Hi, i'm just approaching to the tinyos' world! i want to know how i can generate a 40 khz square wave on a IRIS mote, simply switchin on and off a genealIO port. I succeed in driving and switching portA (B,C etc) of the iris' Atmega1281 using HplAtm128GeneralIOC component; the problem is that i'm using TimerMilliC as timer and it seems doesn't work with a microtimer granurality.
any suggestion? How can i use microtimer to switch a digital port(pin) every 25 microseconds ca.?
