SD Card Software

Overview

Micro-SD card

Ultimately, we want to be able to store configuration information about the Mega WiFi project on the built in Micro SD card. The WiFi Shield from Adafruit includes an SD Card interface which makes it very convienent to store information regarding the configuration of the device. In this section we will show you how to initialize communications with the SD card interface and read the contents of a file.

This file, called CONFIG.DAT contains configuration information for the WiFi shield. Information such as the SSID and encryption password are stored in this file. This save us from having to hard code the information in the sketch which makes the device more flexible. Eventually, we will also write information to the SD card as well for diagnostic purposes.

To run these programs you will need the following software:
