High Level Design
SW & HW Design



The final product met our basic expectations.  We were able to record sound, play it back, and distort it.  If we were asked to do this project again, we would definitely not spend as much time on getting the SD card working.  Spending that much time on that part prevented us from trying new and interesting ideas, such as a DSP algorithm to store sound onto the memory.

For this project we looked at several drivers for getting the external memory working.  In the end we modified code by Terje Frostad.  There was no problem with this, since he had posted it online for this explicit purpose of helping people use DataFlash.


All ethical considerations were followed.  Relevant IEEE code of ethics points:

3. to be honest and realistic in stating claims or estimates based on available data;

   All information pertaining to this project is accurate.

4. to reject bribery in all its forms;

   We did not accept any bribes over the course of this project.

5. to improve the understanding of technology, its appropriate application, and potential


    This project gave us great project experience, and taught us appropriate application of

    particular hardware

7. to seek, accept, and offer honest criticism of technical work, to acknowledge and

    correct errors, and to credit properly the contributions of others;

    We have given credit where credit is due.

10. to assist colleagues and co-workers in their professional development and to support

      them in following this code of ethics.

      We offered help to anyone who asked for it.
