So the following should work to make it go from on through dim to off:

loop:
moveq #0,d0
move.w loop_val,d0

; on

loop2:
move.l d0,-(sp)
move.w #$25,-(sp)
trap #14 ;vsync
addq.w #2,sp
move.l (sp),d0
dbf d0,loop2

; off

addq.w #1.loop_val
cmp.w #255,loop_val
blt.s skip
move.w #255,loop_val
skip

bra loop

Message board and comments are now read-only

Due to abuse of the message boards we have put the entire site in read-only mode. That means you can't post new threads or reply to old messages and you can't add comments in VideoDB and PicDB.

Some messages have been erased from reading, but are stored in case they need to surface again.

After 17 years and 45000 messages we're shutting down due to one person.
