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;
• Uniformed 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

• Using adfaruit SD library：
  • Original library:（core+ can't use it directly）【github download】
  • Changed libray：（For the spi pin of core+, do some change)【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

Test program：File:Program Test SD.zip

Microduino-SD file read,write,delete test

• Prepared hardware：Microduino FT232R、Microduino Core、Microduino SD；
• Prepared software：Microduino provides test program（Arduino part）、Arduino IDE（1.0 release and upper）、SD library;
• Put the downloaded library to the libraries folder of Arduino IDE installation;
• Start Arduino IDE，open the test program,board type chosse "Microduino Core (Atmega328P@16M,5V)",download directly；
• Totally four parts，using the OLED to check（If no OLED, you can suse serial monitor):
  • CS pin match
  • Wirte data to SD card；
  • Read specified file's data from SD card；
  • Delete file from SD card。
