Re: KS0066 / S6A0069 support in lcdproc

Hello,

"S6A0069" is the new name of the KS0066 which is what we call
'HD44780-compatible'. You do not need to do any programming to get it
work with LCDd. I have at least one display using the S6A0069X01 and it
works.

The initialization in your code example may be different but that should
not make a difference.

Perhaps the wiring of the control lines your display uses is
incompatible with LCDd. Please check
http://lcdproc.sourceforge.net/docs/current-user.html#hd44780-8bit-winamp or
http://lcdproc.sourceforge.net/docs/current-user.html#hd44780-8bit-lcdtime
any verify that your display's RS and EN lines are at the correct
parallel port pins. The RW if not connected to GND should match as well.

It may also be a timing problem (your example uses other timings). In
this case you can experiment with the 'DelayMult' and 'DelayBus'
settings in LCDd.conf.

Regards,
Markus

I would like to learn C, and probably will start learning in my free time, but it would take a lot of time to reach the skill level necessary to make this implementation. Is any of you willing to help implement this one?
