LED zaub screensyog cov khoom siv hluav taws xob, thiab qee zaum yuav muaj qee qhov teeb meem.Hauv qab no, peb yuav qhia ntau yam kev daws teeb meem.
01 Dab tsi yog vim li cas rau ob peb vib nas this ntawm cov kab ci lossis qhov muag tsis pom duab ntawm lub vijtsam LED thaum nws pib ua haujlwm thawj zaug?
Tom qab txuas lub vijtsam loj rau lub khoos phis tawj, HUB faib pawg thawj coj saib, thiab tshuaj ntsuam kom zoo, nws yog ib qho tsim nyog yuav tsum tau muab cov ntaub ntawv pov thawj.+ 5V fais fab movmus rau tus maub los kom paub meej tias nws txoj haujlwm li qub (lub sijhawm no, tsis txhob txuas ncaj qha rau 220V voltage).Thaum lub sijhawm fais fab tuag, yuav muaj ob peb vib nas this ntawm cov kab ci ntsa iab lossis "blurred screen" ntawm lub vijtsam, uas yog ib qho kev sim tshwm sim, ceeb toom rau tus neeg siv tias lub vijtsam tab tom pib ua haujlwm ib txwm.Hauv 2 vib nas this, qhov tshwm sim no yuav ploj mus thiab lub vijtsam yuav nkag mus rau hom kev ua haujlwm ib txwm muaj.
02 Vim li cas nws tsis tuaj yeem thauj khoom lossis sib txuas lus?
Cov laj thawj ntawm kev sib txuas lus tsis ua haujlwm thiab kev thauj khoom tsis ua haujlwm yog qhov zoo ib yam, uas tuaj yeem tshwm sim los ntawm cov laj thawj hauv qab no.Thov sib piv cov khoom teev nrog kev ua haujlwm:
1. Xyuas kom meej tias cov cuab yeej tswj qhov system kho kom raug zoo.
2. Tshawb xyuas thiab paub meej tias cov kab hluav taws xob serial siv los txuas rau tus maub los yog txoj kab ncaj nraim, tsis yog kab sib tw.
3. Tshawb xyuas thiab paub meej tias qhov chaw nres nkoj sib txuas xov hlau tsis zoo thiab tsis muaj qhov xoob lossis detachment ntawm ob qho kawg.
4. Muab piv rau LED npo tswj software nrog rau daim npav tswj koj tau xaiv los xaiv cov qauv khoom raug, txoj kev sib kis, tus lej chaw nres nkoj, thiab tus nqi sib kis.Teem qhov chaw nyob thiab serial kis tus nqi ntawm kev tswj qhov system hardware kom raug raws li qhov muab dial hloov daim duab hauv software.
5. Xyuas seb lub jumper cap yog xoob los yog detached;Yog hais tias lub jumper cap tsis xoob, thov xyuas kom meej tias cov kev taw qhia ntawm lub jumper cap yog lawm.
6. Yog tias tom qab kuaj xyuas thiab kho cov lus saum toj no, tseem muaj teeb meem nrog kev thauj khoom, thov siv lub tshuab multimeter los ntsuas seb qhov chaw nres nkoj ntawm lub khoos phis tawj txuas nrog lossis kev tswj hwm qhov system puas lawm, kom paub meej tias nws yuav tsum tau xa rov qab mus rau lub chaw tsim khoom siv computer. los yog tswj qhov system hardware rau kev sim.
03 Vim li cas lub vijtsam LED tshwm dub tag?
Hauv cov txheej txheem ntawm kev siv cov tshuab tswj, peb qee zaus ntsib qhov tshwm sim ntawm LED cov ntxaij vab tshaus tshwm dub tag.Tib qhov tshwm sim tuaj yeem tshwm sim los ntawm ntau yam sib txawv, txawm tias cov txheej txheem ntawm kev tshuaj ntsuam tig dub yuav txawv nyob ntawm kev ua haujlwm sib txawv lossis ib puag ncig.Piv txwv li, nws tuaj yeem tig dub thaum lub sijhawm fais fab, nws tuaj yeem tig dub thaum thauj khoom, lossis nws yuav tig dub tom qab xa, thiab lwm yam:
1. Thov xyuas kom meej tias tag nrho cov khoom siv kho vajtse, nrog rau cov kev tswj hwm, muaj lub zog zoo.(+ 5V, tsis txhob thim rov qab lossis txuas tsis raug)
2. Tshawb xyuas thiab paub meej tias ntau zaus seb cov kab hluav taws xob siv los txuas rau tus maub los yog xoob lossis tshem tawm.(Yog tias nws tig dub thaum lub sijhawm thauj khoom, nws yuav yog vim li no, uas yog, nws raug cuam tshuam vim cov kab sib txuas lus xoob thaum lub sijhawm sib txuas lus, yog li lub vijtsam tig dub. Tsis txhob xav tias lub vijtsam lub cev tsis txav. , thiab cov kab tsis tuaj yeem xoob Thov xyuas koj tus kheej, uas yog qhov tseem ceeb rau kev daws teeb meem sai.)
3. Tshawb xyuas thiab paub meej tias puas yog lub HUB faib khoom txuas nrog lub vijtsam LED thiab daim npav tswj lub ntsiab yog nruj nreem txuas thiab ntxig rau pem hauv ntej.
04 Yog vim li cas vim li cas tag nrho lub vijtsam ntawm lub rooj tsavxwm tsis ci lossis tsis pom kev
1. Saib xyuas cov fais fab cables, 26P ribbon cables nruab nrab ntawm chav tsev boards, thiab lub hwj chim module qhov taw qhia teeb kom pom tias lawv ua haujlwm zoo.
2. Siv lub multimeter los ntsuas seb lub rooj tsav xwm hauv chav tsev puas muaj qhov hluav taws xob zoo li qub, thiab tom qab ntawd ntsuas seb qhov hluav taws xob tawm ntawm lub hwj chim module puas zoo li qub.Yog tsis yog, nws raug txiav txim tias lub hwj chim module yog faulty.
3. Ntsuas qhov tsawg voltage ntawm lub hwj chim module thiab kho qhov zoo hloov (ze ntawm qhov taw qhia lub teeb ntawm lub hwj chim module) kom ua tau raws li tus qauv voltage.
