SD Memory Shield -Arduino Compatible
SD card is often used as a storage device such as in a digital camera, MP3 or GPS navigators. We can also use SD card to record the date when using Arduino. However, it’s not easy to let SD card and Arduino work together. The hardware connection is the first problem, then comes the software problems to read the data by other devices.
According to the demand of hardware, we have developed SD card module, it communicate with Arduino through the SPI interface.
At the same time, to connect the SPI interface with Arduino.
The circuit connection is “plug and play”. It uses six-core IDC connection wire to connect SPI socket on IDC board to the corresponding socket on SD card modules.
As to software, our goal is to make the data recorded in SD card be able to read on computers, So we need to follow certain rules to record the data to SD card, namely the file system type. As Arduino system is simple, FAT16 is a good choice.
Here we will use for SD card reader to make corresponding processing, It will be formatted into FAT file system:
The software used on Arduino is based on the library from SparkFun, but modified according to the difference of hardware. You can downloaded the modified FAT here. The library needs be uncompressed into “hardwarelibraries” subdirectory.
Please note that as the code used by SD card and file system is a little much, at present this modules can only work with Arduino of ATmega328P.
