Interesting. I think the easiest way would to have each row on its own shift registers. It'd be trivial but if each pixel was on LED you could only slant at 45°

Interesting. I think the easiest way would to have each row on its own shift registers. It'd be trivial but if each pixel was on LED you could only slant at 45° intervals, which would be annoying. Maybe make each pixel 2LED×1LED (vertical). This would be the equivalent of shifting it by adding an offset to the characterset bitmap that depends on the position vertically in glyph.
