Posanthula mawonekedwe a i2c a kapolo, mupezanso chodabwitsa kwambiri, powerenga zolembera, kapoloyo amatulutsa mawonekedwe ake kuti awerengeretu, mwachitsanzo, kuwerenga adilesi yolembetsedwa 0x00, mudzawona. pa ma waveform mbuyeyo atapereka adilesi yolembera 0x00, ndiye kuti adzapereka adilesi ya kapolo kuti awerenge (R/W = (R/W = 1), kapolo adzatulutsa ma waveform 8 a SCL kuti awerengedwe posachedwa kuperekedwa, ndipo mawotchi 8 awa sakufanana kumbali ya mbuyeyo omwe mbuyeyo adzaperekedwa pambuyo pake, kotero kapoloyo akufanana ndi kutulutsa koyamba.

Mapangidwe a malowa ndi ochenjera kwambiri chifukwa protocol ya i2c imanena kuti kutambasula kwa i2c kungangochitika pachisanu ndi chinayi, ndiko kuti, ACK bit.mawonekedwe a mafundewa saloledwa kukokedwa, ndipo palibe deta yomwe imalandiridwa kuchokera kwa kapolo panthawiyi, kotero pali vuto.

Njira ya TI ndiyoti, popeza pali cholembera kutsogolo, ndikutsatiridwa ndi adiresi yowerenga kapolo yomwe imatumizidwa mwamsanga pambuyo pake, zikuwonekeratu kuti adiresi yolembedwa kuti iwerengedwe ndi yomwe inalembedwa kutsogolo, kotero mbuyeyo adzatumiza adiresi yowerenga kapolo. mu 9bit ACK kukoka pamene akutumiza ma SCL asanu ndi atatu kuti alembetse kuwerenga ndi kulemba, ndikumasula SCL, mbuye amazindikira kutulutsidwa kwa SCL pambuyo Mbuye azindikira kuti SCL imatulutsidwa ndikutumizanso wotchi yowerengera, pomwe deta imabwezeretsedwa ku CPU.

LVDS Common Terminology kapena Terminology

1) Mitundu Yosiyana: Imatanthawuza kutumiza kwa siginecha ya LVDS pogwiritsa ntchito madalaivala awiri otulutsa kuti ayendetse mizere iwiri yotumizira, imodzi yonyamula siginecha ndi ina yonyamula chizindikiro chake chothandizira.Chizindikiro chofunikira ndikusiyana kwamagetsi pamizere iwiri yotumizira, yomwe imanyamula chidziwitso cha siginecha kuti chitumizidwe.

2) Signal pair: imatanthawuza mawonekedwe a mawonekedwe a LVDS pomwe kutulutsa kwa njira iliyonse yotumizira deta kapena njira yotumizira wotchi ndi ma siginali awiri (zotuluka zabwino ndi zoyipa)

3) Gwero: Chida chomwe chimapanga zolemba, zithunzi, zithunzi, zomvera, ndi makanema.

4) Receiver (Sink): chipangizo chomwe chimayendetsa ndikuwonetsa deta.
5) FPD-LINK: Flat Panel Display Link, mawonekedwe othamanga kwambiri a kanema wa digito kutengera mulingo wa LVDS wopangidwa ndi National Semiconductor mu 1996 (yopezedwa ndi Texas Instruments TI mu 2011) kuti ithandizire kusamutsa deta kuchokera kwa wowongolera zithunzi kupita ku LCD. gulu.

6) GMSL: Gigabit Multimedia Serial Link, mawonekedwe a protocol a LVDS opangidwa ndi Maxim kutengera muyezo wa LVDS.

7) Njira yapatsogolo: Njira yotumizira deta yothamanga kwambiri kuchokera ku Serializer kupita ku Deserializer.

8) Backchannel: Imatchedwanso Reverse channel, imatanthawuza njira yotsika kwambiri yotumizira deta kuchokera ku Deserializer kupita ku Serializer.
