All of Port E (and most of A-G, except what is used on-board) is brought out on the 51 pin connector on mica devices. Presumably the IRIS uses the same layout. Here's my cheat: http://www.etantdonnes.com/Motes/ATMEGApins.txt Great that you know the timers! It sure would be nice to have TOS support for more of the micro-controller features. And to know which are already being used (I had to reverse engineer which Timers were used in T1...) I already ref'd my humble attempts at PWM and Capture in this thread if it's of any use to you, see under Motes above...
