FPDLINK bụ ụgbọ ala na-ebufe ihe dị elu nke TI mere, nke a na-ejikarị ebufe data onyonyo, dị ka igwefoto na data ngosi.Ọkọlọtọ a na-agbanwe mgbe niile, site na ahịrị abụọ izizi na-ebufe onyonyo 720P@60fps na ikike izipu 1080P@60fps ugbu a, yana ibe ndị na-esote na-akwado mkpebi onyonyo dị elu.Ogologo nnyefe ahụ dịkwa ogologo, na-eru ihe dịka 20m, na-eme ka ọ dị mma maka ngwa ụgbọ ala.
FPDLINK nwere ọwa na-ebugharị ọsọ ọsọ maka ịnyefe data onyonyo ọsọ ọsọ yana obere akụkụ nke data njikwa.Enwekwara ọwa azụ azụ dị obere obere maka nnyefe ozi njikwa azụ.Nzikọrịta ozi na-aga n'ihu na azụ azụ na-etolite ọwa njikwa bi-directional, nke na-eduga n'ichepụta amamihe nke I2C na FPDLINK nke a ga-atụle n'akwụkwọ a.
A na-eji FPDLINK jiri serializer na deserializer jikọtara ọnụ, enwere ike jikọọ CPU na serializer ma ọ bụ deserializer, dabere na ngwa ahụ.Dịka ọmụmaatụ, na ngwa igwefoto, ihe mmetụta igwefoto na-ejikọta na serializer ma ziga data na deserializer, ebe CPU na-enweta data ezitere na deserializer.Na ngwa ngosi, CPU na-eziga data na serializer na deserializer na-enweta data site na serializer wee ziga ya na ihuenyo LCD maka ngosi.

Enwere ike jikọọ CPU's i2c na serializer ma ọ bụ deserializer's i2c.Mgbawa FPDLINK na-enweta ozi I2C nke CPU zitere wee bufee ozi I2C na nsọtụ nke ọzọ site na FPDLINK.Dị ka anyị maara, na i2c protocol, a na-emekọrịta SDA site na SCL.Na ngwa n'ozuzu, a na-agbanye data na ịrị elu nke SCL, nke chọrọ nna ukwu ma ọ bụ ohu ka ọ dị njikere maka data na njedebe ọdịda nke SCL.Otú ọ dị, na FPDLINK, ebe ọ bụ na FPDLINK na-ebufe oge, ọ dịghị nsogbu ọ bụla mgbe nna ukwu na-eziga data, na kacha nke ohu na-enweta data a ole na ole clocks mgbe nna ukwu zitere ya, ma e nwere nsogbu mgbe ohu ahụ zara nna ya ukwu. , dịka ọmụmaatụ, mgbe ohu ahụ zaghachiri nna ya ukwu na ACK mgbe ACK na-ebufe nna ya ukwu, ọ bụlarị oge karịa oge ohu ahụ zitere, ya bụ na ọ gaferela oge FPDLINK na ọ ga-abụ na ọ na-efunahụ ịrị elu. Ọnụ ego SCL.
Ọ dabara nke ọma, i2c protocol na-eburu ọnọdụ a n'uche.i2c spec na-akọwapụta ihe onwunwe a na-akpọ i2c gbatịa, nke pụtara na ohu i2c nwere ike ịdọrọ SCL tupu izipu ACK ma ọ bụrụ na ọ bụghị njikere ka nna ya ukwu wee daa mgbe ọ na-agbalị ịdọrọ SCL elu ka nna ya ukwu nọgide na-agbalịsi ike. dọrọ SCL elu ma chere maka, Ya mere, mgbe ị na-enyocha i2c waveform na FPDLINK Slave, anyị ga-achọpụta na oge ọ bụla a na-ezigara akụkụ adreesị ohu ahụ, ọ bụ naanị 8 bits, na ACK ga-aza ma emechaa.
Chif FPDLINK TI na-enweta uru nke ọma na njirimara a, kama ibuga naanị i2c waveform natara (ya bụ idobe otu ọnụego baud dị ka onye zitere), ọ na-ebufe data enwetara na ọnụego baud edobere na mgbawa FPDLINK.Ya mere nke a dị mkpa iburu n'obi mgbe ị na-enyocha i2c waveform n'akụkụ FPDLINK Ohu.Ọnụego CPU i2c baud nwere ike ịbụ 400K, mana ọnụ ọgụgụ i2c baud na akụkụ ohu FPDLINK bụ 100K ma ọ bụ 1M, dabere na ntọala SCL dị elu na nke dị ala na mgbawa FPDLINK.
