Arduino® yog dab tsi
Arduino ® yog qhov qhib-qhov kev tsim tawm platform raws li cov khoom siv yooj yim siv thiab software. Arduino ® boards muaj peev xwm nyeem tau inputs - lub teeb-on sensor, ib tug ntiv tes ntawm ib tug khawm los yog ib tug Twitter lus - thiab tig nws mus rau hauv cov zis - ua kom lub cev muaj zog, tig rau ib tug LED, tshaj tawm ib yam dab tsi hauv internet. Koj tuaj yeem qhia koj lub rooj tsavxwm yuav ua li cas los ntawm kev xa cov lus qhia rau lub microcontroller ntawm lub rooj tsavxwm. Txhawm rau ua li ntawd, koj siv Arduino programming lus (raws li Wiring) thiab Arduino ® software IDE (raws li Kev Ua Haujlwm). Ntxiv ntaub thaiv npog/modules/components yuav tsum tau nyeem cov lus twitter lossis tshaj tawm hauv online. Surf rau www.arduino.cc yog xav paub ntxiv.
Khoom dhau lawmview
Cov ntaub thaiv npog no yuav ua pov thawj muaj txiaj ntsig rau kev sau cov ntaub ntawv nrog koj Arduino®. Yuav tau yooj yim sib sau ua ke thiab kho kom haum rau txhua qhov project data-logging project.
Koj tuaj yeem siv daim npav no nkag mus rau microSD daim npav nco siv SPI raws tu qauv hauv koj cov haujlwm microcontroller.

Kev ua haujlwm
Taw qhia
WPI304N SD daim npav module yog tshwj xeeb tshaj yog pab tau rau tej yaam num uas yuav tsum tau cov ntaub ntawv logging.Arduino ® muaj peev xwm tsim ib tug file mus rau ib daim npav SD los sau thiab khaws cov ntaub ntawv, siv lub tandard SD tsev qiv ntawv los ntawm Arduino ® IDE. WPI304N module siv SPI kev sib txuas lus raws tu qauv.
Npaj daim npav microSD
Thawj kauj ruam thaum siv WPI304N SD daim npav module nrog Arduino ® , yog formatting microSD daim npav li FAT16 lossis FAT32 file qhov system. Ua raws li cov lus qhia hauv qab no:
- Ntxig SD daim npav hauv koj lub computer. Mus rau My Computer thiab right-click rau SD card tshem tau tsav. Xaiv hom raws li qhia hauv daim duab hauv qab no.
- Lub qhov rais tshiab pops. Xaiv FAT32, nias Start kom pib cov txheej txheem formatting thiab ua raws li cov lus qhia ntawm lub vijtsam.
Siv SD daim npav module
Ntxig lub formatted microSD daim npav hauv SD daim npav module. Txuas lub SD daim npav module rau Arduino ® Uno raws li qhia hauv Circuit Court hauv qab no, lossis kos lub rooj ua haujlwm tus pin hauv ntu dhau los.
Coding
Cov ntaub ntawv SD daim npav
Txhawm rau kom paub tseeb tias txhua yam txuas tau raug, thiab SD daim npav ua haujlwm, mus rau File → Examples → SD → CardInfo hauv Arduino ® IDE software.
Tam sim no, xa cov lej rau koj lub rooj tsav xwm Arduino® Uno. Nco ntsoov xaiv lub rooj tsavxwm thiab COM chaw nres nkoj. Qhib lub serial saib nrog baud tus nqi 9600. Feem ntau, koj cov ntaub ntawv microSD daim npav yuav raug nthuav tawm hauv cov saib xyuas. Yog tias txhua yam ua haujlwm zoo, koj yuav pom cov lus zoo sib xws ntawm cov saib serial.
Nyeem thiab sau cov ntaub ntawv rau hauv daim npav microSD
Lub tsev qiv ntawv SD muab cov haujlwm muaj txiaj ntsig uas tso cai rau sau tau yooj yim thiab nyeem los ntawm SD daim npav. Qhib ReadWrite examplwm od File → Examples → SD → ReadWrite thiab xa nws mus rau koj lub rooj tsav xwm Arduino® Uno.
