‘R’ – 52h – Preset LCD Rotation String (v4.10 and greater)
This command is used to preload a null-terminated string into the LCD rotation
buffer. You
must
include the null character at the end to return to normal
command mode. The string will not be visible on the display until the Velocity
command is issued (see ‘V’ 0x56).
This command is primarily used to present text to a user that is too long to
display on the smaller 1 x 16 LCD. The buffer accepts up to 32 characters.
Example: Pre-load the string “Mary had a little lamb. “

‘V’ – 56h – Rotating String Velocity (v4.10 and greater)
Once a string has been preloaded using the ‘R’ command, the string can be
shown, rotated at various speeds and stopped using the velocity command. A
velocity of 0 stops the rotation. Velocities of 1 through 7 set the rotation speed in
characters per second. Only the three least significant bits of the velocity are
(currently) implemented.

In Line Edit mode, the ‘V’ command can be used in conjunction with the ‘K’
command (Next User Key Press Clears LCD). This allows for longer prompts for
the user such as “Press ENTER to continue… “.
Example 1: Show and rotate the pre-loaded string at 2 characters per second.
