In reply to Farah Mansor. If you are using Keypad, you won't be able to connect diodes like that.

In reply to A. Lahiru. About program is not using any MikroC specific functions. So you can easily convert it to MPLAb.

In reply to Ligo George. Right, how can this be modified to just output an index of 1-16 rather than actual characters? Was looking for something more generic. Is it possible to know the main settings for the ports like TRIS etc?

In reply to Syed.

You can make it .. using above two functions…
Just call the function to read keypad.. and print in on the LCD.
