microcontroller

I need a c program compatible with micro c compiler. The program needs to work between the microcontroller, stepper motor, lcd and keypad. The microcontroller is a pic16 and there are two stepper motors: (1) Astrosyn (23BB-H051-21) -- This is a 5V Dc stepper motor (6 coils)--this needs to move vertically up and down (2) Northland (1005-101) --this is a 1.8 degree motor that is 12VDC and needs to rotate 1.8 degrees each step. As specified the code should be compatible interface with the lcd, keypad: display Alpha Numeric. Once a numeric value is selected on the keypad (1,2,3,4,5,6) ,then according to that number, the lcd should display a certain alpha numeric value (the value will have no meaning, it's just for display) This program will be simulated in Proteus so once compiled in micro c , I will have to take the hex file and put it in the Proteus software to simulate. I need the code well commented. I will need this code in 3-4 days.
