RE: A83: Delay Routine Need


If you use this delay routine, make sure to do a EI before calling...
otherwise your calc can hang...

  ei
  ld b,10
delay:
  halt
  djnz delay

Sprites are graphics and have no amount of "speed" associated with them 
unless you refer to a particular velocity for a character represented by a 
sprite...

If you want a delay routine, you can do something like this:

  ld b,10
delay:
  halt
  djnz delay


And the 10 can be varied depending on how long you want the delay to be.  If

it's a really short delay, use nop instead of halt.
