/*------------------------------------------------------------------------------ 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. Copyright (c) 2004 STMicroelectronics Inc.
