Proton + application program to PORTC KEYPAD_PORT command?

[vasili35]

Proton + Program "KEYPAD_PORT = PORTB" command using the keypad and works in PORTB. but if we have to attach the keypad, the command will be the other ports .. I "KEYPAD_PORT = PORTC" doing everything mixed up .. but you have an idea of the ?

Your question is not clear. Post your circuit schematic (eq Proteus DSN) and your program here.

Because PORTB has internal pullups but PORTC doesn't.
Attached the modified working project (your lookup table is also modified by me).
Good luck.
PS:
I'm using Proton PDS 3.4.0.8 and Proteus v7.7sp2
