Kev Kawm Yog vim li cas Firmware tseem ceeb rau cov koob yees duab Digital
Firmware yog ib qho tseem ceeb rau kev ua haujlwm hnub no ua haujlwm vim nws yog tus software uas qhia cov khoom kho kom zoo li cas. Cov koob yees duab muaj xws li firmware thiab, zoo ib yam li txhua txhua yam khoom siv, nws yog ib qho tseem ceeb uas yuav tau nruab qhov tshiab.
Firmware yog dab tsi?
Lub koob yees duab firmware yog DSLR qhov software yooj yim thiab coding, uas lub koob yees duab txiag nruab thaum lub sijhawm tsim khoom. Tus software muab cia rau hauv "Kev Nyeem Ntawv Xwb" (ROM) ntawm lub koob yees duab, thiab yog li ntawd nws tsis muaj zog ntawm cov roj teeb zog.
Firmware yog lub luag haujlwm ua koj lub koob thaij duab, thiab nws yog qhov tseem ceeb heev. Cov firmware ntsia ntawm koj lub koob yees duab microprocessor tswj tag nrho cov kev khiav dej num los ntawm ntau yam nta rau yam li autofocus thiab cov duab ua.
Vim Li Cas Koj Yuav Tsum Hloov Kho Firmware
Los ntawm cov sij hawm rau lub sijhawm, lub koob yees duab tuam txhab lag luam yuav tso tawm software tshiab, uas yuav tau kho cov koob yees duab los ntawm kev ua kom tau zoo, ntxiv nta tshiab, los yog tseem kho teeb meem. Nws yog ib qho tseem ceeb uas yuav tau saib xyuas cov khoom kho tshiab tsis tu ncua.
Firmware tshiab yog ntsia tau los ntawm kev siv lub computer mus download tau tej yam tshiab mus rau lub koob yees duab ntawm tuam ntxhab ntawm cov websites. Nws raug nquahu kom kuaj xyuas txhua qhov tshiab txhua ob peb lub hlis.
Txawm tias firmware tshiab yog tsim los txhim kho cov kev ua haujlwm ntawm DSLRs lossis lwm hom digital koob yees duab, lawv tsis yog qhov tseem ceeb, thiab qee tus menyuam yaus tej zaum yuav tsis tag li, xws li, piv txwv, ntxiv ib hom lus rau lub tshuab raj uas koj tsis tau ' t tseem hais lus!
Cov Lus Qhia rau Kev Txhim Kho Cov Khoom Siv Hluav Taws Xob
Kev kho mob kuj yuav tsum tau ua kom paub tseeb tias qhov kev hloov tshiab yuav ua haujlwm rau koj lub koob yees duab uas twb muaj lawm. Ib co tshiab yuav tsum muaj qee cov theem ntawm firmware rau twb raug ntsia.
Lwm cov software tshiab yog "thaj av" tshwj xeeb. Koj yuav tsum paub tseeb tias koj txhim kho qhov firmware rau thaj tsam North America (yog tias qhov no yog qhov chaw koj nyob) thiab tsis yog cheeb tsam lwm qhov hauv ntiaj teb los ntawm kev ua yuam kev!
Koj yuav tsum tau dais nco ntsoov tias koj lub koob yees duab uploads tshiab firmware. Qee cov koob yees duab muaj Programmable ROM (PROM), uas cia cov ntaub ntawv tshiab ntxiv rau lub system.
Lwm tus neeg tau hu ua Electronically Erasable PROM (EEPROM) uas tso cai rau cov ntaub ntawv tseem raug tshem tawm. Cov koob yees duab no yog ib qho muaj tseeb, zoo li koj tsis tua nrog firmware tshiab yog tias koj tsis nyiam lawv.
Hloov tshiab nrog Ceev Faj
Thaum twg koj tab tom xaiv ib qho kev hloov tshiab rau koj lub koob yees duab lub tshuab fais fab, nco ntsoov nyeem tag nrho cov lus qhia kom zoo zoo. Txawm tias koj tshawb nrhiav seb puas muaj lwm cov neeg muaj teeb meem nrog kev kho tshiab siv koj lub koob yees duab.
Qhov tseeb, koob yees duab firmware tshiab yuav tsum tau ua nrog kev tu ntau dua, hais ib software hloov tshiab hauv koj lub computer (lossis txawm tias koj lub xov tooj!). Koj tsis muaj kev tswj hwm koj lub koob yees duab uas koj ua koj lub computer, yog li rov muab nws rov qab los rau yav dhau los no tej zaum yuav ua tsis tau rau koj tus kheej.
Phem tshiab tuaj yeem kav koj lub koob yees duab tsis zoo thiab lub koob yees duab yuav tsum xa rov qab mus rau lub khw tsim kho. Ua koj cov kev tshawb fawb ua ntej yuav muab kho dua koj lub koob yees duab qhov firmware!
