PICBasic Pro interfacing with graphic LCDs

[Demon]

Hi,

MicroChip has released a new family of PICs which support 128x64 pixel graphic LCDs; the 18Fxx90 series.

Has anyone tried working with these yet? There isn't much available yet except the garble stuff I read in the PIC datasheets (well, it's garble to me).

I was hoping someone had some code snippet I could study.

Thanks, and have a nice day!

Here's an example of not understanding the datasheet:

There was a link in another thread to a site containing ideas for interfacing with a 51320 graphic LCD. In a demo program, they had this initialization value:

BIAS con $A2 '%10100010 $A2 = 1/9 bias

I did a search in the 51320 datasheet for BIAS, and the only values I saw were 1/7. This is where I get really confused, where did this person pull 1/9? And how can we go about chosing alternate BIASes? Is there a list I missed? Or is there a formula that went over my head?

Any help would be greatly appreciated at this point. I can follow the person's circuit, I can follow his initialization routine against the datasheet, but I have absolutely NO idea where he gets his values.

Thanks, and have a nice day!
