  • Mirroring UDG'sJust wondered is there a quick an easy way of mirroring UDGs (byte values)? i.e. BIN 11110000 becoming 00001111 etc.

    Using a 16 bytes lookup table is a good compromise as well, flip each half byte.

    This is one of those things, like lookup tables, that I'm going to be too dense to understand, even with two explanations, isn't it?
