Jonathan Austin 1:8aa5cdb4ab67 27 * Class definition for a MicrobitFont
Jonathan Austin 1:8aa5cdb4ab67 28 * This class represents a font that can be used by the display to render text.
Jonathan Austin 1:8aa5cdb4ab67 29 *
Jonathan Austin 1:8aa5cdb4ab67 30 * A MicroBitFont is 5x5.
Jonathan Austin 1:8aa5cdb4ab67 31 * Each Row is represented by a byte in the array.
Jonathan Austin 1:8aa5cdb4ab67 32 *
Jonathan Austin 1:8aa5cdb4ab67 33 * Row Format:
Jonathan Austin 1:8aa5cdb4ab67 34 * ================================================================
Jonathan Austin 1:8aa5cdb4ab67 35 * | Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 |
Jonathan Austin 1:8aa5cdb4ab67 36 * ================================================================
Jonathan Austin 1:8aa5cdb4ab67 37 * | N/A | N/A | N/A | Col 1 | Col 2 | Col 3 | Col 4 | Col 5 |
Jonathan Austin 1:8aa5cdb4ab67 38 * | 0x80 | 0x40 | 0x20 | 0x10 | 0x08 | 0x04 | 0x02 | 0x01 |
Jonathan Austin 1:8aa5cdb4ab67 39 *
Jonathan Austin 1:8aa5cdb4ab67 40 * Example: { 0x08, 0x08, 0x08, 0x0, 0x08 }
Jonathan Austin 1:8aa5cdb4ab67 41 *
Jonathan Austin 1:8aa5cdb4ab67 42 * The above will produce an exclaimation mark on the second column in form the left.
Jonathan Austin 1:8aa5cdb4ab67 43 *
Jonathan Austin 1:8aa5cdb4ab67 44 * We could compress further, but the complexity of decode would likely outweigh the gains.
