As I've bought a Wattson - and starting to use the accompanying software (Holmes) to collect data - it's clear that the Wattson would be much more useful if I could get access to the data from my own software (I've got lots of ideas - more about that later).

And seeing the drivers they use to interface the Wattsons USB port to the Mac seems to be the same as I use for the Arduino, I kicked off Xterm (a terminal emulator) and attached the USB cable to the Wattson. With a little bit of experminatation it seemed that I got a echo from the Wattson if I set the interface speed to 192.000 bit/s.

The I fired up Holmes and the following text popped up in Xterm....

I exited Xterm, and fired up Holmes on it's own - and saw the following :

hm! It looks like the S003776 is the Wattson announcing its serial number to Holmes.

So in other words I have a start on finding out how the Wattson communicates with the computer - now the serious digging can start.

(All this would of course be unnecessary if DIY Kyoto released the protocol as promised (-;)
