Im trying/struggling to interface a maplin LCD (N25AZ) with a Pic (this will be my first time using a LCD)

Datasheet for LCD( http://www.maplin.co.uk/Media/PDFs/N25AZ.pdf\)

ive run into 2 areas of confusion.

- the datasheet lists 3 power pins; VSS,VDD and V0?
what do i connect V0 to?

- the datasheet says i can run it in 8 bit mode.
all of connection seem fairly straight forward expect for this one #define LCD_DATA_PORT, what pin on the lcd should i connect this output to?

Thanks

  V0 would be the LCD contrast adjust. The data sheet should show you how to hookup, or do a search if not.
  
  8 bit modes is 8 lines, one from each Port pin like RB0, RB1, RB2...RB7. Set the LCD_DATA_PORT like in the Online Help/LCD examples.
