Liyini i-I2C Bus futhi lisetshenziswa kanjani?

I-I2C Bus (I-Inter-Integrated Circuit) iyiphrothokholi yezokuxhumana evumela ukudluliswa kwedatha. phakathi kwamadivayisi ahlukene electronics kusekethe efanayo ehlanganisiwe. Lesi sixhumanisi sisetshenziswa kakhulu kumasistimu ashumekiwe kanye nama-microcontroller.

Okulandelayo, sizokukhombisa ukuthi ungasebenzisa kanjani i-I2C Bus Igxathu emvakwe gxathu:

• Isinyathelo 1: Xhuma izisetshenziswa: Ukuze usebenzise i-I2C Bus, kufanele uqiniseke ukuthi unamadivayisi ofuna ukuwaxhuma axhumeke ngendlela efanele ngokomzimba. Ukuxhumana kwenziwa ngamapheya amabili ezintambo, eyodwa ukudlulisa idatha nenye ukudlulisa isignali yewashi.
• Isinyathelo 2: Khomba izisetshenziswa: Ngaphambi kokuqala ukusebenzisa i-I2C Bus, kubalulekile ukuhlonza amadivaysi ahlukene axhunywe ebhasini. Idivayisi ngayinye inekheli elihlukile elinikeziwe lokho kusetshenziswa ukuqondisa imilayezo kudivayisi efanele.
• Isinyathelo 3: Qala ukuxhumana: Ukuqala ukuxhumana ngebhasi le-I2C, isignali yokuqala ithunyelwa. Lokhu kubonisa ukuthi wonke amadivayisi ixhumeke ukuthi ukudluliswa kwedatha kuzoqala.
• Isinyathelo 4: Thumela futhi wamukele idatha: Uma ukuxhumana sekuqalile, ungathumela futhi wamukele idatha nge-I2C Bus. Ukuze uthumele idatha, uvele ubhale idatha ofuna ukuyithumela esiteshini sokudlulisela. Ukuze uthole idatha, ufunda idatha ethunyelwa kusukela kudivayisi.
• Isinyathelo 5: Qeda ukuxhumana: Uma usuqedile ukuthumela nokwamukela idatha, kufanele umise ukuxhumana ngebhasi le-I2C. Lokhu kwenziwa ngokuthumela isignali yokuma etshela amadivaysi ukuthi ukudluliswa kwedatha kuqediwe.

Khumbula ukuthi idivayisi ngayinye exhunywe ku-I2C Bus kufanele ihambisane nalesi simiso sokuxhumana. Ngaphezu kwalokho, kubalulekile ukucabangela ukucaciswa kwezobuchwepheshe kwedivayisi ngayinye ukuze kuqinisekiswe ukucushwa nokusebenza okulungile.

Ngalezi zinyathelo ezilula, uzokwazi ukusebenzisa i-I2C Bus ukuxhumana namadivayisi ahlukene ngaphandle kwezinkinga. Thatha ithuba lalesi sikhombimsebenzisi esisebenzayo nesisebenzayo kumaphrojekthi akho e-elekthronikhi.
