Thanks Edward, the LCD must operate whether the serial DAC is operating or not. My LCD and my serial operated DAC must be totally autonomous.

I saw a post recently where a guy was running three serial ports out of one chip, so I am sure there is some way to run the LCD and still have one serial output.

Steve, correct me if I'm wrong. The shift out command looks to be a one bite at a time affair with a lot of code.

I could get a parallel operated DAC, but wouldn't I still need a clocking pin?

Your suggestions are greatly appreciated.
