I haven't digested your code but the first address on Line-1 is 0x00 and on Line-2 is 0x40 |

I am having a problem trying to find a method to get the charactures to be displayed on a new line. I am using a pic16f887. I want the number stored in count2 to be written along the lower line of the LCD.
Here is the code that i am using to develop the display
#include <p16F887.inc>
__CONFIG _CONFIG1, _LVP_OFF & _FCMEN_OFF & _IESO_OFF & _BOR_OFF & _CPD_OFF & _CP_OFF & _MCLRE_OFF & _PWRTE_ON & _WDT_OFF & _INTRC_OSC_NOCLKOUT
__CONFIG _CONFIG2, _WRT_OFF & _BOR21V
