COM lines of the display.
RAM requirements
This display driver may be used with or without a display data cache, containing a
complete copy of the LCD data RAM. If a cache is not used, there are no additional
RAM requirements.
It is recommended to use this driver with a data cache for faster LCD-access. The
amount of memory used by the cache may be calculated as follows:
Size of RAM (in bytes) = BitsPerPixel * (LCD_XSIZE + 7) / 8 * LCD_YSIZE
Additional run-time configuration
The table below shows the available run-time configuration routines of this driver:
Routine Description
GUIDRV_SLin_Config Passes a pointer to a CONFIG_SLIN structure to the driver.
GUIDRV_SLin_SetBus8
Tells the driver to use the 8 bit indirect interface and passes pointer
to a GUI_PORT_API structure to the driver.
GUIDRV_SLin_SetS1D13700 Tells the driver to use an Epson S1D13700 controller.
GUIDRV_SLin_SetSSD1848 Tells the driver to use a Solomon SSD1848 controller.
GUIDRV_SLin_SetT6963 Tells the driver to use a Toshiba T6963 controller.
GUIDRV_SLin_SetUC1617 Tells the driver to use an Ultrachip UC1617 controller.
GUIDRV_SLin_Config()
Description
Passes a pointer to a CONFIG_SLIN structure to the driver.
