Indlela yokunquma ukuthi ikhadi lokulawula i-LED lisesimweni esivamile sokusebenza?
Ngemva kweikhadi lokulawulaivuliwe, sicela ubheke ukukhanya kwenkomba yamandla kuqala.Isibani esibomvu sibonisa ukuthi i-voltage engu-5V ixhunyiwe.Uma ingakhanyi, sicela ucishe ugesi we-5V ngokushesha.Hlola ukuthi ingabe i-voltage yokusebenza engu-5V ixhumeke kahle yini, noma kukhona ukugcwala ngokweqile, ukuxhunywa okubuyela emuva, ukwehluleka, isifunda esifushane esiphumayo, njll. Sicela usebenzise ugesi ohlukile ongu-5V ukuze unike amandla ikhadi lokulawula.Uma ilambu elibomvu lingakhanyi, lidinga ukulungiswa.
Izinyathelo ezijwayelekile zokuxazulula izinkinga zamaphutha ekhadi lokulawula le-LED
1. Qinisekisa ukuthi ikhadi lokulawula liyahambisana nesofthiwe.
2. Hlola ukuthi ikhebula lokuxhuma lixega noma lixega, bese uqinisekisa ukuthi ikhebula le-serial elisetshenzisiwe ukuxhumaikhadi lokulawulaiyahambisana nekhadi lokulawula.Amanye amakhadi okulawula asebenzisa i-straight through (2-2, 3-3, 5-5), kanti amanye asebenzisa (2-3, 3-2, 5-5).
3. Qinisekisa ukuthi ihadiwe yesistimu yokulawula ivulwe ngendlela efanele.
4. Khetha imodeli yomkhiqizo efanele, imodi yokudlulisa efanele, inombolo ye-serial port efanele kanye nezinga elilungile le-baud ngokusho kwesofthiwe yekhadi lokulawula kanye nekhadi lokulawula olikhethayo, bese usetha ngendlela efanele inombolo yekheli kanye ne-baud ku-hardware yesistimu yokulawula ngokusho Dip switch diagram ehlinzekwe ku-software.
5. Uma ngemva kokuhlola nokulungiswa okungenhla, kusenenkinga ngokulayisha, sicela usebenzise i-multimeter ukukala ukuthi ingabe i-serial port yekhompyutha exhunyiwe noma i-hardware yesistimu yokulawula yonakele ukuze uqinisekise ukuthi kufanele ibuyiselwe kumkhiqizi wekhompyutha noma. i-hardware yesistimu yokulawula ukuze ihlolwe.
6. Uma isinyathelo sesihlanu singalungile, sicela uxhumane nomkhiqizi ukuze uthole ukwesekwa kobuchwepheshe.
Ukwenzeka Okujwayelekile Kokungasebenzi Kwekhadi Lokulawula I-LED
Umkhuba 1: Ngemva kokuxhunywa futhi kuvulwe, ezinye izinhlelo zizoyeka ukudlala futhi ziqale ukudlala futhi.
Isizathu esikhulu ukuthi iukunikezwa kwamandla kagesiayanele futhi ikhadi lokulawula liziqalela kabusha.1. Yehlisa ukukhanya;2. Ukunikezwa kwamandla ngekhadi lokulawula kuza namabhodi amayunithi amabili amancane;3. Khulisa ukunikezwa kwamandla
I-Phenomenon 2: Uma ikhadi lokulawula livamile, isikrini sokubonisa asibonisi noma ukukhanya kungavamile
Ngemuva kokuthi ikhadi lokulawula lixhunywe kumshayeli wesibonisi futhi livuliwe, okuzenzakalelayo amaskena ayi-16.Uma singekho isibonisi, sicela uhlole ukuthi i-data polarity kanye nezilungiselelo ze-OE polarity kusofthiwe yokulawula zilungile yini;Uma ukukhanya kungavamile futhi kunomugqa ogqamile ngokukhethekile, kubonisa ukuthi ukulungiselelwa kwe-OE kuhlehlisiwe.Sicela usethe i-OE ngendlela efanele.
I-Phenomenon 3: Lapho udlulisela imininingwane ekhadini lokulawula, uhlelo lukhuthaza ukuthi "Kwenzeke iphutha, ukudluliswa kwehlulekile"
Sicela uhlole ukuthi uxhumano lwesixhumi esibonakalayo silungile yini, ukuthi i-jumper esekhadini lokulawula igxuma endaweni ehambisanayo yeleveli, nokuthi amapharamitha kokuthi "Izilungiselelo Zekhadi Lokulawula" alungile yini.Futhi, uma i-voltage yokusebenza iphansi kakhulu, sicela usebenzise i-multimeter ukuze ulinganise futhi uqinisekise ukuthi i-voltage ingaphezu kuka-4.5V.
Umcimbi 4: Ngemva kokuba ulwazi selulayishiwe, isikrini sokubonisa asikwazi ukuboniswa ngendlela evamile
Hlola ukuthi ukukhetha okuphumayo kokuskena kokuthi "Izilungiselelo Zekhadi Lokulawula" kulungile yini.
Umkhuba 5: Ukuxhumana akusheleli ngesikhathi sokuxhumana kwe-485
Sicela uhlole ukuthi indlela yokuxhuma yolayini wokuxhumana ilungile yini.Ungayixhumi imigqa yokuxhumana yesikrini ngasinye ndawonye kusixhumi esibonakalayo sekhompyutha ngephutha, njengoba lokhu kuzokhiqiza amagagasi anamandla abonisiwe futhi kubangele ukuphazamiseka okukhulu kusiginali yokudlulisela.Indlela yokuxhumana efanele kufanele yamukelwe, njengoba kuchaziwe kokuthi "Ukusetshenziswa Nezinyathelo Zokuqapha Zesixhumi Sezokuxhumana".
Ungakuxazulula kanjani ukuminyana kokuxhumana lapho usebenzisa ukudluliswa kwedatha ye-GSM nokudayela ukude?
Ungakuxazulula kanjani ukuminyana kokuxhumana lapho usebenzisa ukudluliswa kwedatha ye-GSM nokudayela ukude?Okokuqala, hlola ukuthi ingabe kukhona inkinga nge-MODEM.Nqamula i-MODEM exhunywe ekhadini lokulawula bese uyixhuma kwenye ikhompuyutha.Ngale ndlela, kokubili ukuthumela nokwamukela ama-MODEM axhunywe kukhompuyutha futhi anqanyuliwe ohlelweni lokulawula.Landa isofthiwe ebizwa ngokuthi "I-Serial Port Debugging Assistant" kusukela ku-inthanethi, futhi uyisebenzisele ukusetha nokulungisa i-MODEM ngemva kokufaka.Okokuqala, setha i-MODEM yesiphetho sokwamukela ekuphenduleni okuzenzakalelayo.Indlela yokusetha iwukuvula isilekeleli sokulungisa iphutha kuzo zombili iziphetho, bese ufaka okuthi "ATS0=1 Enter" kusilekeleli sokususa iphutha se-serial yesiphetho sokwamukela.Lo myalo ungasetha i-MODEM yesiphetho sokwamukela ibe impendulo ezenzakalelayo.Uma isilungiselelo siphumelele, ukukhanya kwenkomba ye-AA kuMODEM kuzokhanya.Uma ingakhanyi, isilungiselelo asiphumeleli.Sicela uhlole ukuthi ukuxhumana phakathi kwe-MODEM nekhompyutha kulungile yini nokuthi i-MODEM ivuliwe yini.
Ngemuva kokuthi ukulungiselelwa kokuphendula okuzenzakalelayo kube yimpumelelo, faka "Inombolo Yocingo Yomamukeli, Faka" kusilekeleli sokulungisa iphutha sembobo ekupheleni kokuthumela, bese udayela indawo yokwamukela.Ngalesi sikhathi, olunye ulwazi lungadluliselwa kusuka ekugcineni kokuthumela kuya ekugcineni kokwamukela, noma ukusuka ekugcineni kuya ekugcineni kokuthumela.Uma ulwazi olutholwe kuzo zombili iziphetho luvamile, uxhumano selusunguliwe, kanye nesibani se-CD esiku-MODEM sivuliwe.Uma zonke lezi zinqubo ezingenhla zivamile, kubonisa ukuthi ukuxhumana kwe-MODEM kuyinto evamile futhi azikho izinkinga.
Ngemva kokuhlola i-MODEM ngaphandle kwezinkinga, uma ukuxhumana kusavinjiwe, inkinga ingase ibe ngenxa yezilungiselelo zekhadi lokulawula.Xhuma i-MODEM ekhadini lokulawula, vula isofthiwe yezilungiselelo zekhadi lokulawula ekupheleni kokuthumela, chofoza okuthi Funda Izilungiselelo Emuva, hlola ukuthi isilinganiso se-serial port baud, i-serial port, iphrothokholi, nezinye izilungiselelo zilungile, bese uchofoza okuthi Bhala Izilungiselelo ngemva kokwenza. izinguquko.Vula isofthiwe ye-Offline King, setha ukuxhumana okuhambisanayo namapharamitha kumodi yokuxhumana, bese ekugcineni udlulise umbhalo.
