3 buttons instead of the keypad
One to drive the value up (up arrow?), one to drive the value down (down arrow?), one to save the value and move on (enter?).
maybe even a 4th button to reset the value back to a default value (ESC?).
A lot easier than 'punching in numbers'.
Overdesigning a project sometimes really sucks...

Are you trying to use Mister_e's Keypad.bas program ? You will need the statement INCLUDE "keypad.bas" early in your code. You will need interrupts, and it will require you to use MPASM as the assembler unless you use Darrel's modified version.

I thought you were using Steve's for some reason.Originally Posted by Kalind
Where did you get the code and how is the keypad connected to the pic.

connected to the pic via port c.

I did a search on KEYPAD_ROW_PORT and the only places I could find that PARTICULAR define is connected with Steve's keypad routine...
hmmmm........

This looks like part of you code.

and here is the schematic for it

Make the necessary hardware changes and get the above code working. Do not add anything else yet, just the keypad code. (maybe a blinky to see if thing are running) but nothing else.
Then we will go from there.

All I can do to get Steve's routine to work, I will be posting something using it when I kill off a couple of bugs in my code, Finally with some help from Jeremy got my interrupts to work
