Using
u8g.setContrast(208);
works as it should and sets the contrast. But I have a few questions. From what I’ve read in the datasheet the contrast value is a 6 bit value. I’m guessing the range 0 – 255 is divided down to 0 – 63?
I’ve begun investigating bdf fonts using FontForge. I looks like converting a font then modifying / drawing the bitmap for the size I want might be the best method, but I don’t really understand how point size converts to pixel size. I think I have a lot to learn before I can produce a usable font.
Thanks again for all of your help and support.
