Integrate the PmodKYPD into calculator

[riostarter]

Hi,

I am trying to integrate my Pmod KYPD into a basic calculator. I have made a VI (keypad interfacing) that reads the input buttons from the keypad into labview, but only the buttons. I like this code (calculator 2013) I found of a basic calculator function from LanxiZ, https://forums.ni.com/t5/Example-Code/Mini-Calculator-in-LabVIEW/ta-p/3516347. However, this code is strictly software. I have been trying diligently getting these two codes to work together with my Pmod KYPD. Any ideas or feedback is appreciated!

Thanks

Which buttons are you planning to use for  +   -   x   ÷   =   keys?

[riostarter]

A for division. B for multiply. C for subtraction. D for addition. E for enter. F for clear.

replace the software buttons with hardware buttons in the code.

If this is a class project, you should be doing the work.
