Writes a data byte (one character) from the Hitachi HD44780
LCD controller.
xlcd.h
void WriteDataXLCD (static char data);
data
The value of data can be any 8-bit value, but should correspond
to the character RAM table of the HD44780 LCD controller.
This function writes a data byte to the Hitachi HD44780 LCD
controller. The user must first check to see if the LCD controller
is busy by calling the BusyXLCD() function.
The data read from the controller is for the character generator
RAM or the display data RAM depending on the previous
Set??RamAddr() function that was called.
This function operates identically to putcXLCD.

CURSOR_ON
CURSOR_OFF Cursor off

Cursor or Display shift defines
SHIFT_CUR_LEFT
SHIFT_CUR_RIGHT Cursor shifts to the right
SHIFT_DISP_LEFT
SHIFT_DISP_RIGHT Display shifts to the right
The above defines can not be mixed. The only commands that
can be issued are function set, display control and cursor/
display shift control.
This function writes the command byte to the Hitachi HD44780
LCD controller. The user must first check to see if the LCD
controller is busy by calling the BusyXLCD() function.
