[bassbig]

HI

I am new to electronics but have managed to get the hardware working

What I have not been able to achieve is to write a programme to scroll a long message .

Has anyone got a programme they can let me copy and then change the message

hopefull

John

Welcome to the PICAXE Forum.

The easiest way to scroll a message is to simply rewrite it on screen starting one character further on each time. One example -

Do
  SerOut LCD, N2400, (254,$80)
  For b1 = 0 To 15
    b2 = b0 + b1 // 22 ; 22 is the length of message below
    ;            123456789-123456789-12
    LookUp b2, ("This is a long line - "),b3
    SerOut LCD, N2400, (b3)
  Next
  Pause 500
  b0 = b0 + 1
Loop

You need to add a SYMBOL definition for the LCD pin which indicates which PICAXE pin drives the AXE133Y. For example if your AXE133Y is connected to pin B.7 -

Symbol LCD = B.7

And the full code, including a pause to ensure the AXE133Y has initialised, would become -

Symbol LCD = B.7

Pause 2000

Do
  SerOut LCD, N2400, (254,$80)
  For b1 = 0 To 15
    b2 = b0 + b1 // 22 ; 22 is the length of message below
    ;            123456789-123456789-12
    LookUp b2, ("This is a long line - "),b3
    SerOut LCD, N2400, (b3)
  Next
  Pause 500
  b0 = b0 + 1
Loop
