Try this:
component ServoPStart "This component is part of a parport
interface to an AVR ATtiny2313.(2010/11/05 kwall...@wallacecompany.com)";
pin out bit ServoStart "This is the output which goes high for one
period at the input toggle.";
pin out bit strobe "foobar";
pin out unsigned PCount=0 "";
//variable unsigned PCount=0; // Holds the number of periods since
the toggle.
//SCount variable counts how many times the counter function is called
variable unsigned SCount=0;
function dostrobe nofp;
function docount nofp;
license "GPL";
;;
FUNCTION(docount) {
if (SCount) SCount--; //tick
}
FUNCTION(dostrobe) {
strobe=0;
ServoStart=0;
if (SCount) return;
if (PCount==0) ServoStart=1;
if (++PCount>=3) { //tack
//foobar
strobe=1;
//reset
SCount=10;
PCount=0;
}
}
