Hi,
actually when I learn something new I always try a toy game, most of the time 
does not make sense but is fun.

I want to understand how to use those lovely connectors my telosb has so I have 
two toy games in mind.

a. If I understand it right these pins can give as output 3volts peaks and same 
for inputs. In that case I will connect to the right pins a 3volt led and make 
it lid.

b. Find an external sensor connect it and try to get the values I need.

I guess that a is far simpler than b but still I need some ways to get me 
started

Regards
A

First it would be more better if you explain what you mean by a "3 voltage" 
thing.   Do you mean tri-state?  If so please use the right term.   

Anyway, GeneralIO is very well described in two places.   The first is TEP117, 
Low-Level I/O, and the second is the source code.

When I'm looking for things I use stuff like…

    find . -iname "*generalio*"

when looking for what files have some thing to do with the name GeneralIO  or

    grep -nHiR generalio .

when looking for what files use GeneralIO.   The last will produce lots of 
output.



 
Any guide to start with?

sure.  look at the TEPS.   Look at the tutorials, to see if they touch on any 
of the problem you are messing with.

docs.tinyos.net

do google searching.


The more you help yourself, the more other folks will be willing to help you 
too.
