You write the numbers to a port in sequence.

To do that you can send the data directly to the port:

like

MOV Px,#your first data
MOV Px,#your second data

etc

But this will be very fast and not particularly pretty ! The next step is to write delay code that holds up your sequence for a second or so per step perhaps. You can do that by the quick and dirty method

timeblock:

MOV r2,#128
MOV r3,#64
Loop1:nop
loop2:DJNZ r3,loop2
DJNZ r2,loop1
RET


Here the inner loop counts down from 64 before the outer loop counts 128 lots of 64, playing with the numbers will tune the speed to your crystal and hardware, but change the crystal changes the timings, and the whole processor stops doing other stuff to just sit on its ass and wait.


Now your code is
MAIN:
MOV Px,#first number
Acall timeblock
MOV Px,#second number
Acall timeblock
.
.
.
.
.
JMP main


The next step is to use the onboard timers, but thats for another (brief) lesson

You really need to list the numbers in a little table
