measuring time between two pulses

Hi all,

first time posting here. Ive got a most simple goal, measure the time between a bit going low and a second bit going low.

I can only use P1, so Im assuming

loop
while p1.0 = 1

p1.0 = 0?

start a timer, could count up to 10 seconds

now loop waiting for p1.1 = 0

p1.1 = 0?

stop the timer, calculate how many seconds

display the result. Im using an HTE SDK8032 board, there is a monitor routine to display text, it interfaces to hyperterminal. if I can just get that "seconds" value, I could convert as needed and print it.

simple. what happens? nothing.

now Im trying to use C and a 32bit long as the timer int, maybe decrement, jump not zero or ?

but figuring out time from the 11.05 Mc crystal (used for baud rates) is just not making sense right now, any help is appreciated.
