20x4 LCD with Adafruit USB/Serial LCD Backpack Splash Screen

Post by D2Tech »

I have an Adafruit USB/Serial LCD backpack that I would ideally like to remove the splash screen on.

The documentation states
Change startup splash screen - 0xFE 0x40 - after sending this command, write
up to 32 characters (for 16x2) or up to 80 characters (for 20x4) that will appear
as the splash screen during startup. If you don't want a splash screen, write a
bunch of spacesMoving and changing the cursor:

I have done a
LCD.write(0xFE)
LCD.write(0x40)
LCD.print(" ")

But this does not seem to change the splash screen. I have tried a few other things too.

Would anybody happen to know the correct syntax to remove the splash screen..

Many Thanks in Advance

Print two full lines of spaces, with newlines. See if that works.
