5.1.7 Initialize Medium Digits (254 109)
This command defines the 8 special characters to be blocks suitable for use in drawing medium digits.
Any previous definitions will be lost.
Once this command has been issued, any number of medium characters may be placed until the charac-
ters are redefined by another command.
5.1.8 Draw Medium Digits (254 111 [row][column][digit])
Draws a medium digit in [row] and [column] using the specified [digit]. Medium digits occupy two
rows. When the [row] is specified to be “1”, the medium digit will be displayed correctly. When the [row]
is specified to be “2”, only the top part of the medium digit will be displayed. When [row] is specified to be
“0”, only the bottom part of the medium digit will be displayed.
6 Miscellaneous Commands
The commands listed in this chapter don’t readily fit in any of the other categories, or are used in more
than one category.
6.1 Command List
Some commands, marked with an “R”, may be "Remembered" to set new defaults that will be in effect
each time the unit is powered on. When “remeber” is set / turned on, these commands are automatically
remembered to take effect each time the unit is powered on, therefore there is no need to send the save
function.
6.1.1 Remember (254 147 [0|1])
This command allows a number of settings, such as cursor state, backlight, etc., to automatically be
stored to non-volatile memory so they become new defaults. The command should only be used when
required for two reasons;
1. Writing to non-volatile memory ( using the “save” function) is time consuming and slows down the
operation of the display.
2. Non-volatile memory has a ’write limit’ and may only be changed approximately 100,000 times.
6.1.2 Clear display (254 88)
This command clears the display and resets the text insertion point to the top left of the screen.
