12864 graphic LCD question...


New member
Hi all,

I've finally gotten a chance to program my 128x64 LCD.

I'm having a little odd problem though.

I go thru turning on both left and right CAS, setting my X to page 0, Y to loc 0.

The left hand side of the screen (cas1) is completely filled in. The right hand side is blank.

I can draw my bitmaps out to the left hand side, and they appear normal, but I'd really like to start with a blank page rather then a filled one - has anyone else run into this issue, and if you have, how did you solve it???
