Create Screen (61-0A)
This command allows the firmware to create a new screen instance based on a screen theme and
send out a Screen ID accordingly.
After the screen is created, user can send a
Show Screen (61-05)
command or
Add/Update Object to
Screen (61-07/08)
command using the created screen’s name.
Screen themes should be pre-defined in firmware. The VP6800 and host should already have the
screen theme IDs.
