Mavuto Omwe Amayambitsa Mavuto ndi Mayankho a Ma module a LED Point Light Sources

M'zaka zaposachedwapa, zoweta malo kuyatsa anayamba mofulumira. Kuunikira kwapanja kokongoletsa malo ndi cholinga chokongoletsa madera akumatauni komanso kutsatsa malonda kumayamikiridwa ndikugwiritsidwa ntchito mochulukira. Itha kugwiritsidwa ntchito kukongoletsa zokongoletsera, ndipo imatha kuphatikizidwa kukhala mizere yowoneka bwino. Koma magwero a kuwala kwa madontho a LED nthawi zonse amakumana ndi zolephera zambiri pakugwiritsa ntchito kwenikweni. Pansipa, ndikuwonetsa zina mwazovuta zomwe wamba komanso mayankho akuwunikira mwatsatanetsatane. Cholakwika 1: Mphamvu ikaperekedwa, kuwala kowongolera (ERROR) kumawunikira, gwero la kuwala sikuli kowala, ndipo palibe kutulutsa kwa makanema ojambula? Yankho: Izi nthawi zambiri zimakhala chifukwa wowongolera samawerenga bwino khadi, ndipo pulogalamu yoyenera yowongolera siyitulutsa. Chifukwa chingakhale: 1.SD khadi alibe kanthu, palibe zotsatira file 2.SD khadi pulogalamu file dzina cholakwika 3.SD khadi khadi 3.SD khadi 3.SD khadi 3.SD khadi 3.SD khadi Mapangidwe monga pakufunika musanakopere fayilo ya zotsatira 4. Fayilo yamphamvu ndi chipangizo cha nyali, chowongolera mu SD khadi sichikugwirizana, muyenera kulumikizana ndi wopanga kuti apangenso fayiloyo 5. Pambuyo posintha khadi latsopano la SD Zoyipa zoyipa: Mphamvu ikaperekedwa, chizindikiro chowongolera ndichabwinobwino, pali kutulutsa kwazizindikiro, koma gawo lowunikira la LED silinasinthe? Yankho: Pamenepa, pamakhala zifukwa zotsatirazi: 1. Yang'anani ngati chizindikiro ndi wolamulira wa nyali zalumikizidwa molondola. 2. Chizindikiro cha nyali chowongolera kunja chili ndi kupita patsogolo / kunja kwa njira, fufuzani ngati chizindikiro chowongolera kuchokera ku siginecha ya nyali yakutsogolo End mu 3. Onani ngati mtunduwo wasankhidwa popanga fayilo mu SD khadi *. LeD inali yogwirizana ndi chip chomwe chimagwiritsidwa ntchito mu nyali zamakono. 4. Nyali ndi chowongolera ziyenera kukhala pamodzi, ndiko kuti, mzere wapansi wa nyaliyo ukhale mzere wapansi. GND imalumikizidwa ndi cholakwika chachitatu: Wowongolera ndi nyali atalumikizidwa, zotsatira zake zimasintha, koma nyali zikuwunikira, ndipo chowongolera chowongolera chikuwonetsa bwino? A: Mzere wapansi pakati pa chowongolera ndi nyali sichilumikizidwa 2. Lantern Mphamvu yamagetsi yochepera 3. Zomwe zili mu SD khadi ndizolakwika. Chipu cha nyali ndi chip cha nyali zenizeni pamene zotsatira zachitika. 4. Mtunda wochokera kwa wowongolera kupita ku nyali yoyamba (mtunda > Mamita a 10), kutumiza kwa chizindikiro kumakhala kosakhazikika Kulephera 4: Mphamvu ikagwiritsidwa ntchito, wolamulira ndi gawo lapitalo la nyali likugwira ntchito bwino. Nyaliyo si yachilendo nyali inayake ikayamba? Yankho: Izi nthawi zambiri zimakhala nyali kuseri kwa nyali zomwe zimalephera kulandira chizindikiro bwino. Zifukwa zake nthawi zambiri zimakhala motere: 1. Nyali za munthu aliyense IC IC kulephera kapena mzere wa chizindikiro umawonongeka isanayambe komanso itatha kuwala. Nyali ikhoza kulembedwa mochepa polemba pulogalamuyo (mwachitsanzo, zidutswa 9,000 zimagwiritsidwa ntchito, ndipo 8,000 zokha ndizolembedwa mu pulogalamuyi). Mwanjira iyi, palibe makanema ojambula pamagawo omaliza. : Pambuyo pa mphamvu, wolamulira amagwira ntchito bwino, nyali ndi yachilendo, ndipo zotsatira za kanema wa kanema ndizosiyana? Yankho: Izi zimachitika chifukwa chosagwirizana ndi dongosolo la kukhazikitsa magetsi ndi mapangidwe. Muyenera kusintha ndondomeko ndi malo a nyali molingana ndi chithunzi chokwera, kapena lowetsani kukonzekera kwa nyali yeniyeni yoyika. Pitani ku kompyuta kuti mukonzekerenso kulephera kwa pulogalamu 6: Mphamvu ikadutsa, gawo lowunikira la LED limatha kusintha bwino, koma pali magwero owunikira omwe amawonetsa mtundu wosiyana ndi wina? Yankho: Izi nthawi zambiri zimachitika chifukwa cha kuwonongeka kwa chip cha R, G, ndi B, zomwe zimapangitsa kuwonetsa kuchepa kwa mtundu. Muyenera kungosintha vutolo ndi mfundo ya kuwala. Yankho la mphambano: 1. Choyamba, tsimikizirani ngati chosinthira choteteza kumbali ya khadi la SD chatsegulidwa. Njira yotsegulira ndi singano yagolide ya SD khadi. 2. Chotchinga chachitetezo chatsegulidwa momwe chikufunikira, koma sichingathe kupanga. Ngati chipangizocho chasweka, chonde sinthani chowerengera cha SD khadi 3. Ngati ntchito yomwe ili pamwambayi ikukanika kuthetsa vuto la masanjidwe, chonde sinthani khadi la SD ndikuyesanso
