Cov EEPROM data nco tso cai byte nyeem thiab sau . Ib byte sau cia li tshem tawm qhov chaw thiab sau qhov tshiab cov ntaub ntawv (luag ua ntej sau ). Cov EEPROM data nco yog ntsuas rau siab erase/ sau lub voj voog. Cov sau lub sij hawm yog tswj los ntawm ib tug on-chip timer.
Tib neeg kuj nug, koj nyeem thiab sau eeprom li cas?
Kev nyeem ntawv los ntawm EEPROM yeej ua raws li peb kauj ruam txheej txheem raws li kev sau ntawv rau EEPROM:
- Xa qhov tseem ceeb tshaj plaws Byte ntawm lub cim xeeb chaw nyob uas koj xav sau rau.
- Xa qhov tsawg kawg nkaus Byte ntawm lub cim xeeb chaw nyob uas koj xav sau rau.
- Nug cov ntaub ntawv byte ntawm qhov chaw ntawd.
Kuj Paub, cov ntaub ntawv khaws cia hauv eeprom li cas? EEPROM stands rau Electronically Erasable Programmable Read Only Memory uas yog ib hom kev nco tsis hloov pauv siv nyob rau hauv ntau yam khoom siv hluav taws xob rau khw kuj me me ntawm cov ntaub ntawv . Cov EEPROM tso cai rau cov ntaub ntawv yuav tsum tau nyeem, sau thiab tshem tawm ntawm qib byte. ATmega328/P muaj 1K bytes ntawm EEPROM nco.
Kuj Paub, nyeem thiab sau eeprom hauv Arduino li cas?
EEPROM Sau . Lub microcontroller ntawm lub Arduino thiab Genuino boards muaj 512 bytes ntawm EEPROM : lub cim xeeb uas nws qhov tseem ceeb khaws cia thaum lub rooj tsavxwm raug muab tua (zoo li lub hard drive me me). Qhov piv txwv no qhia txog kev khaws cov txiaj ntsig nyeem los ntawm analog input 0 rau hauv EEPROM siv cov EEPROM . sau () ua haujlwm.
Kuv yuav tshem eeprom li cas?
EPROM feem ntau yog hlawv tawm-ntawm-circuit nyob rau hauv lub programming fixture. Thaum lub sij hawm los txog lwv tus EPROM , cia li pop nws nyob rau hauv ib lub teeb ultraviolet (UV) rau 30 feeb, thiab koj npaj rov mus dua. Cov EPROM cov quartz qhov rais tso cai rau UV teeb tawm tsam silicon tuag, tshem tawm lub cim xeeb.

Dab tsi yog qhov sib txawv ntawm cov ntaub ntawv sib sau ua ke thiab cov ntaub ntawv tsis sib xws?
Kev sib sau cov ntaub ntawv yog sau thiab sau cov ntaub ntawv; kom disaggregate cov ntaub ntawv yog rhuav tshem cov ntaub ntawv sib sau ua ke rau hauv cov khoom siv lossis cov ntaub ntawv me me
Koj puas tuaj yeem nyeem thiab sau cov ntaub ntawv los ntawm ROM?
Muaj ntau hom tshuab siv rau Kev Nyeem Tsuas Nco (ROM). Nws tsis yog tsim los sau sai thiab nquag xws li Random Access Memory (RAM). Tab sis ROM tsis yog-volatile thiab khaws nws cov ntsiab lus thaum lub hwj chim tawm. Cov txheej txheem ntawm kev ua haujlwm ROM qeeb vim tias nws ua tiav ib zaug lossis tsis tshua muaj
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Vim li cas cov ntaub ntawv zoo tseem ceeb heev rau kev sau cov ntaub ntawv txheeb cais?
Cov ntaub ntawv muaj txiaj ntsig zoo yuav ua kom muaj txiaj ntsig ntau dua hauv kev tsav lub tuam txhab kev vam meej vim yog kev vam khom ntawm qhov tseeb-raws li kev txiav txim siab, tsis yog kev coj cwj pwm lossis tib neeg kev xav. Ua kom tiav: Xyuas kom tsis muaj qhov khoob ntawm cov ntaub ntawv los ntawm qhov yuav tsum tau sau thiab qhov twg tau sau tiag
Nws puas tuaj yeem nyeem los ntawm thiab sau rau qhov chaw nyob hauv cov ntaub ntawv siv Java?
Siv cov ntaub ntawv nkag mus random, peb tuaj yeem nyeem los ntawm cov ntaub ntawv thiab sau rau hauv cov ntaub ntawv. Kev nyeem ntawv thiab sau ntawv siv cov ntaub ntawv tawm tswv yim thiab tso tawm cov kwj deg yog cov txheej txheem ua ntu zus. Siv cov ntaub ntawv nkag mus random, peb tuaj yeem nyeem lossis sau ntawm txhua txoj haujlwm hauv cov ntaub ntawv. Ib yam khoom ntawm RandomAccessFile chav kawm tuaj yeem ua cov ntaub ntawv nkag mus
