●- Deredza kukanganiswa kwezvakatipoteredza: Dzivisa kuisa tambo dzekubatanidza dzeSPI light strip pamwe chete netambo dzemagetsi dzakasimba (220V), nedaro risingasviki 30cm kudzivirira kukanganiswa kwakasimba kwemagetsi kusakanganisa kutapurirana kwechiratidzo; Muzviitiko zvekunze, iva nechokwadi chekuti tambo dzakachengetedzwa zvakanaka kudzivirira kusashanda zvakanaka kwechiratidzo kunokonzerwa nemvura neguruva.
●- Isa michina yekuvandudza masaini: Kana kureba kwetambo imwe chete yeSPI light strip kukadarika mamita mashanu, amplifier yeSPI signal inofanira kuiswa kudzivirira kurasikirwa kwesignali uye kusagadzikana kunokonzerwa nekubuda; kana kureba kwakapfuura mamita gumi, zvinokurudzirwa kupatsanura tambo yemwenje woibatidza kumativi ese, uye panguva imwe chete isa amplifier.
●- Waya dzakajairika: Mitsetse yechiratidzo cheDAT inofanira kusungirirwa yakaparadzana kudzivirira kupindirana nemitsetse yeV+ neGND, nokudaro zvichideredza kupindirana kwemitsetse yechiratidzo; zvinokurudzirwa kusarudza mitsetse yechiratidzo yakavharirwa kuti iwedzere kusimudzira kugona kwekudzivirira kupindirana.

2.5 Danho rechishanu: Kuyedza zvikamu, kuona "nzvimbo yekukanganisa"
●Nzira yekugadzirisa matambudziko muzvikamu: Kamura zvidimbu zvemwenje zveSPI kuita zvikamu zvemamita mashanu chimwe nechimwe, uye batanidza chikamu chimwe nechimwe kune controller kuti zviongororwe. Izvi zvinokurumidza kuona nzvimbo iyo system isiri kudzorwa. Kana chimwe chikamu chisiri kudzorwa, zvinoratidza kuti IC chip yechidimbu chemwenje chechikamu ichocho chakakuvara kana kuti pane kutyoka kwedunhu.
●Nzira yekubata nayo kukuvara: Cheka chikamu chakakuvara, batanidzazve chikamu chisina kukuvadzwa panzvimbo dzakatarwa dzekucheka, chigadzire nechinhu chakakosha chekubatanidza kana welding, teerera matanda akanaka neasina kunaka uye kutevedzana kwewaya; 4-waya SPI light strips (senge WS2815) dzine basa rekutumira nguva dzose panzvimbo dzakapwanyika. Kana girobhu rimwe chete rikakuvara, rinogona kudziviswa pasina kukanganisa mashandiro enguva dzose echikamu chemwenje chinotevera.

III. Kuongororwa Kwemhosva Yakakosha yeSPI Light Strip
Chidimbu chemwenje cheSPI hachidzorwe. Kunze kwezvinetso zvataurwa pamusoro apa, chinonyanya kuenderana ne "machipisi eIC, kutumira kwechiratidzo, uye magadzirirwo emaparameter". Heano zvikanganiso zvakajairika uye mhinduro. Vatangi vanogona kutevedzera zvakananga mirairo yekushanda.

3.1 Zvikanganiso Zvakajairika uye Mhinduro
●- Chikanganiso 1: Chidimbu chemwenje chose hachina kuvhenekerwa, asi mwenje wechiratidzo chemutongi wakajairika → Tarisa kana mutsetse wechiratidzo weDAT wakabatana nenzira isiriyo kana kuti wakasununguka, kana kana terminal yeDIN yakabatana zvisirizvo. Batanidzazve mutsetse wechiratidzo uye iva nechokwadi chekuti divi rewaya rakarurama.
●- Chikanganiso 2: Mwenje inodzima, mavara anokanganiswa, uye hapana kuchinja kunoitika nguva dzose → Tarisa kuti zvinoenderana hereMutongi weSPIuye modhi yeIC yechiedza, kana kuti pangave nekukanganiswa kwechiratidzo; Isa amplifier yechiratidzo, chengetedza mitsetse yechiratidzo kure nematunhu ane voltage yakawanda, uye dzivisa kumonyoroka.
●- Chikanganiso 3: Zvidimbu zvemwenje zvishoma hazvina kuvhenekerwa, asi zvimwe zvese zvakajairika → Chip yeIC yechikamu ichi chemutsetse wemwenje yatsva kana kuti pane break mucircuit. Cheka chikamu chakakuvara, chibatanidze nechinobatanidza chakatsaurirwa, uye teerera kumatanho akanaka neakaipa uye tambo panguva yekusonesa. Kune mamodheru asingapindi mvura, interface inofanira kuvharwazve.
●- Chikanganiso 4: Kutadza kuwana kutonga kwemazinga epixel (sekukundikana kwekuyerera kwemvura uye mhedzisiro yekutevera) → Magadzirirwo eparameter asina kururama emutongi. Gadzirisazve mutongi, sarudza chirongwa chekudzora chemodheru yeIC inoenderana, uye iva nechokwadi chekuti huwandu hwemapikiseli hunoenderana nehurefu chaihwo hwestrip yechiedza.
●- Chikanganiso 5: Kupenya kwezvipenga zvechiedza hakuna kujairika, kunovanda nekudzima → Simba harina kugadzikana kana kuti rakawandisa. Tsiva simba rine simba rakakwana, patsanura zvipenga zvechiedza zvakareba zvakanyanya, uye wedzera mamwe mapoinzi emagetsi.

3.2 Nzira dzekudzivirira pakuongororaChidimbu chemwenje cheSPI
●Dzivisa kukotama zvakanyanya kwezvishandiso zvemwenje kuti waya dzemukati dzisatyoke uye kuti machipisi eIC asadonhe. Radius yekukotama panguva yekuisa haifanirwe kunge iri pasi pe5 cm.
●Kureba kwetambo yega yega yeSPI hakukurudzirwi kudarika mamita gumi. Kana ikapfuura kureba uku, inofanira kupatsanurwa kana kufambiswa nemagetsi kumativi ese, uye amplifier yesignal inofanirawo kuiswa.
●Pakunge paine waya, mutsetse wechiratidzo cheDAT unofanirwa kurongwa wakasiyana kuti usasanganiswe nemitsara yeV+ neGND, nokudaro zvichideredza kukanganiswa kwechiratidzo.
●Kusarudza tambo yemwenje yeSPI ine waya ina (yakadai seWS2815) kunogona kuderedza mukana wekuti "tambo yese isashande zvakanaka nekuda kwekutadza kwegirobhu rimwe chete remwenje", zvichiita kuti ive yakakodzera mamiriro ezvinhu ane zvinodiwa zvakanyanya kuti igare yakasimba.
●Panguva yekupinza, tembiricha haifanirwe kunge yakanyanya kukwira kudzivirira kuti maIC chips asatsve. Nguva yekupinza inofanira kudzorwa mukati memasekonzi maviri kusvika matatu.

Chidimbu chemwenje cheSPI hachidzorwi. Dambudziko guru harisi rekuti "chigadzirwa chakanaka", asi rinokonzerwa nezvinhu zvakaita sekuti "kuisa, kufananidza michina, kutumira masaini", nezvimwewo. Chero bedzi uchitevera pfungwa yekuti "kugadzirisa matambudziko e5-step general, mhinduro dzakanangwa dzematambudziko chaiwo", unogona kukurumidza kuona dambudziko racho. Matambudziko mazhinji anogona kuongororwa ega uye kugadziriswa pasina kudiwa kwevanamakanika vane hunyanzvi.
Kana matanho ekugadzirisa ari pamusoro apa akatadza kugadzirisa dambudziko risingadzoreki, rinogona kunge riri dambudziko remhando yepamusoro nechiedza kana controller pachayo (sekukuvadzwa kwema IC chips, kutadza kushanda kwechirongwa che controller). Muchiitiko ichi, zvinokurudzirwa kubata mainjiniya vane hunyanzvi kuti vaedze kana kutsiva nezvigadzirwa zvinobva kumugadziri ane mukurumbira.
Semunhunyanzvi yekugadzira mwenje we LED, tambo dzedu dzemwenje dzeSPI (dzakadai seWS2811, WS2812B, WS2815, nezvimwewo) dzese dzakaongororwa zvakanyanya uye dzine nhungamiro dzakakwana dzekuisa uye rutsigiro rwehunyanzvi. Kubva pakusarudza chigadzirwa, nhungamiro yekuisa kusvika pakugadzirisa matambudziko, tinopa masevhisi ehunyanzvi mukati menguva yese, tichideredza zvinobudirira matambudziko ekushanda kusingadzoreki panguva yekushandisa uye tichichengetedza chirongwa chako chekushongedza mwenje. Kana ukasangana nematambudziko panguva yekushandisa, unogonatauratimu yedu yehunyanzvi chero nguva kuti tiwane mhinduro dzemunhu mumwe nemumwe.
