# ex16_qwiic_serlcd_set_splash.py
#
# This example demonstrates how to create your own custom splash screen.
#
# This is done by first writing the text you want as your splash to the display,
# then 'saving' it as a splash screen.
#
# You can also disable or enable the displaying of the splash screen.
#
# Note - The disableSplash() and enableSplash() commands  
# are only supported on SerLCD v1.2 and above. But you can still use the
# toggle splash command (Ctrl+i) to enable/disable the splash.
