Scrolling LCD display

Archiver

Hi guys,

I want to scroll a lcd display vertically, is that possible?

My intention is:

---

1) vacuumtest |
2) pressuretest|
3) liquidtest | LCD SCREEN
4) ««««««--|

---

5) automatically



when I push on a arrow down pushbutton, the screen must be:

---

1) ªªªªªª--|
2) pressuretest|
3) liquidtest | LCD SCREEN
4) automatically

---

I wonder what's the shortest possible way to create this (i'm using
an 4x20 LCD display)?




Regards,

Tim

You could write a loop that reads a line and copies it to the next (above or below, depending on scroll direction). I don't think you're going to find a magic answer, short of using a specialty LCD controller that may have vertical scrolling built in.
