character 0's CGRAM data locations. Then it will place the cursor back on
the display (DDRAM) and print the character on the screen.
LCDOUT 0, 64+0, [00, 10, 00, 04, 17, 14, 00, 00]
LCDOUT 0, 128+0, ["Custom Char: ", 0]
The number 64 in the Command argument is the LCD's "Move to CGRAM
Address" instruction and the 0 that is added to it is the location of the first
row of data for the character 0. The LCDOUT command will write the
first OutputData value (00) to this location, the second OutputData value
(10) to location 1, etc. If we wanted this custom character to affect
character 1, instead of 0, we'd have to adjust the value of the "Move To..."
command, i.e.: 64+8. To affect character 2, we'd use 64+16.
To try the example above, don't forget to execute the LCD initialization
code (shown in the LCDCMD description) first and never forget to move
the cursor back to the screen (as with the last command, above) when
you're done writing the character data to CGRAM.

NOTE: This example program can be
used with the BS2p, BS2pe, and
BS2px. This program uses conditional
compilation techniques; see Chapter 3
