I2C raws tu qauv
Nws feem ntau yog siv los sib txuas lus ntawm cov khoom ntawm motherboards hauv cov koob yees duab thiab hauv ib qho kev siv hluav taws xob. Peb siv xws li ib tug XOV XWM - qhev kev sib txuas los txo cov haujlwm ua haujlwm ntawm ib qho Arduino , los yog txuas ntxiv sensors rau qhov project thiab lwm yam.
Yog li ntawd, kuv yuav ua li cas paub nrog Arduino?
Yam yuavtsum tau kawm uantej kom paub txog Arduino:
- Kev paub yooj yim ntawm cov lus programming zoo li (Embedded C)
- Qee qhov kev paub keeb kwm yav dhau los ntawm MP-MC (lub cev Architecture, lwm yam khoom siv)
- Sim programming MP-MC siv Embedded C, keil uas pab koj nkag siab txog kev ua haujlwm yooj yim.
- Sim cuam tshuam qee yam xws li LED, 7-SEGMENT DISPLAY, LCD, KEYPAD thiab lwm yam.
Tsis tas li ntawd, SDA thiab SCL pins yog dab tsi? Teb Lub Plaub Hlis 30, 2019. Hauv Arduino Uno, SCL thiab SDA pins yog I2C lossis IIC tus pin . I2C stands rau Inter Integrated Circuits thiab nws yog nrov heev ob hlau (TWI) serial kev sib txuas lus raws tu qauv. SCL stands rau Serial Clock. SDA sawv cev rau Serial Data.
Hais txog qhov no, dab tsi yog tus tswv thiab qhev hauv Bluetooth module?
Bluetooth networks (feem ntau hu ua piconets) siv a tus tswv / qhev qauv tswj thaum twg thiab qhov twg cov khoom siv tuaj yeem xa cov ntaub ntawv. Hauv cov qauv no, ib leeg tus tswv ntaus ntawv tuaj yeem txuas mus txog xya qhov sib txawv qhev khoom siv. Ib qho qhev ntaus ntawv hauv piconet tsuas yog txuas nrog ib leeg xwb tus tswv.
Puas yog Arduino nyuaj kawm?
Rau ntau tus neeg, nws yog ib qho kev ntxhov siab. Txoj xov zoo yog qhov ntawd Arduino code zam txim. Nws tseem muaj qhov kev kawm nkhaus, thiab nws tsis yooj yim raws nraim, tab sis nws yog qhov yooj yim dua li sim code koj thawj mobile app lossis video game. Tseeb tiag, Arduino tuaj yeem yog txoj hauv kev tsis muaj kev ntxhov siab los ntub koj txhais taw hauv coding.

Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv hloov tus yuam sij zais cia uas siv los xyuas kom meej qhov tsis pub lwm tus paub ntawm cov lus?
Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus? Kev piav qhia: Symmetrical algorithms siv tib tus yuam sij, tus yuam sij zais cia, los encrypt thiab decrypt cov ntaub ntawv. Tus yuam sij no yuav tsum tau muab qhia ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim
Tus tswv tsheb npav thiab tus tswv qhev yog dab tsi?
Thaum ib lub BCLK, ib qho thiab tsuas yog ib qho ntawm cov khoom txuas nrog lub tsheb npav yog tus tswv tsheb npav, txhua yam khoom siv yog ib tug qhev lossis tsis ua haujlwm. Tus tswv tsheb npav pib hloov tsheb npav, thaum tus qhev tsis muaj zog vim nws tsuas tuaj yeem tos qhov kev thov los ntawm tus tswv tsheb npav
Dab tsi yog tus tswv xeev txwv hauv Apex thiab Salesforce?
Per-Transaction Apex Limits Description Synchronous Limit Asynchronous Limit Ntau tshaj plaws ntawm Apex cov hauj lwm ntxiv rau cov kab nrog System.enqueueJob 50 1 Tag nrho cov naj npawb ntawm sendEmail txoj kev tso cai 10 Tag nrho heap loj 4 6 MB 12 MB Lub sij hawm CPU siab kawg ntawm Salesforce servers 5 10,000 milliseconds 60,000 milliseconds
Dab tsi yog qhov txawv ntawm tus tswv tsev raws li kev txheeb xyuas thiab kev nkag mus hauv network?
Qee qhov zoo ntawm hom IDS no yog: Lawv muaj peev xwm txheeb xyuas yog tias qhov kev tawm tsam tau ua tiav lossis tsis ua tiav, thaum lub network raws li IDS tsuas yog muab kev ceeb toom ntawm kev tawm tsam. Lub kaw lus raws li tus tswv tuaj yeem txheeb xyuas cov tsheb khiav tawm kom pom kev tawm tsam kos npe-yog li muab lawv lub peev xwm los saib xyuas cov tsheb khiav encrypted
Cov tswv yim dab tsi suav nrog hauv hnub tim tswv yim hauv html5?
Muaj ob hom tswv yim txhawb rau "datetime" zoo li cov tswv yim. 2. Hom "datetime-local" input type yog tswj hwm hnub tim-thiab-lub sij hawm hauv zos. Kev tswj cov tswv yim nrog "datetime-local" input type sawv cev rau kev tswj hwm uas nws lub ntsiab lus muaj nqis sawv cev rau hnub tim thiab lub sijhawm hauv zos (thiab tsis muaj cov ntaub ntawv teev sijhawm)
