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.
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.
6.1 Command List
This chapter deals with command functions.
6.1.1 Remember
This command allows a number of settings, such as cursor state, brightness, 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 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.
Commands which may be used with the ’remember’ function are marked with an "R" in the "Default" column
in the command tables. The example shows the procedure to set “Auto scroll ON” as the default condition.
Commands are shown in both decimal and hex in this example;
