About the vertical fonts, it will be hard for the character displays. There are only 8 custom character memory for the display so there won't be enough to make out the vertical display plus the 4*8 matrix can't be broken. I'll have to use a graphic display (next step!).
maybe just for digits ?
Any applications for this potential display? I suppose with the character display capability and 20X4 display, I can push it up to 4X10.
