Iyo UART protocol inoshanda sei? Kana wakambozvibvunza kuti midziyo yemagetsi inogona kutaurirana sei? zvinobudirira uye nekukurumidza, mhinduro inowanikwa muUART protocol. Iyi protocol, ipfupi kune Universal Asynchronous Receiver/Transmitter, yakakosha mumunda wemagetsi uye hurongwa. Inoshanda senge yekutaurirana interface inobvumira kuchinjanisa data pakati pezvishandiso zvakasiyana, senge microcontrollers uye peripherals. Kuburikidza netambo dzakareruka dzetambo, masaini anofambiswa uye anogamuchirwa nenzira yemabhiti, ayo anobvumira kuendeswa kweruzivo serially. Muchikamu chino, tichaongorora zvakajeka kuti iyi protocol inoshanda sei, kuitira kuti iwe unzwisise zviri nani kuti kutaurirana pakati pezvigadzirwa zvemagetsi zvakasiyana kunoitika sei.

Nhanho nhanho ➡️ Iyo UART protocol inoshanda sei?

Iyo UART protocol inoshandiswa zvakanyanya kune serial kutaurirana. pakati pemidziyo zvemagetsi. Inobvumira kuendeswa kwebhinari data nenzira iri nyore uye inoshanda. Zvadaro, tinotsanangura kuti iyi protocol inoshanda sei nhanho nhanho:

• Danho rekutanga: Kutanga kutaurirana. Kuti zvishandiso zviviri kutaurirana kuburikidza neUART protocol, mumwe wavo anofanira kutora chinzvimbo chatenzi uye mumwe semuranda. Tenzi anotanga kutaurirana nekutumira chiratidzo chekutanga chinozivikanwa sekutanga zvishoma.
• Danho rekutanga: Data transfer. Kana iyo yekutanga bits yatumirwa, tenzi anotanga kutumira data bits rimwe nerimwe. Chidimbu chimwe nechimwe chinofambiswa seri, ndiko kuti, chimwe mushure mechimwe.
• Danho rekutanga: Data bits. Imwe neimwe diki yedata inotumirwa mukurongeka kwediki kune yakanyanya kukosha. Semuenzaniso, kana tiri kutumira nhamba 5, iyo mubhinari inoti 0101, iyo isinganyanyi kukosha (1) ichatanga kutumirwa, ichiteverwa neinotevera bit (0), zvichingodaro kusvika mana mabhiti apera.
• Danho rekutanga: Parity (optional). Mune zvimwe zviitiko, parity bit inogona kuwedzerwa kuratidza kutendeseka kweiyo data inofambiswa. Ichi chidimbu chinoverengerwa zvichienderana nehuwandu hwemamwe ari mu data bits uye chinoshandiswa kuona zvikanganiso zvinogona kuitika panguva yekufambisa.
• Danho rekutanga: Stop bit(s). Kana mabhiti e data achinge atumirwa, tenzi anotumira imwe kana anopfuura mabheti ekumira kuratidza kupera kwekutapurirana. Aya mabhiti kazhinji ane kukosha kunonzwisisika 1.
• Danho rekutanga: Kupera kwekukurukurirana. Mushure mekutumira mabheti ekumira, kutaurirana kunoonekwa sekwakazara uye zvishandiso zvinodzokera kune yavo yekurara.

Iyo UART protocol inoshandiswa zvakanyanya mumidziyo yakadai semamicrocontrollers, mamodule ekutaurirana uye zvimwe zvinhu zvemagetsi. Kureruka kwayo uye kushanda zvakanaka kunoita kuti ive sarudzo inoyevedza yekutaurirana pakati pemidziyo. Iye zvino zvaunoziva kuti inoshanda sei, unogona kuishandisa! mumapurojekiti ako zvemagetsi!

UART Protocol FAQ

1. Chii chinonzi UART protocol?

Iyo UART (Universal Asynchronous Receiver/Transmitter) protocol ndeye serial yekutaurirana chiyero chinoshandiswa kufambisa data pakati pemidziyo yemagetsi.

2. Chii chinonzi UART kutaurirana?

Kukurukurirana kweUART kunosanganisira kutumira uye kugamuchira data muchimiro chemapaketi emabhiti pamusoro petambo yekutapurirana, pasina chiratidzo chewachi yakagovaniswa.

3. Kukurukurirana kweUART kunotangwa sei pakati pemidziyo?

Kukurukurirana kweUART kunotangwa kuburikidza nekubatana kwemuviri uchishandisa mapini maviri: imwe kutumira data (TX) uye imwe kuigamuchira (RX).

4. Chii chinonzi kumhanya kwekufambisa muUART?

Iyo yekumhanyisa yekufambisa, inozivikanwawo sebaudrate, inosarudza huwandu hwemabheti anotumirwa kana kugamuchirwa pasekondi. Inogadziriswa uye inogona kusiyana zvichienderana nemidziyo.

5. Maitiro ekugadzirisa chiyero chebaud muUART?

1. Tanga serial port configuration.
2. Taura kasi yaunoda kutapurirana.
3. Isa iyo gadziriso kune serial port.

6. Ndeupi rudzi rweprotocol inonzi UART?

UART is asynchronous protocol, zvinoreva kuti haishandise chiratidzo chewachi yakagovaniswa pakati pemidziyo yekutaurirana.

7. Ndeupi musiyano uripo pakati peUART neRS232?

UART iprotocol yekutaurirana, nepo RS232 iri chimiro chemuviri chinoshandisa iyo UART protocol kuendesa serial data.

8. Ndezvipi zvinogumira pakutaurirana kweUART?

1. Kutaurirana kweUART kunongobvumira kubatana pakati pemidziyo miviri.
2. Kutumira kunoitika mukati Nzira imwe zvose (full-duplex haigoneki).
3. Pane chinhambwe chinogumira nekuda kwekurasikirwa kwechiratidzo kuburikidza netambo.

9. Chii chakanakira kushandisa UART?

Kubatsira kwekushandisa UART ndeyekureruka kwayo uye kwese kwese, sezvo iripo mumhando dzakasiyana dzemidziyo yemagetsi.
