How to Pull ups port c

[karthickiw]

Dear CCS Friends,


In my project I used 5 x6 matrix keypad. For that I take some sample code from CCS forum. In this program, the program has pull_ups on the row pins like port_b_pullups(TRUE);. In my project I connect the 3 rows connected in portB, one row in portD.2 and other row one in portC.2. I'm also using Pullups for the three ports like below:

Read the data sheet.
Does the PIC you are using offer pullups on PortC?.
Most don't (can't think of any that do...).
Hence the error.

Best Wishes

If the hardware is not there, NO amount of software will make it work. If the PIC does not have internal pullups inside there is no way to enable them. Read the spec. sheet and see what hardware is inside.
