Hi dear all.
I'm writing software to drive a F-51851 lcd display which uses 2 NJU6676 to drive a 240*64 dots screen. It so happens I have no hardware prototype to support testing yet.
My major issue is understanding when to care updating the CS1/CS2 bits flags.
Should PowerON/Poweroff sequences be duplicated for each controller ?
Regarding row and col adressing :
I seems like row/col adressing should follow a scheme where the whole display is splitted in four quadrants. So Depending on the value col (row) should be adressed on the proper controller accordingly. So im some cases a row/col should be defined through the same controller, in other cases a controller switch should be achieved prior to the second setting. Can anyone can confirm this ?
Regarding display data read and write :
How to define the right controller to fetch/display a data ? Does it depend on the concerned col only ?
Here's a list of the docs I have :
F-51851 LCD Module Technical Spec and 20090225 OAI-80018AA-7601-B STEP-Series Application Note.pdf, both from Optrex.
NJU6676 from JRC.
Thanks for your attention.
P.S. I'm aware this display is reaching end of life cycle, so I plan to upgrade project. But up to now replacement is only black/white, not green as expected. Futhermore I have 2 parts I costly acquired so I wish to use them in prototypes. Replacement part F-55471 seems to have minor cabling and functionnal differences. So functionnal understanding should be preserved.
