On page 10 of the Direct Commands.pdf, it talks about LS
communications on the NXT. Does anyone know what LS communications
are?
Also, in case anyone is interested, I'm working on a ruby module for
communicating with the NXT via bluetooth. It's pretty limited, but
you can see what I've done so far here:
http://juju.org/svn/public/ruby-nxt/trunk/
It makes programming the NXT as simple as:
require 'nxt.rb'
NXT.exec("/dev/tty.NXT-B") do |cmd|
puts "Battery Level: #{cmd.GetBatteryLevel[0]/1000.0} V"
cmd.PlaySoundFile(true,"Good Job.rso")
sleep(3)
cmd.StopSoundPlayback
end

LS is presumably Low Speed, which appears to map to the I2C serial comms
on each sensor port, pp9 & 10 of the Hardware Dev Kit.
Rather than the "High Speed" (HDK p8) balanced line (RS485) comms only
available on port 1, which has no protocol or driver currently
implemented. (One difficult bit is going to be assigning addresses.)

Sounds good. :-)

Oh, ok. So the LS commands would be used to access things like the
compass from mindsensors?

Looks logical to me, both the LS commands and I2C bus transfer up to 16
bytes at a time.
I am glad you asked about the LS commands, I had just flipped the page
before and not bothered to read the description. :-)
There are so many possible programs to start ...

The pdf docs are great, but having everything split up and in so many
files is making figuring things out a pain. It would be nice if we
put it all into a wiki or something to link all the info together in
an easier to read format. Maybe I'll start entering info into
http://www.nxt-mindstorms.com/wiki/Main_Page when I get the chance...
