Ntse IC Tester: 7 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Peb txhua tus paub tias IC Testers ua dab tsi … Feem ntau, IC tus lej raug pub rau hauv IC Tester thiab kev sib piv tau ua tawm tsam qhov tshwj xeeb IC's Logic Table.

Tus ntsuas IC ntse yog qhov muaj peev xwm ntau dua thiab zoo dua li IC Tester tus qauv, nws muaj peev xwm txheeb xyuas thiab txheeb xyuas IC txuas nrog nrog phau ntawv hom. Peb IC Tester nta Touch LCD uas muab cov neeg siv tau zoo dua thiab nkag siab yooj yim UI.

IC Testers tej zaum yuav siv cov cuab yeej siv kim tab sis qhov no tsuas yog qis dua ₹ 1600 (~ $ 25), pheej yig zoo li?

Kauj Ruam 1: Cia Peb Khw Qee Yam Khoom

Electronics

• 1 x Arduino Mega 2560
• 1 x 20 Pin ZIF
• 1x 2.4 nti TFT kov Screen LCD nrog inbuilt SD Card Qhov
• 1 x 4GB MicroSDHC
• 1x 6-pin Ntxiv Ntev Poj Niam Header
• 3x 8-pin Ntxiv Ntev Poj Niam Header
• 1x Txiv neej Header Sawb
• 2x WS2812B (Tsis teb los tau)
• 2x 100 nF 0805 Capacitor (Tsis teb los tau)
• 1x 180Ω0805 Resistor (Tsis teb los tau)

Cov Cuab Yeej thiab Cov Khoom Siv Ntxiv

• Soldering Hlau
• Solder
• Lub Laptop
• USB Cable txuas Arduino Mega 2560
• MicroSDHC Adapter

Kauj Ruam 2: Tsim PCB

Kuv tsim cov ntaub thaiv npog rau txhua qhov khoom siv kom haum thiab xaiv Arduino Mega ua kuv tus tswj hwm micro txij li ob qho tib si ZIF Qhov (Socket) thiab LCD tuaj yeem muab tso rau ib sab ntawm ib sab muab kev tsim kom zoo nkauj thiab nqa tau zoo thiab hnov. Kuv siv Autodesk Eagle rau PCB Tsim ib feem (Kuv tau txuas cov ntaub ntawv dav dawb hau hauv qab no).

Kev hais tawm loj rau cov hais mav ntawm JLC PCB rau kev txhawb nqa PCBs rau txoj haujlwm. Txheeb xyuas lawv tawm lawv muab $ 2 PCB Prototyping thiab xa khoom dawb ntawm Thawj Qhov Kev Txiav Txim.

Kauj ruam 3: Kaw thiab Solder

Thaum koj muaj tag nrho cov khoom siv nrog rau PCB, tsuas yog muab lawv tso rau hauv qhov chaw raws li qhia thiab koj npaj txhij mus !!

Thaum koj ua tiav nrog cov laug muab tso rau ntawm LCD Shield thiab Poj Niam Headers thiab qhov no ua tiav koj li kev sib dhos rau IC Tester.

Nco ntsoov - "Yog tias nws hnov tsw zoo li qaib, koj ua tsis raug";)

Kauj ruam 4: Code? Yog..

Qhib koj Arduino IDEs thiab Qhib qhov chaws… Koj tuaj yeem hloov kuv lub npe nrog koj tus kheej yog li nws khau nrog koj lub npe. Koj muaj kev ywj pheej ua si ib puag ncig nrog cov phiaj xwm xim raws li qhov koj xaiv.

Txhua cov ntaub ntawv muaj nyob ntawm GITHUB

Kauj Ruam 5: Npaj Database … Ua Haujlwm Siv Sijhawm

Kuv tau suav sau cov ntaub ntawv yooj yim rau Kev Txheeb Xyuas Cheeb Tsam uas suav nrog ICs yooj yim. Cov ntaub ntawv khaws cia hauv database.txt cov ntaub ntawv ntawm GitHub. Luam daim ntawv txt no ntawm SD Card thiab ntxig rau hauv Touch LCD Shield.

Ua tsaug rau cov neeg siv qhia JorBi rau nws Cov Lus Qhia - Arduino IC Tester los ntawm qhov uas kuv tau txais kev tshoov siab los tsim ib qho.

Txawv -

$ [Tus lej IC]

[IC Lub Npe]

[Tus pin]

[Case Case 1]

[Case Case 2]

…

[Xeem Case N]

Qauv Xeem Case-

Hais tias kuv muaj IC-7426, rooj plaub piv txwv yuav yog

0000HHG000000VQhov no 0/1 yuav raug siv los qhia kom nkag siab thiab H/L (Siab/Tsawg) txhawm rau qhia cov zis thiab V siv los qhia VCC thiab G yog siv los qhia hauv av. Ua raws li kev txiav txim los ntawm Pin 1, 2, 3,….. 7, 8, 9,…. 14 rau saum IC

Kauj Ruam 6: Ntiv Tes Hla !! Kuaj Txhua Qhov Ua Ke

Cia peb Upload cov cai thiab khau raj IC Tester.

Ntiv tes hla !!

Thiab nws ua haujlwm zoo

Kauj Ruam 7: Zoo Siab Kuaj

Koj zoo siab tos txais los pab rau txoj haujlwm thiab database ntawm GitHub.
