−	Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

	On startup, there is only one task that is created in main, namely the ultrasonic_sensor_task. This task reads the value that the ultrasonic sensor is sensing, and when the value is below 25, three tasks related to MP3 playback are created and begin running. There is a mp3_reader task, a mp3_player_task, and a mp3_contoller task. The controller task combs through the songlist and sends the name to the mp3_reader task to begin reading, and ultimately played. The reason this methodology was used was to make sure that the song title did not need to be hardcoded, so anyone could name their files whatever they wanted and the song would still play. The mp3_reader reads the data from an SD card to a buffer which will be transmitted to the mp3_player_task via a queue.

	=== LED Matrix Driver ===		=== LED Matrix Driver ===
		+	The LED matrix is controlled with a specific set of instructions. It functions by updating 2 rows of LEDs at a time, 1 in the first 32 rows and 1 in the second 32 rows. This type of scanning pattern occurs at a high enough frequency such that the human eye is unable to perceive the "scanning line" effect. The GIF below illustrates this effect.
		+	[[File:scan116.gif\|center]]
		+	In order to update the LED rows, you must do the following:
		+	# Disable the latch
		+	# Enable the output (keep in mind this signal is active low)
		+	# Use the RGB pins (R1, G2, etc) to set a color for a pixel in a row
		+	# Give a clock pulse to latch in the selected colors for each pixel in the row
		+	# Enable the latch to drive the LED driver
		+	# Disable the output
		+	The code in the following snippet will demonstrate the logic behind this functionality.

	Below you can find the coded implementation used to drive the LED Matrix based on the control method described in the above section.		Below you can find the coded implementation used to drive the LED Matrix based on the control method described in the above section.
