Assembler language program help

[Mark_76]

maxbotix.com EZ0 sensor

Above is a simple distance sensor I bought.
I want to turn on LED's for a distance to a wall "proximity warning device".

RED = stop!
Amber = Warning prepare to stop
Green = ok to drive

I will simulate using a Dragon 12+ plus microcontroller board and debug 12.

I need code for this in Assembler language.

Note:
Once I have it I want to consider sounds such that:
RED led = constant warning chime
Yellow = slow beep
Green = no beep
Flashing red LED = you are closer than 1.0 feet to a wall and are about to hit.

I will use the AN analog o/p of the maxbotix sensor.
The device turns out a voltage corresponding to the distance.

So, when you are at 5 feet or greater from a wall we should turn on a green LED.

If we are at 2.5 to 4.9 feet we should turn on a Yellow led.

If we are at 2.4 feet to 1.5 feet = red.

I have the idea that anything under 1.4 to 0 feet should flash a red led!!!

This is a simulation I am doing.


Does anyone know how to go about illuminating external LED's that are breadboarded onto the Dragon 12+ microcontroller?
It is NOT codewarrior so I have been having difficulty finding any example scripts.
It is in Debug 12, 68hcs12, Assembler language prgramming.

1st screen
The 1st frame nid to be clicakble to do the 2 screen frame
example if u click the a,d,d,i.t,i,o,n any of the letters we going to second frame to do the operation the same in subtraction and multiplication but the division nid a two answer the quotient and remainder

1st number___
2nd number___
result___
press any key 2 return to menu
second screen
note 3 digits max including negative value and the numbers be in ascii code...

pls help me..tnx
