The design document has been given its final official
revision of the semester. The
schematics for the hardware are now available for download in the "Download" section, as well as
source code for the learning software and the PIC. Some pictures of the test results are also
available for download in the "Download" section. I will
sleep now...

This was a good week. Nathan made great progress with the pitch detection. Jerry got the mixing
circuits to work. Alex added more MIDI functions to the PIC, and I finished the grading algorithm.
We'll have the latest software uploaded by next week. We will also have some simulations and graphs
and our first draft of the final presentation. According to the MS Project file, we are 81% finished
with the prototype.

The MIDI interface software correctly reads from the MIDI port and stores the data
into a file. The early A/D circuitry has been simulated with satisfactory results at high frequencies, but
not as well at low frequencies. Nathan has ported the old C++ code to the new chip successfully.
I have written some C++ code for the MCU to output MIDI pitchwheel and volume messages similar
to how it will be done in the final product. I have also uploaded some more files to the "Downloads" section.

The goals for this coming week include the following:
PC program reads and stores data
from the MIDI port and compare results to a pregenerated file
"Theremin" circuitry for demonstration using new parts
Develop LCD code for the MCU that displays information
Begin developing testing methods for A/D conversion
Update MS Project information

Dan and I have flushed the old C++ code down the drain. It was taking us too
much time to learn how to display our information on the screen. We decided
to go with Microsoft Visual Basic instead. It is much easier for us to implement
graphical content using this software. It took Dan 2-3 hours to redo all the work that
had taken us 2 weeks to do. We have also added additional functionality as
well. It now displays note, volume, and duration information of MIDI files on
channel 0.

I added the grand design of our project to the "Abstract"
section, be sure to check it out if you haven't a clue what
a Theremin is, or if you just like to read. I also added my
ugly mug to the members section and made some various cosmetic
touch-ups to the site.

I included the latest version of the Theremin Learning software under the downloads
page. It is capable of opening a new dialog box that plays a midi file. The play and stop
buttons also work now. The next step is to inherit the open dialog box functionality to
allow it to play any midi file. This week, Dan and I will be working hard to get the program
to display the current note's pitch and volume information for use later.

The latest revisions to the Design document and the product brochure are available
in the status section. The biggest change was Jerry's
overhaul of the problem statement. Pictures, detailed
task lists, schematic designs, and
source code for a working window were also made last week. All of these will
be made public on the website.

Our product brochure is now in the Status section. Not too fancy,
just a rough sketch of what our project might look like, and some specifications.
We talked to Dr. Resse a few days ago to get some feedback on
our project. He suggested testing the algorithms we plan to
use on our MCU on a PC first. This will give us an idea of the
speed at which we need to run the controller.
So there should be some source code and data coming soon dealing with that.

The website is up and running. Look here for relevant information
that the team members feel like posting. Any problems on the
site can be sent to me Nathan
(ntp1@msstate.edu) .
The deliverables can be found on the "Project
status" page.
