Yintoni iArduino®

I-Arduino ® yiplatifomu yeprototyping evulekileyo esekelwe kwi-hardware ekulula ukuyisebenzisa kunye nesofthiwe. Iibhodi ze-Arduino ® ziyakwazi ukufunda amagalelo - inzwa yokukhanya, umnwe kwiqhosha okanye umyalezo we-Twitter - kwaye uyiguqule ibe yimveliso - ukuvuselela i-motor, ukuguqula i-LED, ukupapasha into ethile kwi-intanethi. Ungayixelela ibhodi yakho ukuba yenze ntoni ngokuthumela isethi yemiyalelo kwi-microcontroller ebhodini. Ukwenza njalo, usebenzisa ulwimi lweprogram ye-Arduino (esekelwe kwi-Wiring) kunye ne-Arduino ® software ye-IDE (esekelwe kwi-Processing). Izikhuselo ezongezelelweyo/iimodyuli/iinxalenye ziyafuneka ukuze ufunde umyalezo we-twitter okanye upapashe kwi-intanethi. Sefa ukuya www.arduino.cc ngolwazi oluthe kratya.

Imveliso iphelileview

Eli khaka liya kuba luncedo ekulobeni idatha ngeArduino® yakho. Inokudityaniswa ngokulula kwaye yenziwe ngokwezifiso kuyo nayiphi na iprojekthi yokuloga idatha.
Ungasebenzisa eli khadi ukufikelela kwimemori khadi ye-microSD usebenzisa i-SPI iprothokholi kwiiprojekthi zakho ze-microcontroller.

Ukusebenza

Intshayelelo
Imodyuli yekhadi le-SDI ye-WPI304N iluncedo ngakumbi kwiiprojekthi ezifuna ukungena kwedatha.I-Arduino ® inokudala file kwikhadi le-SD ukubhala nokugcina idatha, usebenzisa umgangatho SD ilayibrari evela Arduino ® IDE. Imodyuli yeWPI304N isebenzisa iprotocol yonxibelelwano lweSPI.
Ukulungisa ikhadi le-microSD
Isinyathelo sokuqala xa usebenzisa i-WPI304N imodyuli yekhadi le-SD kunye ne-Arduino ®, ukufomatha ikhadi le-microSD njenge-FAT16 okanye i-FAT32. file inkqubo. Landela le miyalelo ingezantsi:

Faka ikhadi le-SD kwikhompyuter yakho. Yiya kwikhompyuter yam kwaye ucofe ekunene kwikhadi le-SD elisusekayo drive. Khetha ukuFomatha njengoko kubonisiwe kumfanekiso ongezantsi.
Ifestile entsha iyavela. Khetha i-FAT32, cofa u-Qalisa ukuze uqalise inkqubo yokufomatha kwaye ulandele imiyalelo yesikrini.

Ukusebenzisa imodyuli yekhadi le-SD
Faka ikhadi le-microSD elifomathiweyo kwimodyuli yekhadi le-SD. Qhagamshela imodyuli yekhadi le-SD kwi-Arduino ® Uno njengoko kubonisiwe kwisekethe engezantsi, okanye khangela i-pin assignment table kwicandelo langaphambili.

Ukufakwa kweekhowudi
Ulwazi ngekhadi le-SD
Ukuqinisekisa ukuba yonke into ifakwe ngokuchanekileyo, kwaye ikhadi le-SD liyasebenza, yiya ku File →Eksampngaphantsi → SD → CardInfo kwi-software ye-Arduino ® IDE.
Ngoku, faka ikhowudi kwibhodi yakho yeArduino® Uno. Qinisekisa ukuba ukhethe ibhodi efanelekileyo kunye ne-COM port. Vula i-serial monitor ngereyithi ye-baud 9600. Ngokwesiqhelo, ulwazi lwekhadi lakho le-microSD liya kuboniswa kwimonitha yothotho. Ukuba yonke into isebenza kakuhle, uya kubona umyalezo ofanayo kwimonitha yothotho.

Ukufunda nokubhala idatha kwikhadi le-microSD
Ithala leencwadi le-SD libonelela ngemisebenzi eluncedo evumela ukuba ubhale ngokulula kwaye ufunde kwikhadi le-SD. Vula i-ReadWrite example ukusuka File → Eksampkancinci → SD → FundaBhala kwaye uyilayishe kwibhodi yakho yeArduino® Uno.

Nje ukuba ikhowudi ilayishwe kwaye yonke into ilungile, le festile ilandelayo ibonakala kwimonitha yothotho.Oku kubonisa ukuba ukufunda/ukubhala kube yimpumelelo. Ukujonga malunga ne files kwikhadi le-SD, sebenzisa i-Notepad ukuvula i-TEST.TXT file kwikhadi le-microSD. Idatha elandelayo ivela ngefomathi ye-.txt:
