[Tinyos-help] Accessing MAC Layer Events from Application

[Jim Fell]

Hello.  I'm attempting to toggle a port pin whenever a packet is
received or sent by utilizing the MAC layer events.  However, when I add
these events to my application, even though it compiles, I do not seen
the pins toggling on my oscilloscope.  I've been able to verify that the
functions I'm using the toggle the pins work.  So, I can only guess that
I may not be setting up the wiring to the events properly.  Here's what
I have so far.  Any insight would be appreciated.  Thanks.
