re: while

[pete]

Hi there!
I want to receive a 1ms pulse received from x10 power line interface receiver. This pulse occurs within 200us of a 60hz digital zero crossing input to a PIC pin RB0. Input data pin is RB1.

If I use

while(input(PIN_B0)) //zero crossing
{ <--what delay is needed here?
h1=input(PIN_B1);
<--what delay is needed here?
h2=input(PIN_B1);
<--what delay is needed here?
h3=input(PIN_B1);
.
.
.
}
My question is: will input to B1 be successively filled up h1, h2 and h3, etc.. of the bits received for every zero crossing? Or does the "while" allows filling-up of B1 values while pin B0 is high. What i need is, filling up of h's values be done only after each zero crossing...

Your kind help is appreciated...Thanks.

there are tons of X10/pic examples on the web.
