Yog tias koj muaj kev nkag siab txog CAN Bus thiab Arduino programming, thiab xav nyiag koj lub tsheb, tom qab ntawv cov lus qhia no tuaj yeem muab kev daws teeb meem rau koj.

Raws li vim li cas koj thiaj xav nyiag koj lub tsheb, Kuv tsis paub, tab sis qhov no yog qhov txaus nyiam tshaj plaws.

Txoj haujlwm no tsuas yog siv Serial CAN Bus Module los ntawm Longan Labs thiab Wio Terminal lub ntsiab tswj hwm los ntawm Seeedstudio.

Serial CAN Bus Module yog CAN Bus control module tsim los ntawm Longan Labs. Nws siv UART los sib tham nrog ib leeg-nti microcomputer. Nws yog compact thiab siv tau yooj yim.

Wio Terminal los ntawm Seeedstuio, uas yog pawg thawj coj txhim kho nrog lub vijtsam uas tuaj yeem ua haujlwm nrog Arduino.

Hauv txoj haujlwm no, cov haujlwm hauv qab no feem ntau tau ua tiav:

Nyeem cov kev caij tsheb kauj vab, kev sib hloov nrawm thiab roj kub thiab lwm yam ntaub ntawv, tso tawm ntawm Wio Terminal screen

Yog tias koj xav tau hnub ntxiv los ntawm lub tsheb, thov mus saib

Kauj Ruam 1: Cov Ntsiab Lus Taw Qhia

Yuav luag txhua lub tsheb niaj hnub muaj OBD-II interface, uas yog tus choj ntawm lub tsheb thiab lub ntiaj teb sab nrauv. Peb tuaj yeem tau txais tag nrho cov ntaub ntawv tsheb thiab tswj lub tsheb los ntawm OBD-II interface.

Thiab, nws yog qhov txaus ntshai los tswj lub tsheb, koj yuav tsum muaj kev nkag siab tob ntawm OBD-II interface ua ntej mus. Kab lus no tsuas yog nyeem qee cov ntaub ntawv yooj yim los ntawm lub tsheb, yog li koj tuaj yeem nyab xeeb ua raws cov theem hauv cov lus qhia no.

Kauj ruam 2: Cov npe

• Wio Terminal
• Wio Terminal Roj Teeb Chassis
• OBD-II CAN-BUS Cov Khoom Txhim Kho

Lus Cim Tseem Ceeb: Txoj haujlwm no xav tau V1.3 version lossis tom qab ntawm Serial tuaj yeem caij npav.

Kauj ruam 3: Soldering

Qhov no yuav yog cov kauj ruam nyuaj tshaj plaws, yog tias koj tsis tau siv cov hlau txuas ntxiv.

Peb yuav tsum tau muab cov hlau txuas los ntawm OBD-II CAN-BUS Dev cov khoom siv rau OBD-txuas. Koj tuaj yeem saib ntawm daim duab, peb tau xaim xaim liab rau 6pin ntawm tus txuas, thiab xaim dub mus rau 14pin. Thaum 6pin sawv cev rau CANH, 14pin sawv cev rau CANL

Kauj Ruam 4: Kev Kho Vajtse Txuas

1. Serial CAN Bus Module suav nrog OBD-II CAN-BUS Dev cov khoom siv txuas nrog Wio Terminal UART interface ntawm Grove cable
2. Txuas cov xov hlau los ntawm cov kauj ruam dhau los rau Serial CAN Bus Module, txuas liab rau CANH thiab dub rau CANL.

Kauj ruam 5: Software thiab Chaw

Ntawm no peb yuav tsum tau teeb tsa qee qhov rau cov npav tuaj yeem tuaj yeem ua qauv.

Ua ntej peb pib, peb yuav tsum rub cov cai ntawm txoj haujlwm no. Koj tuaj yeem rub tawm lub tsev qiv ntawv thiab lub tsev qiv ntawv koj xav tau los ntawm qhov txuas no.

Yog tias koj siv wio davhlau ya nyob twg thawj zaug, koj tuaj yeem tshawb xyuas wiki rau wio davhlau ya nyob twg

Ua ntej, peb qhib qhov teeb tsa ua piv txwv hauv daim duab, qhov uas peb yuav teeb tsa lub npog ntsej muag thiab lim ntawm cov ntawv tuaj yeem tuaj yeem npav npav.

Tom qab ntawd hlawv qhov teeb tsa ua piv txwv rau wio lub davhlau ya nyob twg, qhib lub vijtsam txuas thiab sau tus cim ntawm qhov tsis pom los saib seb qhov kev teeb tsa ua tiav lossis tsis.

Tom qab teeb tsa tiav, hlawv qhov demo mus rau wio davhlau ya nyob twg thiab koj tuaj yeem pom cov ntaub ntawv ntawm lub vijtsam.

Kauj Ruam 6: Xeem Tsheb

Tom ntej no, peb yuav tsum mus rau lub tsheb thiab sim nws. Koj tuaj yeem pom OBD-II interface hauv qab lub kauj, ntsaws qhov txuas rau hauv OBD-II interface, tig rau wio davhlau ya nyob twg, thiab koj tuaj yeem pom qhov tshwm sim.

Kauj Ruam 7: Dab Tsi Yuav Kho Kom Zoo

Wio yog pawg tswj hwm tseem ceeb muaj zog, peb siv ob peb lub zog hauv nws.

Piv txwv li, Bluetooth, wi-wifi, thiab lwm yam.

Tau kawg, koj tseem tuaj yeem ua tus interface zoo nkauj dua. Hauv ntej, koj tuaj yeem ua si thiab txaus siab rau cov txheej txheem tsim khoom.
