Infinity Mirror

Abstact

In this project our main aim to build an embedded system based Music System that also displays 7 bands of frequency spectrum on an (64*64) LED display. The mp3 system plays music through a speaker interfaced with the board. It deals with the convergence of various services. Various services like gesture recognition, audio decoding, audio saving and retrieving, mirroring visualisation etc. are used and offered on this device. This project consists of ‘Audio Codec’ ‘RGB LED Matrix’ & 'HC-05' along with some other onboard features ‘Gesture detection’ ‘Ambient Light Sensing’ and ‘OLED Display’ with sj-two Launch pad. Audio Codec BP is connected to audio related peripherals.

Objectives

     1. Audio Codec - Interacting with Audio Codec for getting the sound samples & generating sound signals from the device
     2. Gesture Sensor - Detects the Hand Gesture and send the detected gesture to LED Matrix to navigate LED's.
     3. SD Card - Audio data or mp3 files will be retrieved from the SD card based on the user selection.
     4. Audio Decoder - Intelligently processing the audio data using audio decoder and sent to the LED Matrix to display spectrum patterns.
     5. Bluetooth HC-05 - Interfaces the system using Bluetooth to an Android application. 

Team Objectives

     1. Learn each and every module as much as possible, in order to develop an industrial product.
     2. Achieve 100% code coverage, during unit testing. 
     3. Document and track all the bugs encountered during development, unit testing, and field testing.

Printed Circuit Board

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:

Bug/issue name

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

• 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.
