LED Erekana Ibibazo Rusange nibisubizo

LED yerekana ni kimwe mu bicuruzwa bya elegitoroniki bizwi cyane, ariko uko ibicuruzwa byakoreshwa, hazabaho kunanirwa gutandukanye. Byagenda bite niba bihenze gusaba umuntu kugisana? Turi hano kugirango tumenye ibibazo nibisanzwe hamwe nibisubizo.

Imwe, ecran yose ntabwo yaka (ecran yumukara).
1. Reba niba amashanyarazi yatanzwe.
2. Reba niba insinga ya signal na USB yahujwe kandi niba ihujwe nabi.
3. Reba niba itara ryatsi riri hagati yikarita yoherejwe hamwe namakarita yakira yaka.
4. Niba kwerekana mudasobwa birinzwe, cyangwa ahantu herekanwa mudasobwa ni umukara cyangwa ubururu bwera.

Babiri, LED yose module ntabwo yaka.
1. Icyerekezo gitambitse cya moderi nyinshi za LED ntabwo zimurika, reba niba imiyoboro ya kabili iri hagati ya module isanzwe ya LED na module idasanzwe ya LED ihujwe, cyangwa niba chip 245 ari ibisanzwe.
2. Icyerekezo gihagaritse cyama moderi menshi ntabwo ari meza, reba niba amashanyarazi yiyi nkingi ari ibisanzwe.

Bitatu, hejuru imirongo myinshi ya LED module ntabwo yaka
1. Reba niba umurongo pin uhujwe na 4953 isohoka pin.
2. Reba niba 138 ari ibisanzwe.
3. Reba niba 4953 ishyushye cyangwa yatwitse.
4. Reba niba 4953 ifite urwego rwo hejuru.
5. Reba niba pin zo kugenzura 138 na 4953 zahujwe.

Bane, LED module ibura ibara
Reba niba amakuru ya 245RG afite ibisohoka.
　

Gatanu, igice cyo hejuru igice cyangwa igice cyigice cya LED module ntabwo yaka cyangwa ngo yerekane bidasanzwe.
1. Niba hari ibimenyetso bya OE kumaguru ya 5 ya 138.
2. Niba ibimenyetso byamaguru ya 11 na 12 ya 74HC595 nibisanzwe; (SCLK, RCK).
3. Niba ibimenyetso bya OE bihujwe nibisanzwe; (fungura uruziga cyangwa uruziga rugufi).
4. Niba ibimenyetso bya SCLK na RCK byerekana imirongo ibiri yimirongo ihuza 245 nibisanzwe; (fungura uruziga cyangwa uruziga rugufi).

Igisubizo:
1. Huza ikimenyetso cya OE kuri
2. Huza ibimenyetso bya SCLK na RCK neza
3. Huza uruziga rufunguye hanyuma uhagarike uruziga rugufi
4. Huza uruziga rufunguye hanyuma uhagarike uruziga rugufi

Gatandatu, umurongo kuri LED module cyangwa umurongo wa module ijyanye ntabwo ari mwiza cyangwa ngo yerekanwe bidasanzwe
1. Reba niba imirongo yerekana ibimenyetso bya module ihuye yagurishijwe cyangwa yabuze.
2. Reba niba pin ihuye nikimenyetso cyumurongo na 4953 yaciwe cyangwa igufi-izengurutswe nibindi bimenyetso.
3. Reba niba abarwanya epfo na ruguru ibimenyetso byumurongo batagurishijwe cyangwa babuze kugurisha.
4. Niba ibimenyetso byumurongo bisohoka kuri 74HC138 hamwe na 4953 bihuye birahagaritswe cyangwa bigufi-bizunguruka hamwe nibindi bimenyetso.

Umuti wo gutsindwa:
1. Kugurisha gusudira kubura no kubura
2. Huza uruziga rufunguye hanyuma uhagarike uruziga rugufi
3. Uzuza ibikoresho bitagurishijwe hanyuma usudire wabuze.
