Posting the question here is fine.

But... we need to know what the keypad structure is, what an "O-sub LED" is and most importantly for assembly language, what processor you are using.

I am using a atmega32a for the processor. an ousb is just a board just like a arduino with 8 LEDs on it. I provided a photo of the keypad and the OUSB.
for the board, it had 8 LEDs on the left side, they are supposed to display the number I press on the keypad.

please let me know if you need anything else.
