luv luv piav qhia:

FPDLINK yog lub tsheb npav sib txawv ceev uas tsim los ntawm TI, feem ntau yog siv los xa cov ntaub ntawv duab, xws li lub koob yees duab thiab cov ntaub ntawv tso saib.Tus qauv yog hloov zuj zus mus tas li, los ntawm thawj khub kab xa tawm 720P @ 60fps dluab mus rau lub peev xwm tam sim no xa mus rau 1080P @ 60fps, nrog cov chips txuas ntxiv txhawb cov duab ntau dua.Qhov kev ncua deb kuj tseem ntev heev, ncav cuag 20m, ua rau nws zoo tagnrho rau kev siv tsheb.

FPDLINK yog lub tsheb npav sib txawv ceev uas tsim los ntawm TI, feem ntau yog siv los xa cov ntaub ntawv duab, xws li lub koob yees duab thiab cov ntaub ntawv tso saib.Tus qauv yog hloov zuj zus mus tas li, los ntawm thawj khub kab xa tawm 720P @ 60fps dluab mus rau lub peev xwm tam sim no xa mus rau 1080P @ 60fps, nrog cov chips txuas ntxiv txhawb cov duab ntau dua.Qhov kev ncua deb kuj tseem ntev heev, ncav cuag 20m, ua rau nws zoo tagnrho rau kev siv tsheb.

FPDLINK muaj lub siab ceev rau pem hauv ntej channel rau kev xa cov duab ceev ceev thiab ib feem me me ntawm cov ntaub ntawv tswj.Kuj tseem muaj qhov qis-ceev rov qab channel rau kev xa rov qab cov ntaub ntawv tswj.Kev sib txuas lus rau pem hauv ntej thiab rov qab tsim ib qho kev tswj hwm ob txoj hauv kev, uas ua rau lub tswv yim zoo ntawm I2C hauv FPDLINK uas yuav tau tham hauv daim ntawv no.

FPDLINK yog siv nrog serializer thiab deserializer ua ke ua ke, CPU tuaj yeem txuas nrog serializer lossis deserializer, nyob ntawm daim ntawv thov.Piv txwv li, hauv daim ntawv thov lub koob yees duab, lub koob yees duab sensor txuas mus rau serializer thiab xa cov ntaub ntawv mus rau deserializer, thaum lub CPU tau txais cov ntaub ntawv xa los ntawm deserializer.Hauv daim ntawv thov zaub, CPU xa cov ntaub ntawv mus rau serializer thiab deserializer tau txais cov ntaub ntawv los ntawm serializer thiab xa mus rau LCD npo rau zaub.

Lub CPU's i2c tuaj yeem txuas nrog serializer lossis deserializer's i2c.FPDLINK nti tau txais cov ntaub ntawv I2C xa los ntawm CPU thiab xa cov ntaub ntawv I2C mus rau lwm qhov kawg ntawm FPDLINK.Raws li peb paub, hauv i2c raws tu qauv, SDA yog synchronized ntawm SCL.Hauv kev siv dav dav, cov ntaub ntawv yog latched ntawm qhov nce ntawm SCL, uas xav kom tus tswv lossis qhev npaj rau cov ntaub ntawv ntawm ntug kev poob ntawm SCL.Txawm li cas los xij, hauv FPDLINK, txij li FPDLINK xa mus rau lub sijhawm, tsis muaj teeb meem thaum tus tswv xa cov ntaub ntawv, feem ntau tus qhev tau txais cov ntaub ntawv ob peb teev tom qab tus tswv xa nws, tab sis muaj teeb meem thaum tus qhev teb rau tus tswv. , piv txwv li, thaum tus qhev teb rau tus tswv nrog ACK thaum ACK raug xa mus rau tus tswv, nws twb dhau los ntawm lub sijhawm xa los ntawm tus qhev, piv txwv li nws tau dhau los ntawm FPDLINK ncua sijhawm thiab tej zaum yuav tsis muaj qhov nce ntxiv. ntug ntawm SCL.

Hmoov zoo, i2c raws tu qauv siv qhov xwm txheej no rau hauv tus account.i2c qhia meej txog cov cuab yeej hu ua i2c ncab, txhais tau hais tias tus qhev i2c tuaj yeem rub SCL ua ntej xa ACK yog tias nws tsis tau npaj kom tus tswv yuav poob thaum sim rub SCL kom tus tswv yuav txuas ntxiv mus. rub lub SCL thiab tos rau qhov, Yog li ntawd thaum soj ntsuam cov i2c waveform ntawm FPDLINK qhev sab, peb yuav pom tias txhua zaus tus qhev chaw nyob xa, tsuas muaj 8 khoom, thiab ACK yuav teb tom qab.

TI's FPDLINK nti siv tag nrho cov txiaj ntsig ntawm qhov tshwj xeeb no, tsis yog tsuas yog xa mus rau qhov tau txais i2c waveform (piv txwv li khaws tib tus nqi baud li tus xa), nws rov xa cov ntaub ntawv tau txais ntawm tus nqi baud teev rau ntawm FPDLINK nti.Qhov no yog qhov tseem ceeb uas yuav tsum nco ntsoov thaum txheeb xyuas i2c waveform ntawm FPDLINK Slave sab.CPU i2c baud tus nqi yuav yog 400K, tab sis i2c baud tus nqi ntawm FPDLINK qhev sab yog 100K lossis 1M, nyob ntawm SCL siab thiab qis qis hauv FPDLINK nti.
