Is the source code zip file still available for the Stamp Works txt?? I need SW21-EX11-LCD_Demo.BSP and so far I haven't found that code in the Stamp Works book. Thanks.

I think this is it:

Thanks, I think the issue might be the values in the

section... I tried looking at the datasheet but getting REALLY confused as to the values i need to change. http://topwaydisplay.com/Pub/Manual/LMB162ABC-Manual-Rev0.2.pdf here is the datasheet for my lcd. If I am reading it right, n i doubt I am, LcdCls needs to be $20 n LcdHome $00, but providing thats right, I am blank on the rest other then LcdLine1 being $00 n LcdLine2 being $40?? I am not sure how to decode the address information...

Sorry -- my fault. As you've determined by now, the correct value is $C0.

In other programs I added the values you see above to LcdDDRam which would give you $80 for LcdLine1, and $C0 for LcdLine2.

Actually I am not sure I figured any of the values out other then maybe lines 1 & 2. $C0 i didnt even come across that value at all when i tried to guess at what i was doing.

I mostly use the Propeller now, and here are the constants from my LCD object that will work with 1-, 2-, or 4-line LCDs.

con
  
  CLS     = $01                                                 ' clear the LCD 
  CRSR_HM = $02                                                 ' move cursor home
  CRSR_LF = $10                                                 ' move cursor left 
  CRSR_RT = $14                                                 ' move cursor right 
                                                                  
  CGRAM   = $40                                                 ' character ram
  DDRAM   = $80                                                 ' display ram
                                                                 
  LINE0   = DDRAM | $00                                         ' cursor positions for col 0
  LINE1   = DDRAM | $40                                          
  LINE2   = DDRAM | $14                                          
  LINE3   = DDRAM | $54                                          
                                                                 
  #0, CRSR_NONE, CRSR_ULINE, CRSR_BLINK, CRSR_UBLNK             ' cursor types

You'll also note that I refer to lines 0 to 3, instead of 1 to 4. This makes the numbering consistent with column numbering (which is also zero-indexed).

Ok I will try those values n see what happens. Thanks.
