hi, i made a small programm wich blink a few seconds go to sleep mode the if waked up blink a few second etc...
that s my code:
digitalWrite(2,LOW); //for pull down
set_sleep_mode(SLEEP_MODE_PWR_DOWN);//set sleep parameters
digitalWrite(2,LOW); //for pull down again (to be sure)
it doesn't work neither for CHANGES or FALLING (after inversing pull down by pull up)
But it does work perfectly with LOW and the pull down in pull up...
It's a minipro mega168 5v 16mhz
i have no more ideas...
all the 4 kind of interrupt work perfectly on my uno...
