Hi,

on/off representes 1/0 right.

If it is 1/0 means no need to convert to decimal.

usually the problem is that the LCD can only accept characters so you need to covert the switch value into a character string to display it, e.g. assume your switch value is in the variable switch and the function LCDdisplay() displays a char[] array

char text[50];                          /* text displaying switch value */
sprintf(text, "switch = %d", switch);    /* convert switch value */                 
LCDdisplay( text);                       /* display text */
