simple calculator assembly code

I need a basic assembly code with this description #### Description Implement a caluculator using Code Warrior, the Dragon 12, and the Wytec 4X4 keypads. The calculator should be capable of performing addition, subtraction, multiplication, and division on two one-digit values entered using the keypad. The resulting value can be positive or negative and up to two digits. #### Requirements/Notes * The LCD should display the decimal values as they are entered on the keypad, the function being peformed (+,-,*, or /), and the result. (eg, 2 + 6 = 8) * The keypads consist of numbers 0 through 9 and letters A through F. The numbers correspond to the decimal values. The "A" key will correspond to additon, "B" to subtraction, "C" to multiplication, "D" to division, "E" represents equals (the result should be calculated and displayed), and "F" when pressed should clear the display. * You will need to debounce your keypad so that glitches do not get mistaken for input values. Once a value is read, you should have a delay of about 100ms before scanning the keypad again. This should insure that the values are only read once. * Your Code Warrior project should be called "ee3176_project". You are free to name the source code programs, etc. as you wish, but give them descriptive names. Your code should be clearly written and well-commented (in order for me to understand and be able to explain whats going on) and should have a nice logical flow. It should be easy to follow for a programmer familiar with the hcs12 **As you can see I need to do this using the hcs12 board and build it in code warrior and use the dbug12 compiler. please help I need this as soon as possible!!!!!!!!!!!! ** ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform I need to use this using windows xp. Code Warrior, the Dragon 12,the dbug12 monitor(which isa software program that is burned into the Flash memory of the HCS12 chip and by default runs when the chip is first powered on. Using a serial communication program such as Hyperterminal, you can interact with D-Bug12 to use it for basic debugging.) and the Wytec 4X4 keypads
