2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Cov qauv no npog yuav ua li cas thiaj ua rau cov khawv koob zoo caum cov teeb LED rau koj tus hlub, txiv, niam, phooj ywg hauv chav kawm thiab cov phooj ywg zoo. Qhov no yooj yim heev los tsim kom ntev li ntev tau koj ua siab ntev. Kuv pom zoo kom muaj qee qhov kev paub dhau los yog tias koj tsim qhov no. Rau cov khoom siv ntxiv koj tuaj yeem tau txais ntawm no

Cov ntaub ntawv:

35 x 1k (lossis 510) ohm resistors

34 x 5mm LED qhov muag teev

2 x 33pF ceramic capacitors

1 x 11.0592mHz siv lead ua oscillator

1 x 10uf/25v electrolytic capacitor

1 x tus kheej ntsuas phoo hloov

1 x Mini USB chaw nres nkoj

1 x 4 tus pin header pin

1 x 40 pin pin

1 x stc89c52 microchip

1 x hlub lub plawv PCB

1 x acrylic plhaub

Kauj ruam 1:

Kev tso cov axial-lead resistor yog qhov yooj yim heev. Raws li peb txhua tus paub, axial-lead resistor tsis muaj polarity, koj tsis tas yuav txheeb xyuas qhov anode thiab cathode thaum tso.

Kauj Ruam 2: Soldering cov Resistors Ib Leeg Ib Leeg

Kuv pom tias nws yooj yim dua los txhuam cov resistor ntawm ib sab. Tom qab tag nrho cov resistors tau muab muag, tom qab ntawd txiav tawm ob txhais ceg ntawm txhua tus tiv thaiv sab tom qab ntawm PCB. Koj yuav tsum tau ceev faj nrog cov seem ntawm cov ceg txiav ntawm PCB uas lawv yuav ua rau koj txhais tes.

Kauj Ruam 3: Solder Crystal Oscillator thiab Ceramic Capacitors rau hauv PCB

Crystal oscillator thiab ceramic capacitor tsis muaj qhov sib txawv. Koj

cia li ntxig rau lawv rau hauv PCB thiab tom qab ntawd siv cov laug. Thaum ua tiav cov laug, txiav tawm ob txhais ceg ntawm lawv. Koj yuav tsum xyuas kom tus oscillator ua raws li PCB lossis nws tuaj yeem ua teeb meem hauv kev sib sau cov microchip mus rau 40-pin qhov (socket) hauv qib kawg.

Kauj Ruam 4: Muab lub Electrolytic Capacitor tso rau hauv PCB

Thov NCO TSEG tias cov electrolytic capacitor muaj polarity. Koj yuav tsum txheeb xyuas qhov anode thiab cathode ua ntej yuav siv qhov muag. Cov ceg ntev dua yog anode. Koj yuav tsum tau ntxig cov ceg ntev rau hauv '+' sab thiab khaws cov ceg ntev txaus kom ua qee qhov muaj peev xwm ua kom pw tsaug zog. Yog tias koj khaws lub tshuab hluav taws xob sawv, koj yuav tsis tuaj yeem ua ke lub microchip hauv qib kawg.

Kauj Ruam 5: Siv lub 40-pin Socket rau hauv PCB

Koj yuav tsum tau ntxig lub qhov (socket) no rau hauv PCB kom raug. Thov ceev faj ntawm lub cim ib nrab ntawm ob lub qhov (socket) thiab PCB. Lawv yuav tsum nyob rau tib txoj kev.

Kauj Ruam 6: Muab lub LED tso rau hauv PCB

Lub teeb LED muaj qhov sib txawv, koj yuav tsum txheeb xyuas qhov anode thiab cathode thiab tom qab ntawd ntxig lawv rau hauv PCB ib qho los ntawm ib qho ua ntej yuav siv tau. Cov coj ntev dua yog tus pin anode thaum luv dua ceg yog cathode. Yog tias ib tus neeg tau txiav cov ceg, sim nrhiav lub tiaj tiaj ntawm LED sab nrauv. Tus pin nyob ze ntawm lub tiaj tiaj yuav yog qhov tsis zoo, tus pin cathode.

Tus pin ntev dua ntawm LED yuav tsum tau muab tso rau hauv lub qhov ze ntawm lub cim + Tom qab koj ntxig tag nrho cov qij LED rau hauv PCB, koj yuav tsum xyuas kom cov LEDs tau ua raws li PCB.

Cov ceg LED uas seem hauv daim duab saum toj no zoo li askew. Koj yuav tsum rub tus ceg LED thiab ua kom nws sib dhos rau PCB thiab tom qab ntawd txhuam ib ceg nkaus xwb. Rau kev hloov kho lub hom phiaj, thov tawm lwm ceg mus rau qhov hloov pauv thib ob.

Thaum koj ua kom ntseeg tau tias txhua lub LED tau ua raws PCB, koj tuaj yeem txuas lwm ceg thiab txiav tawm ob txhais ceg ntxiv.

Kauj Ruam 7: Muab lub Mini USB Port thiab Hloov Rau Hauv PCB

Kauj Ruam 8: Ntxig Microchip rau hauv Qhov Ntsuas

KOJ YUAV TSUM PAUB NTAWV NTAWV KAUJ RUAM !!!

Thaum koj thawj zaug tau txais tsuas yog hais txog ib qho DIP IC, ob txhais ceg yuav tsis zoo ib yam rau lub cev nti loj. Ob txhais ceg yuav khoov me ntsis. Hauv kuv qhov kev paub, nws yog qhov zoo tshaj los kho lawv ua ntej sim nkag mus rau hauv IC qhov (socket). Nws yog ib qho tseem ceeb heev uas cov kauj ruam no yuav tsum tau ua nrog kev saib xyuas, kom tsis txhob ua puas rau cov chips kim. Mus qeeb, siv lub teeb nrawm, thiab siv koj lub sijhawm. Nkag mus rau IC nrog 2 txhais tes thiab ua kom cov pins ua raws li lub desktop. Koj xav khoov tus pin tib lub sijhawm kom lawv khoov txoj cai qhov pins hloov los ntawm dav mus rau nyias, siv qeeb, khov kho, thiab txawm tias siab kom khoov lawv tag nrho ib zaug kom txog thaum lawv mus ncaj ntawm lub nti.

(Kuv siv ib txhais tes los tuav lub IC kom zoo rau lub kaum ntse ntse tua, koj yuav tsum siv 2 txhais tes).

Tam sim no, nws yog lub sijhawm los teeb tsa IC rau hauv lub qhov (socket). Ua ntej txhim kho, peb yuav tsum nrhiav txoj hauv kev. Ib nrab ib ncig ntawm ob qho ntawm IC thiab lub qhov (socket) yuav tsum nyob hauv tib qho kev qhia.

Thaum koj muaj kev taw qhia nti, peb tuaj yeem pib txhim kho nws. Koj xav kom muaj peev xwm saib hauv qab nti ntawm kab uas koj tab tom tso. Lub hom phiaj ntawm no yog TSIS tso lawv rau hauv lub qhov (socket)! Txog tam sim no, peb xav kom ntseeg tau tias peb muaj lawv nyob hauv lub qhov kom raug. Kho lub nti raws li xav tau kom tau txais txhua sab ntawm 20 tus pin ntawm kab sib tw zaum zaum, npaj txhij nias. Yog tias muaj cov pins khoov ntawm kab thiab tsis zaum hauv lub qhov (socket), koj yuav tsum coj nws mus thiab ua kab ntawm cov pins ua raws li lub khoos phis tawj, rov ua cov txheej txheem khoov dua kom txog thaum txhua sab ntawm 20 tus pin haum rau hauv lub qhov IC qhov (socket) Tam sim no tias tag nrho 40 tus pin nyob hauv qhov tsim nyog, siv lub zog me ntsis nyob nruab nrab ntawm ob qho kawg ntawm lub nti. Coj nws qeeb, thiab saib seb puas muaj cov pins ntes thiab tsis kam nkag mus rau hauv qhov. Kho lawv raws li xav tau. Sai li koj paub tseeb tias lawv txhua tus mus raws li tau npaj tseg, nce siab kom txog thaum nws yuav tsis nqis mus ntxiv.

Nrog koj zoo siab !!! Ib feem ntawm PCB tau sib sau ua tiav.
