bus-Slave(Veriyolu K\u00f6leleri) durumunda olacakt\u0131r.<\/p>\n\n\n\n
