3.4.12 Cursor right (254 77)
Moves the cursor one position to the right but does not erase any character that may be in that position.
This command moves the text insertion point even if the cursor is turned off.
4 Bar Graphs and Special Characters
The display includes the ability to draw bar graphs, either horizontally or vertically, large numbers, and
allows users to define up to eight special characters. Eight characters (ASCII values 0x00 to 0x07) are set
aside for use with bar graphs, user defined characters, and large digits. Since the same 8 characters are used
for each function, the functions may not be used simultaneously. The characters may be defined or redefined
at any time by issuing the commands shown in this section. Once defined, they may be used either by means
of the bar graph commands, or by simply issuing one of the ASCII values 0x00 to 0x07 which is not prefixed
by the command byte, 254.
4.1 Command List
4.1.1 Initialize wide vertical bar graph (254 118)
This command defines the 8 special / user characters to be blocks suitable for use in drawing wide
vertical bar graphs, such as 5 pixels. Any previously existing definitions will be lost. Once this command
has been issued, any number of vertical bar graphs may be drawn unless the characters are redefined by
another command.
4.1.2 Initialize narrow vertical bar graph (254 115)
This command defines the 8 special / user characters to be blocks suitable for use in drawing narrow
vertical bar graphs, such as 2 pixels. Any previously existing definitions will be lost. Once this command
has been issued, any number of vertical bar graphs may be drawn unless the characters are re-defined by
another command.
4.1.3 Draw vertical bar graph (254 61 [column] [height])
Draws a vertical bar graph in [column] having a height of [height] pixels. The height may range from
0 to 20 (0x00 to 0x14) pixels. The necessary characters must first be initialized by either of the commands
shown in section 5.1.1 or 5.1.2, which will determine the width of the graph drawn. Graph may be erased
by drawing a bar graph of height = 0 in the same column.
