Post subject:  S1D13700 gray scale

Hello,

I`m working with the S1D13700 controller and I have some troubles with the gray scale mode (2bpp). Which parameter do I have to change (for an 320x240 display)?

At the moment the screen is vertically divided in two equal screens (for graphics). And my font (on the graphic layer2) is half as big as usual.

If I use the black & white screen everything is working.

Have anyone of you an idea of this problem?

best regards
GJM

ok, now I find the error - I forgot to increase the horizontal image length...

But there`s another problem with the gray scale: How is the exact definition if a pixel is black, dark gray or white? If all 8 pixel are 0xFF then I get black....
