Kodi mungadziwe bwanji ngati khadi lowongolera la LED likugwira ntchito bwino?
Pambuyo pakhadi yowongoleraimayatsidwa, chonde onani kaye nyali yamagetsi.Kuwala kofiira kumasonyeza kuti magetsi a 5V alumikizidwa.Ngati sichiyatsa, chonde zimitsani magetsi a 5V nthawi yomweyo.Onani ngati voteji yogwira ntchito ya 5V yalumikizidwa bwino, ngati pali kuwonjezereka kwamagetsi, kulumikizidwa kobwerera kumbuyo, kulephera, kutulutsa kwafupipafupi, ndi zina zambiri. Chonde gwiritsani ntchito magetsi a 5V kuti mutsegule khadi yowongolera.Ngati kuwala kofiira sikuyatsidwa, kumafunika kukonzedwa.
Njira zonse zothetsera mavuto pazolakwika zamakhadi owongolera a LED
1. Tsimikizirani kuti khadi yowongolera ikugwirizana ndi pulogalamuyo.
2. Onani ngati chingwe cholumikizira ndi chomasuka kapena chomasuka, ndipo tsimikizirani kuti chingwe cholumikizira chikugwiritsidwa ntchito kulumikizakhadi yowongoleraimagwirizana ndi khadi yowongolera.Makhadi ena owongolera amagwiritsa ntchito molunjika (2-2, 3-3, 5-5), pomwe ena amagwiritsa ntchito (2-3, 3-2, 5-5).
3. Onetsetsani kuti hardware dongosolo bwino zoyendetsedwa pa.
4. Sankhani mtundu wolondola wazinthu, njira yotumizira yolondola, nambala yolondola ya doko ndi kuchuluka kwa baud molingana ndi pulogalamu yowongolera khadi ndi khadi yowongolera yomwe mumasankha, ndikuyika bwino adilesi ndi kuchuluka kwa baud pa hardware system molingana ndi Dip switch chithunzi choperekedwa mu pulogalamuyo.
5. Ngati mutayang'ana ndi kukonza zomwe zili pamwambazi, padakali vuto pakutsegula, chonde gwiritsani ntchito multimeter kuti muwone ngati doko lachinsinsi la kompyuta yolumikizidwa kapena hardware system yawonongeka kuti mutsimikizire ngati iyenera kubwezeretsedwa kwa wopanga makompyuta kapena zida zowongolera zoyeserera.
6. Ngati sitepe yachisanu ndi yovuta, chonde funsani wopanga chithandizo chaumisiri.
Zochitika Zodziwika za Kuwonongeka kwa Khadi la Kuwongolera kwa LED
Chodabwitsa 1: Pambuyo polumikizidwa ndikuyatsidwa, mapulogalamu ena okha amasiya kusewera ndikuyambanso kusewera.
Chifukwa chachikulu ndi chakutimagetsindiyosakwanira ndipo khadi yowongolera imayambiranso.1. Chepetsani kuwala;2. Mphamvu yamagetsi yokhala ndi khadi yowongolera imabwera ndi matabwa awiri ochepera;3. Wonjezerani magetsi
Chochitika 2: Khadi lowongolera likakhala labwinobwino, chinsalu chowonetsera sichimawonetsa kapena kuwala kwake sikwachilendo.
Khadi lowongolera litalumikizidwa ndi dalaivala wowonetsa ndikuyatsidwa, zokhazikika ndizojambula 16.Ngati palibe chiwonetsero, chonde onani ngati polarity ya data ndi makonzedwe a OE polarity mu pulogalamu yowongolera ndi zolondola;Ngati kuwalako sikunali kwabwinobwino ndipo pali mzere wowala kwambiri, zikuwonetsa kuti mawonekedwe a OE asinthidwa.Chonde ikani OE molondola.
Chochitika 3: Mukatumiza zidziwitso ku khadi yowongolera, dongosololi limalimbikitsa "Zolakwika zidachitika, kufalitsa kwalephera"
Chonde onani ngati kulumikizana kwa mawonekedwe olankhulirana ndikolondola, ngati jumper pa khadi yowongolera ilumphira pamalo ofananirako, komanso ngati magawo a "Control Card Settings" ndi olondola.Komanso, ngati mphamvu yogwira ntchito ndiyotsika kwambiri, chonde gwiritsani ntchito multimeter kuyeza ndikuwonetsetsa kuti voteji ili pamwamba pa 4.5V.
Chodabwitsa 4: Chidziwitsocho chikatsegulidwa, chinsalu chowonetsera sichikhoza kuwonetsedwa bwino
Chongani ngati jambulani linanena bungwe kusankha mu "Control Khadi Zikhazikiko" ndi olondola.
Chodabwitsa 5: Kulumikizana sikuli bwino panthawi ya 485 maukonde
Chonde onani ngati njira yolumikizirana ndi yolondola.Osalumikiza mizere yolumikizirana ya chinsalu chilichonse pamodzi ndi mawonekedwe apakompyuta molakwika, chifukwa izi zidzatulutsa mafunde amphamvu owoneka bwino ndikusokoneza kwambiri chizindikiro chotumizira.Njira yoyenera yolumikizira iyenera kutsatiridwa, monga momwe zafotokozedwera mu "Communication Interface Usage and Precautions".
Momwe mungathetsere kusokonekera kwa kulumikizana mukamagwiritsa ntchito kutumiza kwa data ya GSM ndi kuyimba kwakutali?
Momwe mungathetsere kusokonekera kwa kulumikizana mukamagwiritsa ntchito kutumiza kwa data ya GSM ndi kuyimba kwakutali?Choyamba, onani ngati pali vuto ndi MODEM.Chotsani MODEM yolumikizidwa ku khadi yowongolera ndikuyilumikiza ku kompyuta ina.Mwanjira iyi, ma MODEM onse otumiza ndi kulandira amalumikizidwa ndi kompyuta ndipo amachotsedwa pamakina owongolera.Tsitsani pulogalamu yotchedwa "Serial Port Debugging Assistant" kuchokera pa intaneti, ndikuigwiritsa ntchito kukhazikitsa ndi kukonza MODEM mukayika.Choyamba, ikani MODEM ya polandirira kuyankha basi.Njira yokhazikitsira ndikutsegula wothandizira serial debugging kumbali zonse ziwiri, ndikulowetsa "ATS0 = 1 Lowani" mu serial debugging wothandizira pamapeto olandila.Lamuloli likhoza kukhazikitsa MODEM ya mapeto olandirira kuyankha basi.Ngati kuyikako kukuyenda bwino, chowunikira cha AA pa MODEM chidzawunikira.Ngati sichinayatse, zoikamo sizikuyenda bwino.Chonde onani ngati kulumikizana pakati pa MODEM ndi kompyuta ndikolondola komanso ngati MODEM imayatsidwa.
Mukatha kuyankha bwino, lowetsani "Nambala Yafoni Yolandila, Lowani" mu serial port debugging wothandizira pamapeto otumiza, ndikuyimba pomaliza.Panthawiyi, zidziwitso zina zitha kutumizidwa kuchokera kumapeto otumizira kupita kumalo olandila, kapena kuchokera kumalo olandila mpaka kumapeto.Ngati zidziwitso zomwe zalandilidwa pa mbali zonse ziwiri ndizabwinobwino, kulumikizana kwakhazikitsidwa, ndipo chowunikira cha CD pa MODEM chimayatsidwa.Ngati zonse zomwe zili pamwambazi ndizabwinobwino, zikuwonetsa kuti kulumikizana kwa MODEM ndikwabwinobwino ndipo palibe mavuto.
Pambuyo poyang'ana MODEM popanda vuto lililonse, ngati kuyankhulana kumatsekedwa, vuto likhoza kukhala chifukwa cha makonzedwe a makadi olamulira.Lumikizani MODEM ku kirediti kadi, tsegulani pulogalamu yokhazikitsira khadi kumapeto kotumiza, dinani Werengani Zikhazikiko Zam'mbuyo, fufuzani ngati serial port baud rate, serial port, protocol, ndi zoikamo zina ndizolondola, kenako dinani Lembani Zikhazikiko mutapanga. kusintha.Tsegulani pulogalamu ya Offline King, ikani mawonekedwe olumikizirana ofananirako ndi magawo munjira yolumikizirana, ndipo pamapeto pake mutumize script.
