mCookie-SD

mCookie-SD module is aimed at realizing the reading and writing to the storage card.

Features

• Adopt high reliability of contact structure, and 2.2mm and 2.4mm thick slim microsd cassette;
• Small, cheap, stackable and open;
• Open-source hardware circuit design, and copatible-with-Arduino programming development environment.

Specification

• Type of SD card supported：MicroSD（TF）；

• Level switching chip：TC74HC4050 File:TC74HC4050AF.pdf

Development

Arduino Library and Support Package

• Adopt adfaruit SD library file:
  • Primitive library:（core+ cannot be directly used）【github download 】
  • Modified library：（Spi pins have been modified aimed at core+）【File:Lib SD.zip】
  • SimpleSDAudio:_06_Microduino_SD_SimpleSDAudio

• YOu can store and read the date through combining Microduino core modules and sensors modules to realize memory, analysis, and processing.

Application

Program Download

Testing program：File:Program Test SD.zip

Test of Reading, Writing and Removing toward Microduino-SD Files

• Hardware needs to be prepare：Microduino FT232R、Microduino Core、Microduino SD；
• Software needs to be prepared：The testing programs （Arduino end）Microduino provides, Arduino IDE（Version 1.0 and above） and SD library；
• Put the downloaded library files into the libraries in Arduino IDE installation folder；
• Start Arduino IED, open the testing programs that Microduino provides, the board card choose Microduino Core (Atmega328P@16M,5V), and directly download；
• A total of four pieces, which can be checked coordinated with OLED（if you have not an OLED, you can use a serial port monitor to check）：
  • Whether CS pins can match it.
  • Write data to SD card；
  • Read the data of the specified files in SD；
  • Remove the specified files in SD card.
