HI,
I am doing a project to get input data from a 4X3 matrix key pad (just as in mobile) and display it in lcd using pic 16f877A.... the keys are like (.,1),(abc2),(def3),............(wxyz9).... i dont know how to write code for key identification as it uses multiple character in a single key..... if any one knows please help....:-(
