Los ntawm kev txheeb xyuas i2c waveform ntawm tus qhev, koj tseem yuav pom qhov tshwm sim nthuav dav, thaum nyeem cov ntaub ntawv sau npe, tus qhev yuav xub tshaj tawm nws cov ntawv ua ntej nyeem, piv txwv li, nyeem qhov chaw nyob 0x00 cov ntaub ntawv, koj yuav pom. ntawm lub waveform tom qab tus tswv tau muab qhov chaw nyob sau npe 0x00, ces yuav muab qhov chaw nyob qhev rau kev nyeem ntawv (R/W = (R/W = 1), tus qhev yuav muab 8 SCL waveforms rau nyeem ua ntej tam sim tom qab lub waveform yog tawm, thiab cov 8 teev no tsis sib haum rau ntawm tus tswv sab tus tswv yuav muab tom qab, yog li tus qhev sib npaug rau thawj zaug.
Kev tsim ntawm qhov chaw no yog qhov ntse heev vim tias i2c raws tu qauv qhia tias i2c stretch tuaj yeem tshwm sim hauv cuaj ntsis, uas yog, ACK me ntsis.lub waveform tsis pub rub, thiab tsis muaj cov ntaub ntawv tau txais los ntawm tus qhev ntawm lub sijhawm no, yog li muaj teeb meem.
TI txoj hauv kev yog tias, txij li thaum muaj kev sau ua ntej, ua raws li qhov chaw nyob nyeem qhev xa tam sim tom qab, nws pom tseeb tias qhov chaw nyob sau npe yuav tsum tau nyeem yog daim ntawv sau rau pem hauv ntej, yog li tus tswv yuav xa qhov chaw nyob nyeem qhev. nyob rau hauv 9 ntsis ACK rub thaum xa yim SCLs rau sau npe nyeem thiab sau ntawv, thiab tom qab ntawd tso tawm SCL, tus tswv kuaj pom SCL tso tawm tom qab Tus tswv pom tias SCL raug tso tawm thiab rov xa cov ntawv nyeem cov moos, thaum cov ntaub ntawv xa rov qab mus rau lub CPU.

LVDS Common Terminology los yog Terminology
1) Txawv Pair: Hais txog LVDS teeb liab kis tau tus mob siv ob lub tso zis tsav tsheb los tsav ob kab sib kis, ib qho nqa lub teeb liab thiab lwm tus nqa nws cov teeb liab ntxiv.Lub teeb liab yuav tsum yog qhov sib txawv ntawm qhov hluav taws xob hla ob kab sib kis, uas nqa cov ntaub ntawv teeb liab kom xa mus.
2) Lub teeb liab khub: yog hais txog LVDS interface Circuit Court uas qhov tso zis ntawm txhua cov ntaub ntawv xa mus los yog moos kis tau tus mob yog ob lub teeb liab (qhov zoo thiab qhov tsis zoo)
3) Source: Ib qho khoom siv uas tsim cov ntawv sau, duab, duab, suab, thiab cov ntaub ntawv video.
4) Receiver (Sink): lub cuab yeej ua haujlwm thiab qhia cov ntaub ntawv.
5) FPD-LINK: Flat Panel Display Link, high-speed digital video interface specification raws li LVDS tus qauv tsim los ntawm National Semiconductor hauv xyoo 1996 (tau los ntawm Texas Instruments TI hauv 2011) los txhawb nqa cov ntaub ntawv hloov ntawm cov duab maub los rau LCD vaj huam sib luag.
6) GMSL: Gigabit Multimedia Serial Link, LVDS teeb liab kis raws tu qauv qauv tsim los ntawm Maxim raws li tus qauv LVDS.
7) Forward channel: Cov ntaub ntawv ceev ceev kis tau tus mob los ntawm Serializer mus rau Deserializer.
8) Backchannel: Kuj hu ua Reverse channel, hais txog cov ntaub ntawv xa mus qis qis los ntawm Deserializer mus rau Serializer.
