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.Â 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 :)
