[Lcd4linux-devel] progress report RE: HD44780 stuff

[Bill P. <goa...@ya...>]

Hi.

I have a question on how things that slightly deviate from standard should be done.
For example the CU series VFDs from Noritake/Itron. They are HD44780 compatible but
contrast doesn't exist - Pin 3 goes nowhere. It's a brightness setting in software.

The relevant bits are R/W low, RS high, and put 0x00h-0x03h on the pins for 4 levels of
brightness. Add a cfg_number "VFDBrightness" (or whatever) entry, the sprintf and the
HD_write call and that's it. 

It seems redundant duplicating the HD44780 driver for a slight variant.

Thoughts?
