Little problem right here with a if else loop

100ms isn't a big enough delay.... I usually use around 400ms... Time to let go of the button..

I got it going kind of nice.

Cool.... Sorry I haven't been much help... Your keypad function isn't that far from mine when all said and done...

I started it looking at one from boost C and and one from 8051 they was about the same tho just port names they where for 3x4 keypad.
The thing I don't get is C is not basic all them {} ; get me lost LOL. Then Mplab X I can be doing good and bang a big error.

I figured that out tho what happens is you make a change compile and it not using the code that you changed there is some kind of bug If you use the history

And roll back code you'll find the problem
