Quan,

I have included the pin list that I have cut-and-pasted out of my Assignment Editor. 

Proto2_LCD  Location  PIN_U10
Proto2_LCD  Location  PIN_V10
Proto2_LCD  Location  PIN_W10
Proto2_LCD  Location  PIN_Y10
Proto2_LCD  Location  PIN_V11
Proto2_LCD  Location  PIN_U11
Proto2_LCD  Location  PIN_W11
Proto2_LCD  Location  PIN_Y11
Proto2_LCD_E  Location  PIN_T10
Proto2_LCD_RS  Location  PIN_Y9
Proto2_LCD_RW  Location  PIN_W9

As you can see, I used the same pin names as the reference design, but prefixed each name with Proto2_

You mentioned moving the LCD from PROTO1 J10 to PROTO2 J15, on my board the lcd is attached to the PROTO1 J12. Also I forgot to mention i am using the Cyclone dev kit from Altera.[/b]

I too am using the Altera Cyclone dev kit, and I meant proto1, J12. Sorry for the confusion.
