lcd options

[richardb]

I Have a 4x20 lcd display and if i WriteAt(3,1,"here") the text appears at about coulumn 16(this is a guess)
should there be an option to set the screen size?
i have to print on line1 at column 21 to work.

Can you try the following:

(1) In the code explorer window, you will see 'LCD' in the includes section. Click on 'LCD' to open the file in the IDE

(2) At the top of the LCD code, you will see a small 'lock' icon with the text

"LCD is a compiler system file and is read only"

Double click on the lock icon so you can edit the file.

(3) Scroll down to the following sub

Code: Select all

public sub MoveCursor(pLine, pCol as byte)

and make the following changes

Code: Select all

public sub MoveCursor(pLine, pCol as byte)
   dec(pCol)
   select pLine
      case 1 : SetDDRAM(pCol)
      case 2 : SetDDRAM($40 + pCol)
      case 3 : SetDDRAM($14 + pCol)   // ** change to $14
      case 4 : SetDDRAM($54 + pCol)   // ** change to $54
   end select
end sub

Save your changes, then close the 'LCD.bas' module. Please let me know if it works for you...

That works perfectly.
