Linda, <br><br>Thanks for sending this on to me. I forgot I sent it from your email... :-)<br><br>Arjun,<br><br>I'm in the Seattle area, and would love to work with you on the OLPC. I have worked with python and unix, so I might be of some help. Let me know how we can best work together. Thanks,<br>

Ray,<br>
<br>
Thanks for your message.<br>
<br>
As I understand, that you wish to connect multiple sensors to the USB<br>
based sensor board and from the UI of your activity/application<br>
select which sensor to read from.<br>
<br>
Edward Baafi, cced here might be able to comment better on that since<br>
he's been most deeply involved in the programming of the USB based<br>
sensor board.<br>
It would be a matter of writing a simple python script that would<br>
involve making use of the pyusb python libraries.<br>
<br>
I would like to point out at this point that USB based sensor board<br>
support hasn't yet been incorporated into Measure yet, though I do<br>
have plans of doing that. Any help by anyone in this regard would be<br>
greatly welcome as I develop Measure from whatever free time I get<br>
from school studies.<br>
<br>
many thanks<br>
Arjun<br>

Arjun,<br>

I'm just getting started working with my XO, and I built a temperature<br>
sensor with an LM35 chip. My intention is to have multiple sensors around<br>
the house, and read each of them separately. I am puzzling over how best to<br>
output a binary code to select which sensor I wish to read. I know that the<br>
USB port and the USB card that is being designed (and produced?) will allow<br>
me to communicate out from the XO, but is there some other way that I'm not<br>
thinking of that could be used?<br>
<br>
I like it that I can get analog data into the XO so easily. Now I'd like to<br>
know how to get digital data out effectively.<br>
<br>
Thanks,<br>
<br>
