My Nios development board is the cyclone version.
When I use the safe configuration, and the example routine: lcd_demo1.c,
it runs properly, the LCD displays the messages.
But when I use the "Nios_HW_Tutorial_Cyclone_1C20" to config my Cyclone, then the lcd_demo1.c under the "$\Nios_HW_Tutorial_Cyclone_1C20\cpu_sdk\src" does not work properly. The phenomenon is:The LCD seems to be frozen!! It does not responce to the routine.
However, when I use oscillograph to test the pins of the LCD, the data are still transfered to LCD.
What's wrong with my LCD or what problem with my operation?
