For those who want to cram more characters per line, please send me the data for your preferred 4-bit font and we'll try to include this into the firmware. It should be as complete a font as possible, with mixed case and symbols. You can bit-pack the characters into pairs if you want. The ARM can surely mask out the proper nibble.

Delicon is embedded the data in the firmware using C array syntax. Like so:

unsigned byte ansicharacters[256][8] = {

{ 0x00, 0x7C, 0x82, 0xAA, 0x82, 0xBA, 0x92, 0x7C }
...
}

Thanks.
