Our driver doesn't support this. But, it's a good thought. =20
=20
The problem is that our device shares the i2c bus with other devices
that aren't as well-behaved. So, we get occasional corruption. I've
worked out a scheme that should repaint sufficiently. But, I wish our
board designers had put our device on its own bus.

Thanks everyone for a fine project.

We have some deep hardware issues that might not get resolved. But,
it's pretty simply to add code in our client to request a repaint.

If you're using the HD44780 driver, there is a RefreshDisplay option in
LCDd.conf
