Iyo usesenguye imiterere ya i2c yumucakara, uzasangamo kandi ibintu bishimishije cyane, mugihe usoma amakuru yanditswe, umugaragu azabanza gutanga umurongo wacyo kugirango ubanze usome, kurugero, kugirango usome aderesi yanditswe 0x00, uzabona kuri flake nyuma yuko shebuja atanze aderesi yandika 0x00, hanyuma agatanga aderesi yumucakara kugirango asome (R / W = (R / W = 1), umugaragu azatanga 8 form ya SCL kugirango abanze asome ako kanya nyuma yumurongo wamazi ni yatanzwe, kandi aya masaha 8 ntabwo ahuye kuruhande rwibanze shebuja azatangwa nyuma, bityo umugaragu ahwanye no gutanga mbere.

Igishushanyo cyahantu hafite ubwenge cyane kuko protocole ya i2c iteganya ko i2c kurambura bishobora kugaragara gusa muri cyenda biti, ni ukuvuga ACK bit.imiterere ya wave ntabwo yemerewe gukururwa, kandi nta makuru yakiriwe kuva kumugaragu muriki gihe, harikibazo rero.

Uburyo bwa TI ni uko, kubera ko hari igikorwa cyo kwandika imbere, kigakurikirwa na aderesi y’umugaragu yasomwe ako kanya nyuma, biragaragara ko aderesi yanditswe igomba gusomwa ari iyanditswe imbere, bityo shebuja azohereza aderesi y’umugaragu yasomwe muri 9bit ACK gukurura mugihe wohereje SCL umunani zo kwiyandikisha gusoma no kwandika, hanyuma ukarekura SCL, shobuja amenya irekurwa rya SCL nyuma yuko shebuja amenye ko SCL yarekuwe kandi ikohereza isaha yasomwe, hanyuma amakuru agasubizwa kuri CPU.

LVDS Amagambo asanzwe cyangwa Amagambo

1) Itandukaniro Ryombi: Yerekeza kuri LVDS yoherejwe hakoreshejwe ibimenyetso bibiri bisohoka kugirango utware imirongo ibiri yoherejwe, imwe itwara ibimenyetso indi itwara ibimenyetso byuzuzanya.Ikimenyetso gisabwa ni itandukaniro rya voltage hejuru yimirongo ibiri yoherejwe, itwara amakuru yikimenyetso cyoherezwa.

3) Inkomoko: Igikoresho gitanga icyegeranyo cyinyandiko, ibishushanyo, amashusho, amajwi, na videwo.

4) Kwakira (Sink): igikoresho gitunganya kandi kigaragaza amakuru.
5) FPD-LINK: Ihuza rya Flat Panel, Ihuza ryihuta rya videwo yerekana amashusho yihuse ashingiye ku gipimo cya LVDS cyakozwe na National Semiconductor mu 1996 (cyaguzwe na Texas Instruments TI muri 2011) kugirango gishyigikire amakuru yoherejwe kuva mugenzuzi ushushanya kuri LCD. Umwanya.

6) GMSL: Gigabit Multimedia Serial Ihuza, imiterere ya LVDS yerekana itumanaho rya protocole yakozwe na Maxim ishingiye kubipimo bya LVDS.

7) Imiyoboro yimbere: Umuyoboro wihuse wohereza amakuru kuva muri Serializer kugera kuri Deserializer.

8) Umuyoboro winyuma: Nanone witwa umuyoboro wa Reverse, bivuga umuyoboro muto wohereza amakuru kuva kuri Deserializer ukagera kuri Serializer.
