Thread: [Lcd4linux-devel] support for KS 0108 controller

Hi,

The question is simple. Is there current support for displays with a 
KS0108 controller?

regards,

Paul

Not to my knowledge.

Isn't the KS0108 somehow compatible to the HD44780? Or am I mixing
things up here?

I am afraid it is not. It is graphics only and no 4 bit mode. But it
doesn't look to complicated. Most complicated is my connection scheme. I
wan't to connect it to my i2c bus. (Stupid me!) I have two options for
this, one is using a slightly exotic 16 bit IO expander. Or using 2
'standard' PCF8574 devices, one for 8 data lines and one for the control
lines. Personally I favor the second option, since ironing is less
complicated.

Any comments?

Paul

I would go for a two PCF8574 devices.
Easier to maintain, I would guess...
And also more simple integration with current code.

Hi there,

Great! Another graphical display!

Times are coming when we're in the need for more cool & sexy graphical
widgets :-)

I have absolutely no idea what you're talking about, so I vote for the
second one.

Is it possible to connect it to the parallel port, too?
