Interrupts

---

DUELink Engine can invoke a function when a pin changes, on interrupts. IStart(func, pin, trigger, pull) where trigger is: 0- Falling edge, 1- Rising edge, and 2- Falling & Rising edges. Pull is: 0- none, 1- up, 2- down.

_i = 450
_b = 0
IStart("Blink", 1, 0, 1)

while 1
  PrintLn("Stat: ", Istatled("Blink"))
  Wait(100)
wend

fn Blink()
  DWrite(0, _b&1)# Status LED is always on pin 0
  _b=_b+1
  println("Blink: ", _b)
  if _b=100# stop the interrupt after 100
    IAbort("Blink")
  end
