FPDLINK ke bese e tsamaisang liphapano tsa lebelo le holimo e entsoeng ke TI, haholo-holo e sebelisetsoang ho fetisa lintlha tsa litšoantšo, joalo ka khamera le data e bonts'ang.Tekanyetso e lula e fetoha, ho tloha ho mehala ea pele e fetisang litšoantšo tsa 720P@60fps ho ea ho bokhoni ba hajoale ba ho fetisa 1080P@60fps, ka li-chips tse latelang tse tšehetsang liqeto tse phahameng haholo tsa litšoantšo.Sebaka sa phetisetso le sona se telele haholo, se fihla ho pota 20m, se etsa hore e be se loketseng bakeng sa lits'ebetso tsa likoloi.

FPDLINK e na le mocha o eang pele ka lebelo le phahameng bakeng sa ho fetisa data ea litšoantšo tse potlakileng le karolo e nyane ea data ea taolo.Ho boetse ho na le mocha o khutlelang morao o batlang o le tlase ka lebelo le tlase bakeng sa phetiso ea tlhahisoleseling ea taolo e khutlisetsang morao.Lipuisano tse eang pele le tsa morao li theha mocha oa taolo ea mahlakore a mabeli, e lebisang ho moralo o bohlale oa I2C ho FPDLINK e tla tšohloa pampiring ena.

FPDLINK e sebelisoa ka serializer le deserializer li kopantsoe hammoho, CPU e ka hokela ho serializer kapa deserializer, ho latela ts'ebeliso.Mohlala, ts'ebelisong ea khamera, sensor ea khamera e hokahana le serializer mme e romella data ho deserializer, ha CPU e amohela data e rometsoeng ho tsoa ho deserializer.Ts'ebelisong ea ponts'o, CPU e romella data ho serializer mme deserializer e fumana data ho tsoa ho serializer ebe e e romella skrineng sa LCD hore e bonoe.

CPU's i2c e ka hokahanngoa le serializer kapa deserializer's i2c.The FPDLINK chip e fumana lintlha tsa I2C tse rometsoeng ke CPU ebe e fetisetsa litaba tsa I2C ho isa pheletsong e 'ngoe ka FPDLINK.Joalo ka ha re tseba, ho protocol ea i2c, SDA e hokahanngoa ka SCL.Ka kakaretso lits'ebetso, data e latched moeling o ntseng o phahama oa SCL, o hlokang hore monghali kapa lekhoba le itokisetse data ho tloha moeling o oelang oa SCL.Leha ho le joalo, ho FPDLINK, kaha phetisetso ea FPDLINK e na le nako, ha ho na bothata ha monghali a romela data, hangata lekhoba le fumana data lihora tse 'maloa hamorao ho feta kamoo mong'a e romelang kateng, empa ho na le bothata ha lekhoba le araba mong'a lona. , ka mohlala, ha lekhoba le arabela mong'a lona ka ACK ha ACK e fetisetsoa ho mong'a lona, ​​​​e se e le morao ho feta nako e rometsoeng ke lekhoba, ke hore, e se e fetile ho lieha ha FPDLINK 'me e ka' na eaba e hlolohetsoe ho phahama. moeli oa SCL.

Ka lehlohonolo, protocol ea i2c e nahanela boemo bona.i2c e hlalosa thepa e bitsoang i2c stretch, e bolelang hore lekhoba la i2c le ka hula SCL fatše pele le romela ACK haeba le sa itokisetsa e le hore mong'a lona a hlōlehe ha a leka ho hula SCL e le hore mong'a lona a lule a leka ho hula SCL 'me u emele, Ka hona, ha re hlahloba waveform ea i2c ka lehlakoreng la Lekhoba la FPDLINK, re tla fumana hore nako le nako ha karolo ea aterese ea lekhoba e romeloa, ho na le likotoana tsa 8 feela,' me ACK e tla arajoa hamorao.

TI's FPDLINK chip e sebelisa monyetla ona ka botlalo, ho e-na le ho fetisetsa mofuta oa wave oa i2c o amohetseng (ke ho boloka sekhahla sa baud se tšoanang le sa motho ea rometseng), e fetisetsa data e amohetsoeng ka sekhahla se behiloeng ho chip ea FPDLINK.Ka hona sena ke sa bohlokoa ho elelloa ha ho hlahlojoa sebopeho sa wave sa i2c ka lehlakoreng la FPDLINK Makhoba.Sekhahla sa CPU i2c baud e kanna ea ba 400K, empa sekhahla sa i2c baud lehlakoreng la makhoba la FPDLINK ke 100K kapa 1M, ho ipapisitse le li-setting tse phahameng le tse tlase tsa SCL ho chip ea FPDLINK.
