5.1.8 Place large digit 254 35 [col] [digit]
This command allows the large digits to be drawn on the LCD screen. Numbers of almost full display
height may be placed along side regular text on four row displays. The column number has a maximum
value which is less than the display width because the digits are all three columns wide.
Before using this command the “Initialize large digits” command must be issued to define the blocks
necessary to make up the digits. If regular text and large digits are mixed on one screen, the user should
always set the display cursor position before placing regular text because the creation of a large digit will
leave the cursor position to the bottom right of the large digit and not at the last regular text write position.
[col] can have values from 0x01 to 0x12 (1 to 18).
[digit] has values from 0x00 to 0x09 (0 to 9).
