Re: A83: Time


I assume you meant something like this:
  ld b,0
  ei
delay_loop:
  halt
  djnz delay_loop

Although actually since the interrupt runs at 200hz, you would need a larger 
timer if you want to be closer to 3 seconds.  Maybe something like this:
  ld bc,600
  ei
delay_loop:
  halt
  dec bc
  ld a,b
  or c
  jr nz,delay_loop


That should be a lot closer to 3 seconds.
