  • LCD Test Screen

    Hi,

    I have a question. How do you change the LCD Test Screen?

    When you ground SC and SD on the LCD and then power it up. It displays a test screen Example:
    ------------------------
    V1.2 melbas.com
    N9600 I2C=$50
    Brightness=0
    Chars=20 Lines=4
    ------------------------

    How do you change this to display what you want it to say?

    The test screen is intended to verify operations of the LCD.
    It's not meant to be a customizable "Splash" screen.
    It only displays when you short the SD and SC pins to ground.

    If you want a "Splash" screen ... you must have first saved the Splash screen at location 0 using the Write String (ESC w n s) command.

    When you turn the LCD on, it will display the splash screen automatically.
    And you can display it any time using the Display String (ESC S n) command.
