hi t,i'm trying to count pulses using my AVR.
but i'm not sure how to accomplish that.
I was thinking of using timer interrupt using the same frequency as the pulses.
any idea?
hi eric,hi t,
Does the AVR have an 'interrupt on change pin' function.?
hi,hi eric,
i'm not sure if you are referring to this?
in actual fact, i want to detect the phone rings.hi,
I would say low level INT2.
What is the maximum counting rate you require.?
