Well, you know, the whole thing is called a _sensor_ network,
so basically the main point of the micro-controller is to attach
sensors to computers somehow...That said, there are not a whole
lot of examples, compared, say, to routing algorithms...
Look in the tos/sensorboards directories for some examples and
trace them back to the actual controller inputs that are used.
Mostly you'll find that the ADC and a few adhoc binary pins
have been implemented. Almost nothing for the counter/timer
pins, and as far as I can tell, el zippo for attaching stuff
by UART. There's a bit of noise on the list about SPI and I2C
and I guess some underlying code, but I haven't used it.
Over the last year or so I have handheld a number of projects
that wanted to connect things (like the CMUcam) via the UART,
and when the time came to get the grade many of them had something
working, but I never got a chunk of code out of it. One guy must
have been successful because he promised me a bottle of scotch
as a reward for his getting a degree. But I never got it...
Now that I have been a bit annoying, perhaps people will post
links to code and doc that I have missed, ignored, or forgotten.
I'm often tempted to flesh out the ATMEGA support myself, but
then again, why bother...

What about external digital devices to MicaZ? Use UART1?
Any example code in TinyOS 1.x? Thanks.

Subject: Re: [Tinyos-help] How to connect external sensors
look at the use of the ADC component(s), e.g., for mica's:
tinyos....\tos\platform\mica2\ADCC.nc and ADCControl.nc

Hi all,
i'm working with Tmote Sky modules; i want to connect external
sensor (for example pluviometer, anemometer) with the expansion
connectors on board on Tmote sky modules; I have to make software
connections, do you have developed components able to connect adc
interface to external sensor, for sampling from the analog connector?
what I have to do?
Thanx a lot
