2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Ua tus kws tsim khoom siv hluav taws xob, Kuv ib txwm xav kom muaj lub ntsuas hluav taws xob tiv thaiv nqa tau, uas tuaj yeem ntsuas txhua qhov khoom siv hluav taws xob nyob ntawd. Hauv xyoo 2016, Kuv tau tsim kuv tus kheej ib qho Kev Ntsuas Kev Ntsuas raws AVR TransistorTester los ntawm Markus F. thiab Karl-Heinz Kübbeler. Ua raws li qhov ntawd, Kuv rov txhim kho Tus Txheej Txheem Tester rau qhov loj me ntawm cov keychain.

Txij li cov neeg tsim khoom, cov kws tshaj lij thiab cov nyiam ua haujlwm muaj lub khoos phis tawj nyob ib puag ncig peb lub rooj ua haujlwm ib txwm muaj. Yog li kuv xav rau kuv tus kheej vim li cas ho tsis tsim cov khoom ntsuas uas tuaj yeem siv ua USB txuas ntxiv uas tso cai rau peb sim cov khoom sib xyaw. Kuv tau tsim kho software kom mus nrog tus USB tivthaiv tester uas qhia txog qhov yuav tsum tau ntsuas ntsuas ntawm cov zaub hauv daim ntawv tsim me me. Kev xeem ua yog xim xim thiab cov xim no qhia tus pin teeb tsa. Lub software txhawb nqa peb qhov loj OS platforms macOS, Windows thiab Linux.

Ua tsaug ntau rau PCBWAY rau kev txhawb nqa lub tsev no

PCBWay tau hais kom nqis tes thiab pab kuv txhawb txoj haujlwm no. Lawv kuj tau muab lawv cov PCB kev tsim khoom thiab kev pabcuam los ua ke rau kev tsim. Lawv muab 10 tus PCBs kev cai rau qis li $ 5 nrog rau ntau qhov kev xaiv xws li xim xim muag, qhov ua tiav, thiab ntau ntxiv. Lub sijhawm tawm mus rau PCBs tau nrawm heev. Lawv kuj tshuaj xyuas txhua tus PCB tsim tus kheej ua ntej tsim khoom yog li koj tsis tau txais ib qho PCBs puas. Kuv pom zoo sim lawv cov kev pabcuam PCB yog tias koj xav tau.

Kauj Ruam 1: Cia Peb Tau Txais PCBs Tsim Ua Ntej Peb Pib

PCB tau tsim los kom loj li tus ntiv tes xoo nrog txiv neej USB-A txuas. Qhov 3 Cov Ntawv Xaum tau nthuav tawm rau qhov siv qhov ntsuas qhov coj mus rau lawv. Qhov ntev ntawm PCB yog kwv yees li 34mm x 17mm.

Ua tsaug ntau rau PCBWay's Prototyping and Assemble Service kom tau txais kuv cov laug cam tsim thiab sib sau ua ke. Lawv muab cov laug cam zoo rau tus nqi qis thiab pheej yig. Lawv kuj tseem muaj ntau yam kev tiv thaiv daim npog ntsej muag xaiv los sim. Tam sim no, lawv tab tom ua qhov kev xav tsis thoob rau kev pabcuam sib dhos, koj tuaj yeem tau txais 20 lub rooj sib dhos ua ke tsuas yog $ 30 nrog kev xa khoom dawb.

Kauj ruam 2: Soldering Cheebtsam?

Txij li thaum kuv siv PCBWay cov kev pabcuam sib dhos PCBs zoo li huv thiab zoo dua piv rau thaum kuv muab kuv tus kheej tso rau?

Tab sis yog tias koj tsis siv ib qho kev pabcuam sib dhos koj tuaj yeem muab tshuaj txhuam nws ntawm koj tus kheej siv cov tshuaj txhuam kom sov thiab chaw tso cua sov rov qab. Kuv xav kom muaj lub tshuab tsom iav lossis tsom iav ib puag ncig txij li cov khoom siv yog 0603 pob thiab tej zaum yuav nyuaj rau solder yam tsis muaj lawv.

Kauj Ruam 3: Soldering Test Clips

Nco ntsoov xim xaj vim peb yuav siv qhov kev txiav txim ntawd ib pliag, hauv kuv rooj plaub TP1-TP2-TP3 yog Dub, Liab Liab.

Cov xim txhawb los ntawm software yog Dub (B), Ntsuab (G), Dawb (W), Daj (Y), thiab Liab (R) (ntau ntxiv yuav ntxiv sai sai). Peb qhov sib xyaw ua ke ua rau muaj xim xim BRY.

Kauj Ruam 4: 3D Luam Ntawv Case (Yeem Xaiv)

Kuv xa PCB tsim los ntawm Dav dawb hau mus rau Fusion 360 thiab tsim rooj plaub nyob ib puag ncig nws. Cov ntaub ntawv yog 2 ntu tsim nrog snap-haum tsim. Qhov kam rau ua yog nruj heev yog li nws tsis tuaj yeem qhib tau yooj yim.

Koj tuaj yeem rub tawm cov ntawv los ntawm Thingiverse.

Kauj Ruam 5: Teem Cov Kuaj Xim Hauv Firmware

Yog tias koj tsis tau siv tib xim sojntsuam ces ua raws cov lus qhia hauv qab no hla mus rau qib tom ntej.

Hauv cov ntaub ntawv hloov pauv.h hauv cov ntaub ntawv firmware, hloov kab 133

const unsigned char probe_colors_str EEMEM = "BRY";

Kho kom raug "BRY" rau koj tus kheej xim ua ke peb teeb tsa hauv KAUJ RUAM 3.

Qhib Terminal hauv tib lub nplaub tshev thiab khiav cov lus txib hauv qab no

ua kom huv

ua txhua yam

Kauj ruam 6: Hlawv Firmware

Q️ YUAV TSUM:

• Koj yuav xav tau USBasp los hlawv cov ntaub ntawv firmware rau tus ntsuas.
• Koj yuav tsum muaj AVRDUDE teeb tsa hauv koj lub cev txhawm rau ua raws cov lus qhia hauv qab no kom ua haujlwm.

Hauv Terminal/Command Prompt, taw rau lub nplaub tshev qhov chaw nrog cov ntaub ntawv firmware thiab ua raws cov lus txib hauv qab no-

// Flashing.hex thiab.eep cov ntaub ntawv rau MCU

avrdude -c usbasp -B 20 -p m328p -P usb -U nyem: w:./ TransistorTester.hex: a -U eeprom: w:./ TransistorTester.eep: a

Kauj Ruam 7: Desktop Application ??

Daim ntawv thov pib txuas rau tus tivthaiv tivthaiv thaum lub chaw nres nkoj raug xaiv los ntawm tus neeg siv. Daim ntawv thov muaj rau macOS 10+, Windows 8, thiab siab dua thiab Linux.

Rau macOS cov neeg siv, touchBar txhawb nqa kuj tseem muaj.
