I-FPDLINK yibhasi yokuhanjiswa kwesantya esiphezulu eyenzelwe yi-TI, eyona nto isetyenziselwa ukuhambisa idatha yesithombe, njengekhamera kunye nedatha yokubonisa.Umgangatho uhlala uvela, ukusuka kwisibini sokuqala semigca ehambisa 720P@60fps imifanekiso ukuya kwisakhono sangoku sokuhambisa i-1080P@60fps, kunye neetshiphusi ezilandelayo ezixhasa izisombululo zemifanekiso ephezulu.Umgama wothumelo nawo mde kakhulu, ufikelela malunga ne-20m, iyenza ilungele usetyenziso lweemoto.

I-FPDLINK ineshaneli ehamba phambili ehamba phambili yokuhambisa idatha yesithombe esiphezulu kunye nenxalenye encinci yedatha yokulawula.Kukwakho nomjelo obuya ngasemva onesantya esisezantsi ukwenzela ukuhanjiswa kolwazi lolawulo olubuyela umva.Unxibelelwano lwangaphambili nasemva lwenza i-channel yokulawula i-bi-directional, ekhokelela kuyilo oluhlakaniphile lwe-I2C kwi-FPDLINK eya kuxutyushwa kweli phepha.

I-FPDLINK isetyenziswe kunye ne-serializer kunye ne-deserializer edibeneyo kunye, i-CPU inokudibaniswa nokuba i-serializer okanye i-deserializer, kuxhomekeke kwisicelo.Ngokomzekelo, kwisicelo sekhamera, i-sensor yekhamera idibanisa kwi-serializer kwaye ithumela idatha kwi-deserializer, ngelixa i-CPU ifumana idatha ethunyelwe kwi-deserializer.Kwisicelo sokubonisa, i-CPU ithumela idatha kwi-serializer kwaye i-deserializer ifumana idatha kwi-serializer kwaye iyithumele kwisikrini se-LCD ukuze sibonise.

I-i2c ye-CPU inokudityaniswa kwi-serializer okanye i-deserializer's i2c.I-chip ye-FPDLINK ifumana ulwazi lwe-I2C oluthunyelwe yi-CPU kwaye idlulisela ulwazi lwe-I2C kwelinye icala ngeFPDLINK.Njengoko sisazi, kwiprotocol ye-i2c, i-SDA ihambelana ne-SCL.Kwizicelo eziqhelekileyo, idatha ifakwe kwinqanaba elikhulayo le-SCL, elifuna ukuba inkosi okanye ikhoboka lilungele idatha kwi-edge edge ye-SCL.Nangona kunjalo, kwi-FPDLINK, ekubeni ukuhanjiswa kweFPDLINK kuphelelwe lixesha, akukho ngxaki xa inkosi ithumela idatha, ubukhulu becala ikhoboka lifumana idatha kwiiwotshi ezimbalwa emva kokuba inkosi iyithumele, kodwa kukho ingxaki xa ikhoboka liphendula inkosi. , umzekelo, xa ikhoboka liphendula inkosi nge-ACK xa i-ACK idluliselwa enkosini, sele sele idlulile ixesha elithunyelwe ngumkhonzi, oko kukuthi, sele sele idlulile ukulibaziseka kwe-FPDLINK kwaye inokuthi iphoswe ukunyuka. umda we-SCL.

Ngethamsanqa, iprotocol ye-i2c ithathela ingqalelo le meko.I-i2c ichaza ipropati ebizwa ngokuba yi-i2c yolula, oku kuthetha ukuba ikhoboka le-i2c liyakwazi ukutsala i-SCL phantsi ngaphambi kokuba ithumele i-ACK ukuba ayilunganga ukuze inkosi ingaphumeleli xa izama ukutsala i-SCL phezulu ukuze inkosi iqhubeke izama tsala i-SCL kwaye ulinde, Ngoko ke xa uhlalutya i-i2c waveform kwicala le-FPDLINK Slave, siya kufumanisa ukuba ixesha ngalinye inxalenye yedilesi yekhoboka ithunyelwa, kukho i-8 bits kuphela, kwaye i-ACK iya kuphendulwa kamva.

Itshiphu ye-TI's FPDLINK ithatha inzuzo epheleleyo yalo mboniso, endaweni yokudlulisela phambili i-i2c waveform efunyenweyo (okt ukugcina umlinganiselo ofanayo we-baud njengomthumeli), iphinda ithumele idatha efunyenweyo kwizinga le-baud elibekwe kwichip ye-FPDLINK.Oku ke kubalulekile ukuqaphela xa uhlalutya i-i2c waveform kwicala leFPDLINK Slave.I-CPU i2c izinga le-baud inokuba yi-400K, kodwa izinga le-i2c le-baud kwicala lekhoboka le-FPDLINK yi-100K okanye i-1M, kuxhomekeke kwi-SCL ephezulu kunye nemimiselo ephantsi kwi-chip ye-FPDLINK.
