Microduino-SD

Microduino-SD aims to read and write data of a memory card.

Features

• Adopt high reliable contact structure as well as a 2.2mm or 2.4mm-thick microsd card holder;
• Small, cheap, stackable and open;
• Open hardware circuit design and Arduino compatible programming development environment;
• Uniform Microduino interface standard and rich peripheral modules, capable of having a fast and flexible connection and extension with other modules and sensors in accord with Microduino interface standard;
• Easy to be integrated to pegboards with a 2.45-pitch female header connector interface.

Specifications

• The memory card it supports：MicroSD（TF）；

Document

Eagle PCB File:Microduino-SD.zip

Main components

• Card holder：microsd File:MicroSD.pdf
• Level conversion chip：TC74HC4050 File:TC74HC4050AF.pdf

Development

Arduino library and supported package

• Adopt adfaruit SD library：
  • Original library:（Core+ can't be used directly）【github download】
  • Changed libray：（The spi pin of Core+ has been changed)【File:Lib SD.zip】
  • SimpleSDAudio:https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Libraries/_06_Microduino_SD_SimpleSDAudio
• Microduino core module can be combined with the sensor module to store and read data,and then analyze, process these data.

Application

Program Download

Program test：File:Program Test SD.zip

Microduino-SD file read,write,delete test

• All hardware needed: Microduino FT232R, Microduino Core and Microduino SD;
• All software needed: Microduino test program(Arduino terminal), Arduino IDE(version 1.0 and higher) and SD library;
• Put all the download library file into the libraries of Arduino IDE installation folder;
• Start Arduino IED, open Microduino test program and choose Microduino Core(Atmega328p@15M,5V), then download;
• Below are four parts, which can be checked with OLED(If you don't have OLED, you can check with the serial monitor):
  • Check whether the CS pin is ok
  • Write data into SD card;
  • Read out the data of the specified file inside SD card;
  • Delete the specified file inside SD card;
