Key Takeaways
Zvikamu zvakakosha zveSerial Port
Kunzwisisa zvikamu zve serial port kunotibatsira kuona kuti inoshanda sei uye kuti inoshandiswa sei. Izvo zvinobatanidza uye tambo dzinoshandiswa pakufambisa data ndizvo zvakakosha. Iyo D-subminiature yekubatanidza yakajairika, ine mhando senge DE-9 uye DB-25 kune akasiyana mashandisiro.
Kunzwisisa Serial Connectors
Seri tambo, senge null modem tambo, yakakosha pakukurukurirana kwemudziyo. Vane mapini chaiwo ekutumira uye kutora data. Izvi zvakakosha kuti midziyo itaure kune imwe neimwe.
Kugadzirisa mazinga emagetsi kwakakosha pamhando yedata. Iyo baud rate, kana data kumhanya, inokanganisa mashandisiro anoita zvishandiso pamwe chete. Heino tafura inoratidza mamwe akajairwa serial connectors:
| Connector Type | Pin Count | Common Use Cases | Voltage Levels | Typical Baud Rate |
| D-subminiature (DE-9) | 9 | Vakuru maPC, Serial Devices | -12V kusvika +12V | 300 kusvika 115200 bps |
| DB-25 | 25 | Printers, modem | -12V kusvika +12V | 300 kusvika 115200 bps |
MaSerial Ports Anoshanda Sei?
Chii chinonzi Serial Port Chinoshandiswa?
Serial ports ndiyo yakakosha munzvimbo dzakawanda, kunyanya mumaindasitiri otomatiki uye kupindirana kwemidziyo. Vanobatanidza zvikamu zvakasiyana-siyana zvehardware, zvichiita kuti kutaurirana kuve nyore. Izvi ndezvechokwadi kune ese ekare uye matsva masisitimu, kuve nechokwadi kuti anoshanda nemazvo.
Zvishandiso uye Mamiriro Ekushandisa
Mune zvigadziriso zveindasitiri, serial ports inobatanidza michina kudzora masisitimu. Izvi zvinowedzera kutarisa uye zvinoita kuti mashandiro ashande zvakanaka. Izvo zvakakoshawo pakugadzirisa, kubatsira kutsvaga nekugadzirisa zvikanganiso panguva yekuvandudza.
Kunyangwe masisitimu ekare anoshandisa serial ports, achiratidza kuti tekinoroji iyi inogara kwenguva yakareba sei. Masisitimu akaiswa, seaya ari muGPS anogamuchira, zvakare anovimba nawo. Izvi zvinodaro nekuti ivo vanofanirwa kubatanidza zvishandiso zvakasiyana zvekutevera nzvimbo.
Terminal emulation inoshandisa serial ports kubata system consoles. Izvi zvakakosha pakumhanyisa mirairo uye kutarisa masisitimu ehurongwa. Izvo zvakakosha pakudzora zvishandiso uye kutonga masisitimu zvinobudirira.
Serial Ports mune Yemazuvano Computing
Serial ports inogona kuita sechekare, asi ichiri kukosha nhasi. Zvishandiso zvakawanda, senge USB adapter, zvinoita kuti zvive nyore kuzvishandisa nemasisitimu matsva. Izvi zvinoreva masisitimu ekare uye akawanda maturusi anogona achiri kushandisa serial ports.
Evolution uye Zvinoenderana Nezvazvino
Dzimwe nzvimbo dzakakosha, senge masystem ekudzora, dzichiri kuda serial ports. Iwo ari nyore uye akavimbika. Nzira nyowani dzekubatanidza zvishandiso zvinoita kuti serial ports ishande neazvino tech. Heino tafura inoratidza nei serial ports ichiri kubatsira nhasi.
| Feature | Serial Ports | USB uye Ethernet |
| Nhaka Kuenderana | High | Variable |
| Data Transfer Method | Serial Data Streams | Packet-Yakavakirwa |
| Nzvimbo dzekushandisa | Instrumentation, Kudzora Systems | General Data Transfer |
| Device Support | Zvakajairwa muLegacy Systems | Yakatsigirwa Zvakawanda |
| Kusununguka kweKubatanidza | Inotsamira pane Hardware Abstraction | Kazhinji Nyore |
Kumisikidza uye Kugadzira Serial Port
Kugadzirisa serial port kwakakosha kune zvishandiso zvekutaura kune mumwe nemumwe. Iko kurongeka kwechiteshi kwechiteshi kunoita kuti data rive rakatsinhaniswa zvakanaka. Kutanga, funga kuti ndezvipi marongero aunoda mudziyo wako.| Setting | Tsanangudzo |

Zvishandiso uye Zvishandiso zveSerial Port Kukurukurirana
Kukurukurirana kunobudirira kuburikidza ne serial ports kunoda maturusi ane hunyanzvi uye zvishongedzo. Chishandiso chakakosha ndeye serial breakout box, iyo inobatsira vashandisi kutarisa uye kugadzirisa mazinga echiratidzo panguva yekufambisa data. Ichi chishandiso chakakosha pakuongorora nyaya munguva-chaiyo uye kuve nechokwadi chekuti masaini anosangana nezvinodiwa. Kunzvimbo dzakaoma, a piritsi ine Windows 11 inopa inotakurika mhinduro kune-saiti kugadzirisa dambudziko.
Chinodiwa Midziyo
Munzvimbo dzekuvandudza software, debugger yakakosha pakutsvaga nekugadzirisa zvikanganiso zvehurongwa izvo zvinogona kukanganisa serial kutaurirana. Serial data loggers zvakare akakosha pakubata uye kuongorora dhata hova, ichipa ruzivo rwakakosha mukuita metrics nekufamba kwenguva. Nekuda kwepamusoro-kushanda zvinodiwa, an indasitiri PC ine NVIDIA GPU kana a yakaonda rackmount komputa inogona kutsigira yakadzika data kuongororwa uye kugadzirisa mabasa.
Paunenge uchishanda nemamicrocontrollers uye zvimwe zvishandiso, matambo testers akakosha pakuona kuvimbika uye kushanda kwetambo dzeserial. Kuona masaini masaisai uye kusimbisa mazinga ebaud, oscilloscope yakakosha. Kune yakazara maindasitiri setups, an maindasitiri PC Advantech inopa zvigadziriso zvakavimbika, nepo a mini rugged PC inopa compact uye yakasimba mhinduro. Nezvekutsanangurwa kwegiredhi remauto, funga nezve a kombiyuta yemauto inotengeswa kuwedzera kusimba.
Kunzwisisa iyo Universal Asynchronous Receiver-Transmitter (UART) yakakoshawo pakubata uye kugadzirisa serial kutaurirana zvinobudirira. Chishandiso chega chega chinobatsira mukugadzira iyo yakasimba serial yekutaurirana chimiro, zvichiita kuti kupindirana pakati pemidziyo kuve nyore. Kune mhinduro dzemhando yepamusoro, kuongorora sarudzo kubva kune vanovimbwa vagadziri vemakombuta emaindasitiri inovimbisa kushanda uye kuvimbika.
