digitalPulse and setTimeout doesn't work

Hi,

I'm trying to write a simple LED animation for a 7-segment display. It will light up a segment, then another one, then another one, until all are lit up, then dim a segment, then dim another one, etc. The code is (supposed to be) very simple. For reference, I'm using an MDBT42Q module with a 32khz crystal added on P0 and P1 with 22pf caps. I don't think it should affect my code.

var segs = [A, B, C, D, E, F]; // array of LED segments, each a variable for a pin

for (int i=0; i<6; i++) {
    digitalWrite(segs[i], 1); // light up the first segment in segs[]
    digitalPulse(D30, 0, 100); // pulse unused pin for 100ms, this is just a simple delay
}
for (int x=5; x>=0; x--) {
    digitalWrite(segs[i], 0);
    digitalPulse(D30, 0, 100);
}

and well, the code works as if the digitalPulse()es aren't even there. Everything happens very quickly so the LEDs just light up and off in a fraction of a second. I honestly have no idea why this isn't working as the other digitalPulses in the rest my code work just fine. I have other LED animations that use digitalPulse() in my code and those animations have no problem.

So I tried using setTimeout(). I believe it's like so, but I might be wrong:

  for (var i = 0; i<6; i++) {
    setTimeout('digitalWrite(segs[i], 0)', 100);
  }
  for (var x = 5; x>=0; x--) {
    setTimeout('digitalWrite(segs[x], 1)', 100);
  }

this one doesn't work either. So I tried another method:

digitalWrite(A, 1);
digitalPulse(D3, 0, 100);
digitalWrite(B, 1);
digitalPlulse(D3, 0, 100);
digitalWrite(C, 1);
digitalPulse(D3, 0, 100);
.
.
.

And same results.
This has been driving me absolutely bonkers for the past few hours so any help would be greatly appreciated!
