MobileWill:
Thanks. Then the length would be 8 right?

So are the ones after the tilde the extended ascii characters or you just used whatever it generated?

I might try this font table

Gammon Forum : Electronics : Microprocessors : Interfacing LED displays with the MAX7219 driver

Of course I can't use the whole table since it won't fit in memory, well it might on the 32u4, which I will be switching too once I get one.

The bottom of the array:

        0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
        0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
        0x1C, 0x2A, 0x49, 0x49, 0x41, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x51, 0x49, 0x41, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x79, 0x41, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x49, 0x51, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x49, 0x49, 0x2A, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x49, 0x45, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x4F, 0x41, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x45, 0x49, 0x41, 0x22, 0x1C, 0x00};

becomes:

	0x00, 0x00, 0x00, 0x06, 0x49, 0x30, 0x00, 0x00,
        0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
        0x1C, 0x2A, 0x49, 0x49, 0x41, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x51, 0x49, 0x41, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x79, 0x41, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x49, 0x51, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x49, 0x49, 0x2A, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x49, 0x45, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x41, 0x4F, 0x41, 0x22, 0x1C, 0x00,
        0x1C, 0x22, 0x45, 0x49, 0x41, 0x22, 0x1C, 0x00};

The reason there are extras is because the guy who created the font made some hourglass charaters which I guess he needed for his project.
