Hi,

Two Function Calculator

I am designing  and synthesizing a calculator on the DE-1 board that can 
add and subtract integers. I want to Interface to a small 12-key keypad
interface to a standard VGA display.
Enter numbers via the keypad.  I am basically looking to use buttons on 
the DE-1 board and display the numbers and the result on the display. I 
guess a low resolution, monochrome characters are sufficient. I am 
having trouble writing the interface part of the display.

Any help regarding this or a example template or anythign to do with 
this would help me in understanding much better.

thank you :)

Did you try "VGA interface VHDL" or "VGA interface Verilog" on google?
