i am interfacing LCD and a 4x4 keypad with PIC18f6520. i wrote the code in embedded C. when ever user press a key, it is displayed on LCD. i made the checks for keypad like this (for printing 1)
can some one please help me how i can use backspace function in this case for removing characters on LCD one by one, (just like mobile and keyboard) and also guide me about any library if required for that method.
pressed key 012345
pressed backspace key - 01234, again-0123 so on.
Thank in Advanced.
