Hello All,
I have a project where I am using a normal 4x4 keypad. My issue here is that I need it to be able to enter numbers + alphabet characters similar to the mobile phone in SMS editing mode when you press a certain key number it scrolls through a number of character before selecting the last one as final result.
Does anyone have some sample code for this application? I already have a working numeric keypad (with one character only per key). I tried to make multi-dimensional array for the decoding function, but there is something I am missing int he timing I guess.
If anyone can suggest some code (preferably C) that would be great.
Thanks,
Gam
