Ib tug ua tiav RS-232 interface yuav feem ntau koom nrog UART thiab RS-232 qib hloov pauv. Tsis tas li ntawd, tus qauv RS-232 suav nrog cov ntsiab lus ntawm ob peb lwm cov cim qhia tus pin ntxiv rau TX thiab RX, uas koj yuav xav tau siv nyob ntawm cov cuab yeej koj xav tau txuas rau.
UART hom twg yog RS232?
cmartinez. UART yog kev sib txuas lus raws tu qauv, thaum RS232 txhais cov theem teeb liab ntawm lub cev. Ntawd yog, thaum UART muaj txhua yam ua nrog cov logic thiab programming, nws tsis muaj dab tsi ua rau cov khoom siv hluav taws xob ib leeg. Txawm hais tias RS232 hais txog cov khoom siv hluav taws xob thiab khoom siv uas xav tau rau kev sib txuas lus serial.
Yog RS232 Kev Kub Ceev UART?
Piv nrog cov kev sib txuas tom qab xws li RS-422, RS-485 thiab Ethernet, RS-232 muaj qis dua kis ceev, luv dua qhov ntev tshaj plaws, qhov hluav taws xob loj dua viav vias, tus qauv loj dua connectors, tsis muaj peev xwm multipoint thiab txwv multidrop muaj peev xwm.
Yog UART ib TTL lossis RS232?
Tab sis "UART" tsuas yog ib feem ntawm qhov "RS-232" yog. RS-232 ntxiv cov txiaj ntsig qub txeeg qub teg rau qhov txiaj ntsig binary (0/1 lossis hi/lo, lossis "kos" thiab "chaw" hauv RS-232 tham). Ib TTL UART yuav tso zis (thiab cov tswv yim) tsuas yog TTL qib, qhov tseem ceeb 0 ntsis=0V thiab 1 ntsis=5V.
Puas yog qhov chaw nres nkoj ntawm UART?
Hom kev ua haujlwm no tau raug xa mus los ntawm ntau lub npe sib txawv: Serial Port, RS-232 Interface, COM Port, tab sis lub npe tseeb yog qhov tseebUART (Universal Asynchronous Receiver Transmitter). UART yog ib txoj hauv kev yooj yim tshaj plaws los tham nrog koj FPGA.

Excel puas tuaj yeem siv ntau tus neeg siv?
Yog tias koj xav kom ntau tus neeg siv ua haujlwm hauv tib phau ntawv ua haujlwm Excel ib txhij, koj tuaj yeem khaws phau ntawv ua haujlwm ua phau ntawv qhia ua haujlwm. Cov neeg siv tuaj yeem nkag mus rau cov ntaub ntawv, ntxig kab thiab kab, ntxiv thiab hloov cov qauv, thiab hloov formatting.
Puas yog kev siv hluav taws xob siv hluav taws xob?
Usability engineering yog kev qhuab qhia uas tsom mus rau kev txhim kho kev siv tau ntawm kev sib tham sib. Nws rub tawm cov kev xav los ntawm kev tshawb fawb hauv computer thiab kev puas siab puas ntsws los txhais cov teeb meem uas tshwm sim thaum siv cov kab ke.
Puas siv hluav taws xob hauv qhov hluav taws xob tuaj yeem siv rau ntawm qhov loj?
Txawm hais tias tsawg dua, lwm hom kev siv hluav taws xob hauv av tuaj yeem siv los muab ntau lub zog ntau dua. Tapping qhov chaw ntawm cov dej kub faus rau hauv qab lub ntiaj teb saum npoo tuaj yeem muab cua sov rau cov neeg coob coob, thiab tsim kom muaj zog txaus los tsim hluav taws xob loj.
Puas siv cov kab laum terro tuaj yeem siv sab nraud?
TERRO ® Sab nraum zoov Cov Kua Dej Tsaws Tsaws tuaj ua ntej puv thiab npaj-rau-siv. Tsuas tso cov ceg txheem ntseeg nyob rau hauv qhov chaw sab nraum zoovqhov chaw koj pom cov kab ntsaum, tawg tawm ntawm qhov qhib tab, thiab cia cov kab nuv ntses ua haujlwm nws cov khawv koob.
