2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Koj puas muaj txoj haujlwm uas xav tau kev cuam tshuam rau kev khaws cia ntau, tab sis tsis muaj peev txheej los tsim cov pawg thawj coj tawg rau lub qhov rooj txheem? Hauv Cov Lus Qhia no, koj yuav kawm paub yuav ua li cas daim npav SD daim npav uas ntsaws ncaj rau hauv lub khob cij rau tsawg dua ob daus las hauv ntu (nyob ntawm seb koj tau txais lawv li cas). Kuv qhia koj yuav siv qhov yooj yim tus pin ncaj lub taub hau thiab hloov kho nws li cas koj tuaj yeem ntsaws rau hauv daim npav SD thiab txuas ncaj qha mus rau lub khob cij rau khaws cov ntaub ntawv thiab ua qauv. Qhov no yog nrawm thiab yooj yim yog li koj tsis tas yuav tos lub qhov (socket) hauv kev xa ntawv, lossis tsim/yuav SMD pawg thawj coj tawg rau nws ib yam. Cov txuj ci yooj yim soldering thiab cov cuab yeej siv tau yog xav tau. Kuv yuav npog yuav ua li cas kom ntsug thiab txoj cai kaum nyob. Qhov 7 lossis 8 tus pin yuav tsum ua haujlwm. 9 tus pin yuav xav tau qee qhov kev hloov kho, Kuv tsuas yog siv 7.

Kauj Ruam 1: Sau Cov Cuab Yeej thiab Cov Khoom

Koj yuav xav tau: SolderSoldering Iron, Kuv siv 45 watt tab sis qhov no ntau dua li txaus Nedlenose pliersa vise yog qhov muaj txiaj ntsig zoo kom tsis txhob hlawv koj tus kheej thiab tsawg kawg 21 tus pin ntawm cov txiv neej ncaj tawm lub taub hau taub hau Radioshack tsis nqa lawv kom deb li kuv paub, tab sis lawv tuaj yeem xaj los ntawm ntau qhov chaw nyob ib puag ncig internet kom pheej yig heev. Nws yog 2 daus las rau 40 pins ntawm kuv lub khw khw. Nov yog qhov digikey, nws yog me ntsis ntxiv uas 2 duas las. https://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=A26513-40-NDSame yam ntawm Sparkfunhttps://www.sparkfun.com/commerce/product_info.php? products_id = 116 Cov no yog cov txiv neej ncaj ncaj headers tus pin Koj tuaj yeem siv theoretically siv lub kaum sab xis ib yam nkaus, tab sis kuv siv tus pin ncaj.

Kauj Ruam 2: Txiav cov Pins Koj Yuav Tsum Tau

Kuv tsuas xav tau nkag mus rau 7 ntawm 9 tus pin, yog li kuv tsuas yog ua 7 tus pin txuas. 8 tus pin yuav yooj yim rau ua ib yam nkaus, tab sis 9 tus pin yuav xav tau qee qhov kev hloov pauv vim tias nws tau so me ntsis los ntawm lwm qhov 8. Cut lub taub hau rau tus lej pin koj yuav siv. Koj yuav xav tau 3 txheej ntawm qhov ntev ntawd, rau kuv, 3x7 tus pin. Optional: ib ntawm kab yog ib yam li thaub qab rau daim npav. Nws yuav muaj peev xwm siv tsuas yog ob peb tus pin ntawm ntug es tsis siv kab puv, tab sis kuv tsis ua raws txoj hauv kev no. Cov txheej txheem yuav pib sib txawv nyob ib puag ncig theem 4, thaum koj txuas kab thib ob ntawm lub taub hau rau thawj. Yog tias koj tab tom ua lub kaum sab xis txuas, txoj cai lub taub hau taub hau tuaj yeem ua rau muaj txiaj ntsig zoo dua. Kuv siv tus pin ncaj rau kuv li cas los xij thiab nws ua haujlwm tau zoo txaus.

Kauj Ruam 3: Khoov Pins

Tam sim no koj muaj cov neeg sib cuag, lawv yuav tsum tau khoov kom ntseeg tau zoo thiab ntseeg tau kev sib cuag nrog daim npav. Nqa ib qho ntawm 3 kab ntawv kab taub hau thiab muab tso rau hauv lub vise, lossis ib khub pliers lossis vise grips. Kuv tuav qhov kawg ntawm cov pins kom lawv tsis txhob rub tawm ntawm cov yas. Ua siv rab koob lub qhov ntswg, khoov cov pins tsuas yog me ntsis ntawm lub hauv paus, kom qhov kawg ntawm tus pin yog hais txog ntsug nrog ntug ntawm cov yas. Saib cov duab kom ntxaws. Tsis yog txhua tus pins yuav tsum ua kom zoo sib xws. Khoov lawv txhua tus tawm tsam ib lub rooj lossis tiaj tiaj kom kab lawv zoo dua. Tam sim no lawv yuav tsum tau khoov rov qab ntawm lub ntsis kom nws yooj yim rau ntxig daim npav. Ib zaug ntxiv nrog rab koob lub qhov ntswg, tuav ib qho me me thiab khoov nws rov rau lwm qhov kev taw qhia. Ua qhov no rau txhua tus pins. Saib daim duab kom ntxaws.

Kauj Ruam 4: Txuas Kab Thib Ob Ib ntus

Kab thib ob ntawm lub taub hau yog qhov tsuas yog thaub qab. Peb tab tom ua kab ntawm cov pins kom qhov no ua haujlwm tau zoo dua, thiab yog li nws yog txoj haujlwm huv dua. Kuv siv cov hlaws me me ntawm cov kua nplaum kub ntawm txhua qhov kawg los tuav lawv ua ke, tab sis txhua txoj hauv kev uas tawm hauv qab ntawm cov pins nthuav tawm yuav ua haujlwm. Tom qab ntawd kuv muab lawv tso rau hauv lub qhov muag dua vim tias peb xav tau khoov lawv me ntsis. Yog li cov laug sib koom ua ke muaj zog dua thiab huv dua, peb yuav tsum khoov cov hauv qab pins me ntsis. Txoj kev no peb tsis ntim ntau qhov chaw nrog cov hlaws dai. Lob ob tus pin thiab nyem me ntsis, yog li cov pins nyob ze ua ke. Qhov no yuav txawv me ntsis thiab tsis tseem ceeb heev uas nws yog qhov tseeb.

Kauj ruam 5: Npaj rau Soldering

Yog tias koj tsuas muaj ob txhais tes zoo li kuv, koj yuav xav ua kom yooj yim tuav txhua yam tib lub sijhawm. Kuv pom tias yog tias kuv ua cov hlau lead, kuv tuaj yeem ua cov khoom sib txuas me me los tuav cov khoom ua ke raws li qhov kuv xav tau yam tsis siv kuv txhais tes. Kuv yuav tsum tuav tus laug thiab hlau ib yam. Tin cov kab ntawm kab kawg ntawm lub taub hau ntxiv rau ob kab uas yog lub qhov (socket).

Kauj Ruam 6: Nthuav Kab Lus Header Kawg

Ntawm no peb mus rau ntu kawg. Koj tuaj yeem xaiv ua ntsug lossis kaum sab xis ntawm qhov no. Tsuas yog qhov sib txawv hauv qhov koj yuav siv kab tom kawg ntawm. Kuv twv koj tuaj yeem ua qee lub kaum sab xis ib yam yog tias koj xav tau. Tuav kab kawg raws qhov koj xav tau. Siv cov hlau txuas, kov cov tinned ua thiab qhov me me ntawm cov laug uas twb muaj lawm yuav tsum tuav 2 daim ua ke. Ua kom tiav tag nrho lwm cov pob qij txha siv cov laug ntau dua, thiab tom qab ntawd ntxiv qee cov laug rau thawj qhov sib koom tes. Ntxiv me ntsis ntau dua li qhov tsim nyog kom ntseeg tau tias muaj kev ruaj khov, tab sis tsis ntau npaum li ua kom pob. Cov no yog cov txheej txheem ib nrab, tab sis koj yuav tsum tsis txhob siv qhov no rau txhua yam uas ua rau lub zog quab yuam ib yam. Koj tuaj yeem tshem cov kua nplaum kub los yog yam koj siv. Cov laug yog tuav cov ntu ua ke kom zoo. Nws tsuas yog ib ntus xwb.

Kauj Ruam 7: Ua Raws Koj Li Circuit Court

Thiab peb ua tiav. Tam sim no koj muaj daim npav SD daim npav uas ntsaws ncaj qha rau ntawm lub khob cij. Koj yuav ua dab tsi tam sim no? Kuv ua kuv li vim kuv tab tom tsim cov ntaub ntawv logger nrog kuv Arduino thiab Memsic accelerometer, tab sis qhov ua tau yog qhov kawg. Tsuas yog xyuas kom koj tsis txhob tawm tus pin 7 thiab 8, lub qhov (socket) tuaj yeem swb rau nws, yog li ceev faj.

Kauj ruam 8: Ntxiv

Tom qab kev sib tham me ntsis hauv cov lus thiab lwm qhov, Kuv tau siv txoj hauv kev ruaj khov ntxiv rau lub tswv yim no. Kuv tau pom tias los ntawm kev khoov tus pin tib yam rau ib kab ntawm kab lus sab xis thiab txuas qhov ntawd rau PCB lossis perfboard, koj muaj lub tiaj, muaj zog SD qhov (socket). Qhov no yog qhov zoo tshaj plaws rau qhov kawg ntawm Circuit Court, ib qho tawm ntawm kev cai lij choj, lossis cov qauv zoo uas tsis tau tos rau lub qhov kawg. Kuv pom zoo khoov tus pin me ntsis ntxiv hauv thawj kauj ruam kom ntseeg tau tias txhua tus tau ua kev sib cuag zoo. Khoov lawv rov me ntsis ntxiv hauv theem ob yog qhov zoo ib yam. Kuv tau ua txhua tus ib tus zuj zus nrog rab riam thiab tuav tus pin hauv visegrips lub sijhawm no. Ntxiv rau tsis muaj tus pin ntawm lub dav hlau rov qab uas tuaj yeem tiv thaiv qee yam! Qhov ntawd yeej tsis yog qhov zoo. Ua tsaug rau frollard rau lub tswv yim! Kuv kuj tau suav nrog pinout ntawm SD daim npav los ntawm kev thov. Nov yog kev pom zoo nrog cov pins. Daim npav SD muaj ob hom, SD thiab SPI. Qhov tshwj xeeb ntawm cov no tuaj yeem nrhiav tau yooj yim ntawm wikipedia's SD card nplooj ntawv. Txog rau Arduino, txawm li cas los xij, tsuas yog hom SPI tuaj yeem siv tau. Hom SPI tsuas yog siv tus pin 1-7, tawm ntawm qhov me me thiab qhov tso tawm (8 thiab 9). SD hom rov kho qee tus pin thiab siv tag nrho lawv. Nov yog tus pinout rau SPI hom:… _._._._._._._._._…/… 1.2.3.4.5.6.7.8 |/.. 9 …………………… _ | 1 - Chip Xaiv*2 - Cov Ntaub Ntawv Input*3 - Ground4 - 3V35 - Moos*6 - Ground7 - Cov Ntaub Ntawv Tso Tawm*8 - NC9 - NC*cov no yog kab 3.3V logic. Txhua yam tab sis 7 yog cov ntaub ntawv nkag mus rau daim npav, thiab yog li yuav tsum tau nqis los rau 3.3V los ntawm 5V thaum siv Arduino Duemillenove. 7 yog qhov tso tawm, thiab Arduino tuaj yeem lees paub 3.3V siab, yog li tsis muaj qhov hloov pauv hluav taws xob xav tau ntawm no. Wikipedia muaj qee cov ntaub ntawv zoo ntawm SD daim npav, https://en.wikipedia.org/wiki/Secure_Digital_cardand pinouts.ru muaj qhov sau zoo ntawm tus pinout,
