hi,
i am interfacing LCD and a 4x4 keypad with atmega16L. i wrote the code in C. when ever user press a key, it is displayed on LCD. i made the checks for keypad like this (for printing 1)
if(bit_is_clear(PIND,c1))
LCD_write('1');
can some one please help me how i can use backspace function in this case, and also guide me about any library if required for that method.
thanx
