Nyob Zoo Fixers
Nrog Cov Ntawv Qhia Kuv yuav qhia koj yuav ua li cas sib sau ua ke thiab siv IC-Tester txhawm rau txhawm rau txhim kho cov cuab yeej hluav taws xob uas tau tsim nrog kev sib txuas ua ke 7400 thiab 4000 series.
Cov Lus Qhia yog tsim los ntawm kev txhawb siab ntawm txoj haujlwm, qhia luv luv rau kev sib txuas ua ke, tus qauv ntawm IC Tester thiab Cov Lus Qhia Los Ua Ke.
Tom qab sib dhos cov vis dis aus muaj kom nkag siab txog plaub hom kev ua haujlwm.
Txhua Arduino Code thiab Solid Works cov ntaub ntawv tau txuas rau hauv qab.
Kauj Ruam 1: Vim Li Cas Siv Tau?
Kev kho hluav taws xob yog ib txoj haujlwm nyuaj thiab dav, feem ntau tuaj yeem yog txoj haujlwm tsis muaj qhov kawg lossis tsis yooj yim sua kom paub qhov teeb meem thiab siv qhov kev daws teeb meem raug. Kho cov cuab yeej hluav taws xob ua rau nyuaj dua thaum tsis muaj cov ntaub ntawv uas yuav tshwm sim rau ob qho laj thawj:
- Schematic ntawm tag nrho cov cuab yeej tsis tau qhia tawm.
- Cov tebchaw tsis tag.
Thaum sim kho lub cuab yeej yog tias cov sib txuas tsis tuaj yeem txheeb xyuas tau ces peb tsis tuaj yeem paub yog tias cov sib xyaw ua haujlwm raug, yuav ua li cas cov khoom sib xyaw yuav tsum ua haujlwm thiab qhov phem tshaj: peb tsis paub yuav hloov nws li cas !!!
Hmoov zoo, feem ntau ntawm cov hauv paus yooj yim xws li cov neeg tiv taus, lub tshuab hluav taws xob lossis diodes yog lub Hoobkas tau suav nrog qhia qhov tseem ceeb, txwv, zam …
Qhov ntawd yog kev txhawb siab los piav qhia IC Tester uas lub luag haujlwm tseem ceeb yuav yog txhawm rau txheeb xyuas thiab txheeb xyuas cov kev sib txuas ua ke.
Kauj Ruam 2: Taw qhia luv luv rau Kev Sib Koom Ua Ke
Cov Hluav Taws Xob Hluav Taws Xob kuj tseem hu ua IC lossis nti yog txheej txheej hluav taws xob ua los ntawm cov khoom siv hluav taws xob. Cov txheej txheem no tau ntim rau hauv cov thawv yas me uas dhau los ntawm cov xim hlau tso cai rau kev sib cuam tshuam ntawm cov txheej txheem sab hauv ntawm cov nti nrog sab nraud.
Txhua tus pin ntawm IC muaj qhov tshwj xeeb ua haujlwm thiab cov khoom uas tuaj yeem pom ntawm cov ntaub ntawv teev npe ntawm cov chips. Lwm cov ntaub ntawv muaj txiaj ntsig pom ntawm cov ntaub ntawv khaws tseg yog qhov tseeb, lub rooj uas qhia txog tus cwj pwm uas ua tau ntawm kev sib koom ua ke, nyob ntawm txhua qhov nkag uas tau thov rau IC raws li kev nkag, qhov tseeb yuav muab rau peb lub xeev ntawm txhua qhov txiaj ntsig.
Raws li qhov piv txwv daim duab saum toj no qhia tus lej npe ntawm 4002 IC nrog rau qhov tseeb uas piav qhia lub xeev ntawm nY Kev Tso Tawm rau txhua qhov ua tau nA, nB, nC thiab nD Cov tswv yim. Yog tias txhua qhov kev nkag mus yog L qhov tso tawm yuav yog H…
Thaum ntsuas, txhawm rau txheeb xyuas thiab txheeb xyuas lub nti peb yuav sib piv cov nti tus cwj pwm rau nws raws qhov tseeb, tom qab ntawd peb yuav tuaj yeem txheeb xyuas qhov twg tus pin peb tau khaws cia hauv peb lub cim xeeb. Txawm li cas los xij, ntawm txoj haujlwm no, peb tab tom pib sim tsuas yog 7400 thiab 4000 IC series.
Kauj Ruam 3: Tus Qauv Ic-Tester
IC-Tester yog tsim los ntawm rau tus qauv ua haujlwm. Qhov tseem ceeb tshaj plaws yog Arduino board Mega 2560 uas yuav yog lub hlwb ntawm peb lub cuab yeej. Mega 2560 yuav tswj hwm thiab txuas tag nrho lwm cov txheej txheem tau txais thiab xa cov ntaub ntawv raws li Arduino code yuav hais tawm.
Lub Laptops yuav siv los sau cov lej Arduino thiab sau rau hauv pawg thawj coj.
EEPROM, hluav taws xob tshem tawm qhov programmable nyeem tau nkaus xwb, lub cim xeeb tsis hloov pauv yuav khaws txhua cov ntaub ntawv los ntawm cov lus tseeb ntawm cov kab hluav taws xob uas peb xav sim. Peb yuav siv 24LC256 EEPROM.
Kev sib cuam tshuam nrog tus neeg siv yuav ua tiav los ntawm cov zaub, 1602 LCD thiab cov nyees khawm tswj.
Thaum kawg kev sib txuas lus ntawm IC-Tester thiab Circuit Court los ntsuas yuav tshwm sim los ntawm IConnect uas yuav txuas rau tus pin ntawm kev sib txuas hauv Circuit Court los ntsuas.
Txhua qhov kev sib txuas yuav raug qhia kom raug nrog Schematic ntawm Kauj Ruam tom ntej.
Kauj ruam 4: Schematic
Thaum lub rooj sib tham ntau qhov kev sib txuas yuav tshwm sim, muaj Schematic yog qhov kev pab loj los txo qhov ua yuam kev thiab lub sijhawm qhia meej txhua kab lus.
Feem ntau ntawm cov kev sib txuas, tshwj tsis yog Eeprom tuaj yeem hloov kho nyob ntawm qhov teeb meem zaum kawg, tsis muaj teeb meem hloov pauv kev sib txuas mus rau Arduino, tab sis Arduino code yuav tsum raug hloov kho.
Nco ntsoov tias muaj ob lub qauv IConnect, ib qho piv txwv thiab lwm yam digital, txhua qhov rau kev ua haujlwm sib txawv.
Txhua qhov kev hloov pauv siv rau kev tswj hwm tus neeg siv thiab cuam tshuam nrog LCD yuav pov tseg nws tus kheej LED uas yuav pom kev thaum lub khawm tswj tau tuaj yeem nias.
Kauj Ruam 5: Cov Lus Qhia Los Ua Ke
Taw qhia, Schematic thiab 16 Cov Kauj Ruam los ua ke IC-Tester.
Txaus siab rau
Kauj Ruam 6: Txoj Cai Flowchart
Plaub hom kev ua haujlwm tuaj yeem nkag mus los ntawm cov nyees khawm tseem ceeb los ntawm nias lub pob xaiv, lossis khawm qis kom txav mus rau hom tom ntej.
1. Txheeb xyuas IC yuav cuam tshuam nrog kev sib koom ua ke txhawm rau sim thiab EEPROM, thaum kawg, peb yuav tau txais lub npe IC xeem yog tias pom.
2. Txheeb xyuas IC siv IConnect yuav kuaj cov kab hluav taws xob tau txais tag nrho lub xeev tus pin.
3. Saib Cov Ntaub Ntawv yuav qhia rau ntawm LCD tag nrho cov ntaub ntawv khaws tseg ntawm EEPROM.
4. Hloov IC yuav muab los ntawm IConnect txhua qhov kev xav tau xa mus rau hauv Circuit Court mus txog qhov hloov pauv ib nrab ntawm ib qho kev sib xyaw ua ke.
Kauj Ruam 7: Cov Qauv Tsim
Txhua qhov kev tsim qauv tau ua nrog Khoom Ua Haujlwm tuaj yeem rub tawm rau kev hloov pauv thiab 3D luam ntawv.
Kauj ruam 8: Cov ntaub ntawv
1. Khoom Ua Haujlwm
2. Luam Ntawv 3D
3. Arduino Code (IC Qhov tseeb sab hauv)
