I'm just wondering how to get my name scrolled on both rows bi-directional.
The code I have here works fine, i'm just looking for the modifications to make the text scroll. Im using Mplab in assembly language.

  LIST  p = 16F887            ;Simply sets the processor type being used
  #INCLUDE <P16F887.INC>    ;file for processor, adds predifined labels

   __CONFIG _CONFIG1,  _HS_OSC & _WDT_OFF & _PWRTE_ON & _MCLRE_ON & _CP_OFF & _LVP_OFF
                            ; Sets many parameters
  org     0x00                ; Start the code at location zero


LCD_PORT Equ PORTB 

LCD_TRIS Equ TRISB
LCD_RS Equ 0x04 ;LCD handshake lines
LCD_E Equ 0x05

  
 CBLOCK 0x20 
 count ; Counter used when switch pressed has stopped 
 count1 ; 160us Counter variable 
 counta ; variables for delay timers 
 countb ; variables for delay timers 
 LCDTemp ; 4 bit for LCD

Notice the increment statement in this subroutine and in MESSAGE2?

 

Code is fixed
