project status

[James Horey]

Hello everybody that will be reading this,

I realize this is a slightly early status report, but I'm going on vacation 
for a few days and this is the best chance I'll get to write this. Also, this 
particular status report is going to be on what I've been doing for the past 
few weeks (about 2.5 weeks or so) instead of just last week. Now on to the 
actual status...

During the first week I quickly learned Ruby and some various Qt programming 
concepts. Once I had a handle on these tools, I wrote a simple GUI program 
that launched and connected to KSpread via DCOP to control reading/writing to 
cells and sheets. The DCOP interface is sufficient enough so that this code 
will form a basis for the initial data communication.

The second week was mostly spent on getting serial communication in Ruby to 
work with the sensor hardware (Mica2). I was able to get the Mica2's to 
collect sensor data and transfer this data over serial. I wrote Ruby code to 
convert the raw serial values into meaningful engineering values and 
automatically display them in KSpread. I also wrote code to send 
data/commands to the motes over serial. As of right now, I have reliable 
two-way communication between the mote and PC. 

Next week (or at least once I get back from vacation) will be mostly focused 
on designing and writing a simple "query processor". This will be code that 
will run on the sensor hardware that takes queries (objects produced by pivot 
tables) and uses the query to collect and extract the correct data and 
eventually produce a query response. I will initially write a simulated query 
processor in Ruby for debugging purposes and then port it NesC to run on the 
actual motes.

-James
