SD HSMCI for the Arduino Due

Firmware for Arduino Due SD HSMCI Card. Pin wiring set for the PowerDué. Reference for PowerDué lab for Low Power System on Chip Spring 2016 at CMU-SV.

Install

  1. Download the files
  2. Move the folder Arduino_Due_SD_HSMCI to your Arduino Libraries
  3. Move the folder SD_HSMCI to your Arduino Libraries (Same level as Arduino_Due_SD_HSMCI)

Storage manipulation

  • The SD object will be created on #include <Arduino_Due_SD_HSMCI.h>
  • Use SD.MakeDirectory to create a directory

Creating a file

  • Create a new FileStore with FileStore * f = new FileStore()
  • Initiate the File pointer with f->Init()
  • Open the File Structure with f->Open([DIRECTORY], [FILENAME], [FILE_WRITE | FILE_READ])
  • Write with f->Write([BUFFER], [LENGHT]);
  • Close f->Close()

Arduino Wiring
