[Tinyos-help] TinyOS MICAz GpioInterrupt

[Andres Vahter]

I added following lines to boot.booted():

	call IO.makeInput();
	call IO.set();

	call Interrupt.disable();
	call Interrupt.clear();
	call Interrupt.edge(TRUE);
	call Interrupt.enable();

It seems that problem was that i didn't set the PortE4.
Now it works fine - interrupt is triggered when I connect wire from  
Int4 to Gnd.
Without IO.set() led toggles all the time when loose wire is connected  
to Int4.

I think I actually have to create a "driver" similar to Sensor Driver  
Example 2 (http://tinyos.cvs.sourceforge.net/*checkout*/tinyos/tinyos-2.x/doc/html/tep109.html 
)
I access directly to HplAtm128InterruptC. It seems from that example,  
that I should use GpioInterrupt interface instead.
