[Tinyos-help] GPIO usage

[wolfgangmi]

Dear all,

I am using MICAz with TinyOS 1.1.15. I want to connect some general-purpose
I/Os on MICAz's processor to external hardware through the 51-pin connector
and read their values. My questions are:

1. What GPIOs in the 51-pin connector are available to users? Are INT0~INT3
fine?

2. How to read the value of a certain GPIO on the processor in nesC code? Is
there any existing library function to do this?

3. Where can I find the detailed form factor of the 51-pin connector and
where can I order these parts?

Thanks.

Regards,
Wolfgang
