Hom kev sib txuas lus serial no qee zaum hu ua TTL serial (transistor-transistor logic). Serial kev sib txuas lus ntawm a TTL theem yuav ib txwm nyob nruab nrab ntawm qhov txwv ntawm 0V thiab Vcc, uas feem ntau yog 5V lossis 3.3V. Alogic siab ('1') yog sawv cev los ntawm Vcc, thaum lub logic qis ('0') yog 0V.
Ib yam li ntawd, nws tau nug, qhov chaw nres nkoj TTL yog dab tsi?
A TTL Teeb liab yog ib hom kev kho vajtse interface qauv raws li cov khoom hluav taws xob ntawm TTL (Transistor-Transistor Logic). Rau ib TTL input qhov no txhais tau hais tias txhua yam hauv qab no 0.8 volts yog "zero" thiab txhua yam saum toj no 2.4 volts yog "ib qho," thiab hais tias nws nthuav tawm qhov load tsawg dua 1.6ma rau lub voj voog tsav tsheb.
Dab tsi yog qhov txawv ntawm TTL thiab rs232? Cov TTL interface twb tsawg polarity txawv yog tias lub teeb liab poob tsuas yog 2 volts. Txawm tias cov TSI RS232 txheem txhais TSI RS232 los ua ib tug tseeb TSI RS232 interface, thiab TTL yeej tsis ua raws li cov TSI RS232 standard, nyob rau hauv kev xyaum feem ntau ntawm cov TSI RS232 serial ports peb txuas scanners rau yog TTL chaw nres nkoj.
Cov lus nug tseem yog, TTL UART yog dab tsi?
UART = Universal AsynchronousReceiver/Transmitter. Nws yog lub hauv paus nti (los yog virtual muaj nuj nqi hauv microcontroller) uas encodes cov ntaub ntawv cov khoom serially rau hauv astandard hom ntawv nrog ib tug pib me ntsis, nres me ntsis (s), ceev, thiab lwm yam. TTLUART yuav tso zis (thiab input) nkaus xwb TTL theem, qhov tseem ceeb 0 ntsis = 0V thiab 1 ntsis = 5V.
Dab tsi yog kev siv serial pib 9600 hauv Arduino?
Raws li lub npe qhia, xwm txheej . pib ( 9600 ) yog ib lo lus txib uas koj muab rau koj Arduino rau pib serial kev sib txuas lus. Kuv massuming koj yog ib tug beginner. Txawm li cas los xij, raws li koj tuaj yeem pom ntawm IDE, muaj ib qho xwm txheej saib xyuas. Nws outputs cov ntaub ntawv uas koj configure nws mus tso zis.

W3c yog dab tsi Whatwg yog dab tsi?
Lub Web Hypertext Application Technology Working Group (WHATWG) yog ib lub zej zog ntawm cov neeg nyiam hloov kho HTML thiab lwm yam technologies. WHATWG tau tsim los ntawm cov tib neeg los ntawm Apple Inc., Mozilla Foundation thiab Opera Software, ua tus neeg muag khoom Web browser, hauv 2004
Cell referencing yog dab tsi thiab dab tsi yog qhov sib txawv ntawm kev xa tawm?
Muaj ob hom kev siv ntawm tes: txheeb ze thiab tsis meej. Cov txheeb ze thiab cov ntawv pov thawj tseeb coj txawv txawv thaum theej thiab sau rau lwm lub hlwb.Cov ntaub ntawv txheeb ze hloov thaum tus qauv raug theej rau lwm lub xovtooj. Cov ntaub ntawv tseeb, ntawm qhov tod tes, tseem nyob tas li txawm tias lawv tau theej qhov twg
Social engineering yog dab tsi thiab nws lub hom phiaj yog dab tsi?
Social engineering yog lo lus siv rau ntau yam kev ua phem ua phem uas ua tiav los ntawm tib neeg kev sib cuam tshuam. Nws siv kev puas siab puas ntsws los ntxias cov neeg siv kom ua yuam kev kev ruaj ntseg lossis muab cov ntaub ntawv rhiab
Dab tsi yog tus sawv cev heuristic Dab tsi yog qhov muaj heuristic?
Qhov muaj heuristic yog ib txoj kev puas siab puas ntsws uas pab peb txiav txim siab raws li nws yooj yim npaum li cas los coj ib yam dab tsi rau hauv siab. Tus neeg sawv cev heuristic yog ib txoj kev puas siab puas ntsws uas pab peb txiav txim siab los ntawm kev sib piv cov ntaub ntawv rau peb cov qauv kev puas hlwb
Dab tsi yog qhov txawv ntawm CMOS thiab TTL cov tsev neeg logic?
CMOS thiab TTL yog ob qho kev faib tawm ntawm kev sib xyaw ua ke. CMOS sawv cev rau 'Complementary MetalOxide Semiconductor', thaum TTL txhais tau tias 'Transistor-TransistorLogic'. Lub sij hawm TTL tau txais los ntawm kev siv ob BJTs (Bipolar Junction Transistors) hauv kev tsim txhua lub rooj vag
