UART yog lub npe luv ntawm Universal Asynchronous Receiver Transmitter, lub npe ntawm lub nti uas ua rau lub computer sib txuas lus ntawm kab serial kab kab COM (chaw nres nkoj sib txuas lus) yog thawj, tseem muaj ntau, lub npe ntawm qhov chaw nres nkoj serial interface ntawm PC-compatible computers. Nws tuaj yeem xa mus tsis yog rau cov chaw nres nkoj lub cev nkaus xwb, tab sis kuj rau cov chaw nres nkoj emulated, xws li cov chaw nres nkoj tsim los ntawm Bluetooth lossis USB adapters. https://en.wikipedia.org › wiki › COM_(hardware_interface)

Ntawm qhov tso zis ntawm UART cov khoom no feem ntau yog sawv cev los ntawm qib logic voltages. Cov khoom no tuaj yeem dhau los ua RS-232, RS-422, RS-485, lossis tej zaum qee qhov tshwj xeeb tshwj xeeb.
UART puas siv RS232?
UART yog kho vajtse transceiver uas siv qee cov txheej txheem qhia. A UART tuaj yeem siv RS232 , tab sisnws can kuj siv lwm yam serial raws tu qauv, xws li RS485, TTL uas txhais cov qib sib txawv voltage thiab lwm yam los ntawm cov txhais los ntawm RS232.
Yog Arduino serial UART?
Tag nrho Arduino boards muaj tsawg kawg ib qhov chaw nres nkoj(tseem hu ua UART lossis USART): Serial. Nws sib txuas lus ntawm tus pins 0 (RX) thiab 1 (TX) nrog rau lub computer ntawm USB. Yog li, yog tias koj siv cov haujlwm no, koj tsis tuaj yeem siv tus pins 0 thiab 1 rau cov tswv yim lossis cov zis tawm.
