upsd3300_lcd.c

Version:
November 30, 2004 - 2.0 - Initial Release.


Dependencies:
English font loaded into flash mapped into XDATA space at: ENGLISH_FONT_PAGE,
FONT_BASE_ADDRESS
Chinese font loaded into flash mapped into XDATA space at: 
CHINESE_FONT_PAGE, FONT_BASE_ADDRESS
Note: The Chinese font only needs to be loaded into flash if the option
ENGLISH_CHINESE_FONT is specified.

Description:
The uPSD3300 Enhanced LCD (ELCD) device driver is intended to provide functions 
to initialize the ELCD (GXM12232-1SL) and to display English ASCII characters
only or also Chinese characters.  The default compile option is for English 
only, but defining "ENGLISH_CHINESE_FONT" results in code compiled to support 
English characters and Chinese characters.

The font bit maps for English ASCII characters (0 to 127) are stored in flash
memory and is accessed via a standard lookup.  The font bit maps for user
defined Chinese characters are accessed via a special lookup operation.

Note: The lcd_init() function checks the first couple of bytes in the appropriate
location in flash memory to determine if the English font (and Chinese font, if
ENGLISH_CHINESE_FONT is defined) is loaded.  If it is not, the message "no font" 
is displayed on the LCD and the program execution loops forever in the lcd_init()
function.  In this case, the English font file (and the Chinese font file, if 
ENGLISH_CHINESE_FONT is defined) should be specified for placement in the 
appropriate flash sector in the PSDsoft project under "Merge MCU / DSP Firmware 
with PSD".  For messages to be displayed on the LCD, the appropriate font files
must be programmed into the flash for use by the printfLCD() function.
