Indlela yokufumanisa ukuba ikhadi lokulawula i-LED likwimeko yokusebenza eqhelekileyo?
Emva kweikhadi lokulawulailayitiwe, nceda ujonge isibane sombane kuqala.Isibane esibomvu sibonisa ukuba i-voltage ye-5V ixhunyiwe.Ukuba ayikhanyi, nceda ucime ngoko nangoko umbane we-5V.Khangela ukuba i-voltage esebenzayo ye-5V iqhagamshelwe ngokufanelekileyo, ingaba kukho umbane ogqithisiweyo, uqhagamshelo olubuyela umva, ukungaphumeleli, ukuphuma kwesiphaluka esifutshane, njl.Ukuba isibane esibomvu asikhanyisi, kufuneka silungiswe.
Amanyathelo okusombulula iingxaki ngokubanzi kwiimpazamo zekhadi lolawulo lwe-LED
1. Qinisekisa ukuba ikhadi lokulawula liyahambelana nesofthiwe.
2. Khangela ukuba intambo yokuqhagamshela ikhululekile okanye ikhululekile, kwaye uqinisekise ukuba intambo yesiriyali isetyenziselwe ukuqhagamshela intambo.ikhadi lokulawulaiyahambelana nekhadi lokulawula.Amanye amakhadi okulawula asebenzisa ngokuthe ngqo (2-2, 3-3, 5-5), ngelixa abanye basebenzisa (2-3, 3-2, 5-5).
3. Qinisekisa ukuba i-hardware yesistim yolawulo inikwe amandla ngokufanelekileyo.
4. Khetha imodeli yemveliso echanekileyo, imowudi yothumelo echanekileyo, inombolo ye-serial port echanekileyo kunye nesantya esichanekileyo se-baud ngokwesoftware yekhadi lokulawula kunye nekhadi lokulawula olikhethayo, kwaye usete ngokuchanekileyo idilesi yebit kunye nereyithi yebhaud kwi-hardware yesistim yolawulo ngokwe- Dip switch diagram enikwe kwisoftware.
5. Ukuba emva kokutshekishwa kunye nezilungiso zingentla, kusekho ingxaki ekulayisheni, nceda usebenzise i-multimeter ukulinganisa ukuba i-serial port yekhompyutheni edibeneyo okanye i-hardware yesistim yokulawula yonakalisiwe ukuqinisekisa ukuba kufuneka ibuyiselwe kumenzi wekhompyutha okanye i-hardware yenkqubo yolawulo yokuvavanya.
6. Ukuba isinyathelo sesihlanu singathandeki, nceda uqhagamshelane nomenzi wenkxaso yobugcisa.
I-Phenomena eqhelekileyo ye-LED yoLawulo lweKhadi engasebenzi kakuhle
I-Phnomenon 1: Emva kokuqhagamshelwa kwaye inikwe amandla, kuphela ezinye iinkqubo ziya kuyeka ukudlala kwaye ziqale ukudlala kwakhona.
Esona sizathu sikukuba iukunikezwa Amandlaayonelanga kwaye ikhadi lolawulo liziqalela kwakhona.1. Nciphisa ukukhanya;2. Ukunikezelwa kwamandla kunye nekhadi lokulawula liza kunye neebhodi zeeyunithi ezimbini ezincinci;3. Ukwandisa ukunikezelwa kwamandla
I-Phnomenon 2: Xa ikhadi lokulawula liqhelekile, isikrini sokubonisa asibonisi okanye ukukhanya akuqhelekanga.
Emva kokuba ikhadi lokulawula liqhagamshelwe kumqhubi wesiboniso kwaye linikwe amandla, ukungagqibekanga kukuhlolwa kwe-16.Ukuba akukho mboniso, nceda ujonge ukuba idata polarity kunye neOE polarity useto kwisoftware yolawulo ichanekile;Ukuba ukuqaqamba akuqhelekanga kwaye kukho umgca oqaqambe ngokukodwa, oko kubonisa ukuba useto lwe-OE lubuyisiwe.Nceda usete i-OE ngokuchanekileyo.
I-Phnomenon 3: Xa uhambisa ulwazi kwikhadi lokulawula, inkqubo ikhuthaza "Impazamo yenzekile, ukuhanjiswa kwahluleka"
Nceda ujonge ukuba unxibelelwano lwe-interface yonxibelelwano luchanekile, nokuba i-jumper kwikhadi lolawulo itsiba kwinqanaba elihambelanayo, nokuba iiparamitha kwi "Izicwangciso zeKhadi lokulawula" zichanekile.Kwakhona, ukuba i-voltage esebenzayo iphantsi kakhulu, nceda usebenzise i-multimeter ukulinganisa kwaye uqinisekise ukuba i-voltage ingaphezulu kwe-4.5V.
I-Phnomenon 4: Emva kokuba ulwazi lulayishiwe, isikrini sokubonisa asikwazi ukubonisa ngokuqhelekileyo
Khangela ukuba ukhetho lwemveliso yokuskena kwi "Izicwangciso zeKhadi lokulawula" luchanekile.
I-Phnomenon 5: Unxibelelwano alugudi ngexesha lothungelwano lwe-485
Nceda khangela ukuba indlela yoqhagamshelwano yomgca wonxibelelwano ichanekile.Musa ukudibanisa imigca yonxibelelwano yesikrini ngasinye kunye nojongano lwekhompyuter ngempazamo, njengoko oku kuya kuvelisa amaza abonakalisiweyo anamandla kwaye kubangele ukuphazamiseka okukhulu kwisiginali yothumelo.Indlela yoqhagamshelo echanekileyo kufuneka yamkelwe, njengoko icacisiwe kwi-"Communication Interface Usage and Precautions".
Ukusombulula njani ukuxinana konxibelelwano xa usebenzisa ukuhanjiswa kwedatha ye-GSM kunye nokudayela kude?
Ukusombulula njani ukuxinana konxibelelwano xa usebenzisa ukuhanjiswa kwedatha ye-GSM kunye nokudayela kude?Okokuqala, khangela ukuba kukho ingxaki ngeMODEM.Nqamula iMODEM eqhagamshelwe kwikhadi lolawulo kwaye uyiqhagamshele kwenye ikhompyuter.Ngale ndlela, zombini ukuthumela nokufumana iiMODEM ziqhagamshelwe kwikhompyuter kwaye zikhutshiwe kwinkqubo yolawulo.Khuphela isoftwe ebizwa ngokuba yi "Serial Port Debugging Assistant" kwi-intanethi, kwaye uyisebenzisele ukuseta kunye nokucoca iMODEM emva kofakelo.Okokuqala, seta iMODEM yesiphelo sokufumana impendulo ezenzekelayo.Indlela yokumisela kukuvula i-serial debugging umncedisi kuzo zombini iziphelo, kwaye ufake "ATS0=1 Ngena" kwi-serial debugging umncedisi wesiphelo sokufumana.Lo myalelo unokuseta iMODE yesiphelo sokufumana impendulo ezenzekelayo.Ukuba useto luphumelele, ukukhanya kwe-AA kwi-MODEM kuya kukhanya.Ukuba ayikhanyiswanga, useto aluphumelelanga.Nceda ujonge ukuba udibaniso phakathi kweMODEM kunye nekhompyuter luchanekile na kwaye ukuba iMODEM iyasebenza.
Emva kokuba ummiselo wokuphendula ngokuzenzekelayo uphumelele, faka "Inombolo yefowuni yoMmkeli, Ngena" kwi-serial port debugging umncedisi ekupheleni kokuthumela, kwaye ucofe isiphelo sokufumana.Ngeli xesha, olunye ulwazi lunokudluliselwa ukusuka ekupheleni kokuthumela ukuya ekupheleni kokufumana, okanye ukusuka ekupheleni kokufumana ukuya ekupheleni kokuthumela.Ukuba ulwazi olufunyenwe kuzo zombini iziphelo luqhelekile, uqhagamshelo lonxibelelwano lusekiwe, kunye nesibane sesalathisi seCD kwiMODEM sivuliwe.Ukuba zonke ezi nkqubo zingentla ziqhelekile, kubonisa ukuba unxibelelwano lweMODEM luqhelekile kwaye akukho ngxaki.
Emva kokujonga iMODEM ngaphandle kwemiba, ukuba unxibelelwano lusavaliwe, ingxaki ingaba ngenxa yezicwangciso zekhadi lokulawula.Qhagamshela iMODEM kwikhadi lolawulo, vula iisetingi zekhadi lolawulo ekupheleni kokuthumela, nqakraza Funda Umva Useto, khangela ukuba i-serial port baud rate, i-serial port, iprotocol, kunye nezinye izicwangciso zichanekile, uze ucofe uBhala Useto emva kokwenza. utshintsho.Vula i-software ye-Offline King, setha i-interface yonxibelelwano ehambelanayo kunye neeparitha kwimodi yonxibelelwano, kwaye ekugqibeleni uthumele iskripthi.
