Syntax
Parameters
The LK204-7T-1U allows for upta to eight custom defined characters to
be added onto the the character set. A custom character is a five by eight
pixel matrix with each row represented by a byte value. For example:
Each bit value of one, in the table, represents an on pixel, whereas a value
of zero represents a pixel that is turned off. Therefore in order to define
custom character ’h’ you would send the command byte prefix 254 fol-
lowed by the command 78. Next, you will have to select the memory
location in which you wish to save the character in. The available mem-
ory locations for this command are zero through to seven. After sending
the memory location, or [refID], you may then send the eight byte custom
character data in sequence from the top to the bottom.
Once you have defined a custom character you may display it by sending
the display module the [refID]. For example if a custom character was
saved in position one, the command to display the custom character, at
the current cursor position, would be simply to send the number one to
the display module without quotes.
