Kunanirwa kwinshi kwamabara LED yerekana biterwa no kwishyiriraho nabi.Kubwibyo, intambwe zigomba gukurikizwa cyane mugihe cyo kwishyiriraho, cyane cyane mugihe cyambere cyo kwishyiriraho.Kugirango tugabanye kugaragara kw'amakosa, reka turebe ibara ryuzuye LED.Igishushanyo cya wiring ya ecran yerekana hamwe nuburyo bwo gukoresha intambwe yo kwishyiriraho ibara ryuzuye LED.
1. Ibara ryuzuye LED yerekana umugozi uhuza igishushanyo
Babiri, inzira zuburyo
1. Reba niba amashanyarazi atanga amashanyarazi yuzuye-LED yerekana bisanzwe.
Shakisha amashanyarazi ahinduka hamwe nibyiza kandi bibi DC ihuza, huza umugozi wamashanyarazi 220V kumashanyarazi, (menya neza ko uhujwe neza, uhuze AC cyangwa NL terminal), hanyuma uhuze amashanyarazi.Noneho koresha uburyo bwa multimeter na DC kugirango upime voltage kugirango umenye neza ko voltage iri hagati ya 4.8V-5.1V, kandi hariho ipfundo iruhande rwayo, ishobora guhindurwa na screwdriver ya Phillips, kandi uburyo bwa DC bukoreshwa mugupima voltage.Kugirango ugabanye ubushyuhe bwa ecran kandi wongere ubuzima bwayo, voltage irashobora guhinduka kuri 4.5V-4.8 aho urumuri rusabwa rutari hejuru.Nyuma yo kwemeza ko ntakibazo kijyanye na voltage, hagarika amashanyarazi hanyuma ukomeze guteranya ibindi bice.
2. Zimya imbaraga zamabara yuzuye yerekanwe.
Huza V + kuri wire itukura, V + kuri wire yumukara, uhuze ikarita yuzuye igenzura LED yerekana ikarita yo kugenzura hamwe na LED paneli, hamwe ninsinga yumukara kurikarita yo kugenzura no gutanga amashanyarazi ya GND.Umutuku uhuza ikarita yo kugenzura + 5V voltage hamwe nubuyobozi bwibice VCC.Buri kibaho gifite insinga.Iyo urangije, genzura ko ihuza ariryo.
3. Huza ibara ryuzuye riyobora umugenzuzi hamwe nubuyobozi bwibice.
Koresha insinga nziza.Nyamuneka nyamuneka witondere icyerekezo kandi ntuhindure isano.Ibara ryuzuye ryerekana kuyobora ibice bifite ibice bibiri bya 16PIN, 1 byinjiza, 1 bisohoka, kandi hafi ya 74HC245 / 244 byinjira, kandi ikarita yo kugenzura ihujwe ninjiza.Ibisohoka bihujwe no kwinjiza ikibaho gikurikira.
4. Huza umurongo wa data RS232 yumurongo wuzuye LED yerekana.
Huza impera imwe yumurongo wamakuru wakozwe kumurongo wa seriveri ya DB9 ya mudasobwa, naho iyindi iherekeza ikarita yuzuye yerekana ikarita yerekana igenzura, uhuze pin 5 (umukara) wa DB9 na GND yikarita igenzura, hanyuma uhuze 3 pin (umutuku) wa DB9 kugenzura RS232-RX yikarita.Niba PC yawe idafite icyambu gikurikirana, urashobora kugura USB kuri RS232 ya seriveri ihinduranya umugozi mububiko bwa mudasobwa.
5. Ongera uhuze ihuza ryuzuye-amabara yerekanwe.
Niba insinga yumukara ihujwe neza na -V na GND, naho insinga itukura ihujwe na + V na VCC + 5V.
6. Fungura amashanyarazi ya 220V hanyuma ufungure software yakuweho ibara ryerekana LED yuzuye.
Mubisanzwe, itara ryamashanyarazi riraka, ikarita yo kugenzura irahari, kandi ibara ryuzuye LED ryerekana.Niba hari ikintu kidasanzwe, nyamuneka reba ihuriro.Cyangwa ugenzure ikibazo.Shiraho ibipimo bya ecran hanyuma wohereze subtitles.Nyamuneka reba amabwiriza ya software.
