==MP3 Player with Graphic Equalizer Display==
 
 
 
== Abstract ==
 
The microcontroller (LPC1758) will read an MP3/Audio file from SD card then transmit the file to an audio decoder IC (VS1053). The audio decoder will play the file then output to a speaker or headphone. At the same time, the audio output also goes to an equalizer analyzing circuit using MSGEQ7 IC; the output of the equalize analyzing circuit will be input to the microcontroller (LPC1758), which will display different audio frequencies through an LED matrix.
 
 
 
== Objectives & Introduction ==
 
Show list of your objectives.  This section includes the high level details of your project.  You can write about the various sensors or peripherals you used to get your project completed.
 
 
 
=== Team Members & Responsibilities ===
 
*  Thinh Lu
 
** 
 
*  Brian Nguyen
 
** Construct MSGEQ7 circuits 
 
*  Andrew Pang
 
** Programming LED matrix
 
 
 
== Schedule ==
 
Show a simple table or figures that show your scheduled as planned before you started working on the project.  Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals.  The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

== Parts List & Cost ==
 
Give a simple list of the cost of your project broken down by components.  Do not write long stories here.
 
*(1) LED Matrix: $24.95
 
*(1) 12 V power supply: $11.59
 
*(20) jumper wires: $1.95
 
*(1) 4-pin Molex connector: $0.95
 
*(1) Electric tape roll: $0.95
 
*(1) Graphic equalizer display filter MSGEQ7: $4.95
 
 
 
== Design & Implementation ==
 
The design section can go over your hardware and software design.  Organize this section using sub-sections that go over your design and implementation.
 
 
 
=== Hardware Design ===
 
Discuss your hardware design here.  Show detailed schematics, and the interface here.
 
 
 
=== Hardware Interface ===
 
In this section, you can describe how your hardware communicates, such as which BUSes used.  You can discuss your driver implementation here, such that the '''Software Design''' section is isolated to talk about high level workings rather than inner working of your project.
 
 
 
=== Software Design ===
 
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. 
 
 
 
=== Implementation ===
 
This section includes implementation, but again, not the details, just the high level.  For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash.  You can include sub-sections for each of your component implementation.
 
 
 
== Testing & Technical Challenges ==
 
Describe the challenges of your project.  What advise would you give yourself or someone else if your project can be started from scratch again?
 
Make a smooth transition to testing section and described what it took to test your project.
 
 
 
Include sub-sections that list out a problem and solution, such as:
 
 
 
=== My Issue #1 ===
 
Discuss the issue and resolution.
 
 
 
== Conclusion ==
 
Conclude your project here.  You can recap your testing and problems.  You should address the "so what" part here to indicate what you ultimately learnt from this project.  How has this project increased your knowledge?
 
 
 
=== Project Video ===
 
Upload a video of your project and post the link here.
 
 
 
=== Project Source Code ===
 
*  [https://sourceforge.net/projects/sjsu/files/CmpE_SJSU_S2015/ Sourceforge Source Code Link]
 
 
 
== References ==
 
=== Acknowledgement ===
 
Any acknowledgement that you may wish to provide can be included here.
 
 
 
=== References Used ===
 
List any references used in project.
 
 
 
=== Appendix ===
 
You can list the references you used.
