Serout & lcd

[KenM]

When I download the following program the desired text is displayed on the LCD.

If I remove power, then re-apply power should the same occur?

Removing power and reapplying power the text is not displayed, cursor is at line 0 position 0.

If I hit reset, the desired text is displayed.

Pause 2000 yeilds the same result.

This is using a Parallax serial LCD.

What am I missing?

You need to give the LCD at least five milliseconds after a clearscreen command.· I've attached an updated (for BS2p) demo program that provides a lot of helpful constants.

Jon,
Thank you....dang-it!!!!!!!!!!!!!!!!!!!!!!
Right there in the documentation..."You will need to pause 5mS in your code after sending the Form Feed command..."
Sorry for wasting your time.
The demo program is cool.
