Furthermore, SD card initialization, data reading, data writing, and data erasing, were
explained. The information was extremely similar to what we are doing for our project (based of
off Terasic’s demo.) and multiple example projects we have found have used the same methods
for SD card communication (1-bit SPI). Most examples only did reading, so the data writing and
data erasing details could possibly be utilized for further functional expansion of our guitar
gloves.

In our project, we are playing sound files from the SD card to the audio codec, and the
transmission is realized by I2C bus. This article provides the information about how to realize
communication by using I2C bus in DE2 board. It explains how I2C controller work in detail by
commenting the verilog codes provided by Altera. Thus this article is really helpful for us to
understand the functionality, and performance of I2C bus so that we can embed our
accelerometer into our design.
