Hi I'm a year 1 student in Fiji and working on a project using a 4x4 keypad. My problem is that the ccs pic c compiler only has a driver for a 4x3 keypad and not a 4x4. Please help. |

Hi,
Hmmm, how hard did you look???
There are numerous examples of 4x4 keypad drivers available on the forum. Here is one by PCM programmer: http://www.ccsinfo.com/forum/viewtopic.php?t=28022&start=14

You need to look at and understand how CCS coded the 4 by 3 driver, then decide how to add one column or row.
If we just give you the code, then you've not learned anything.
