Re: A92: Waiting for nokey?
Did you want to test when the keyboard is not being used? When no key is
being pressed? If so, here is the code that should do it. There may be
an easier way, but I haven't touched assembly for many months.
loop:
jsr flib[idle_loop]
cmp #264,d0 ;Esc or any
other key pushed?
beq done ;if so, goto
mentioned label
cmp #0,d0 ;if a key is not
pressed,
beq loop ;goto loop.
clr.l d0
bra loop Not sure if you need this or
not...
