1:8aa5cdb4ab67 | 38 | * Class definition for a MicrobitFont |
Jonathan Austin |
1:8aa5cdb4ab67 | 39 | * This class represents a font that can be used by the display to render text. |
Jonathan Austin |
1:8aa5cdb4ab67 | 40 | * |
Jonathan Austin |
1:8aa5cdb4ab67 | 41 | * A MicroBitFont is 5x5. |
Jonathan Austin |
1:8aa5cdb4ab67 | 42 | * Each Row is represented by a byte in the array. |
Jonathan Austin |
1:8aa5cdb4ab67 | 43 | * |
Jonathan Austin |
1:8aa5cdb4ab67 | 44 | * Row Format: |
Jonathan Austin |
1:8aa5cdb4ab67 | 45 | * ================================================================ |
Jonathan Austin |
1:8aa5cdb4ab67 | 46 | * | Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 | |
Jonathan Austin |
1:8aa5cdb4ab67 | 47 | * ================================================================ |

Jonathan Austin |
1:8aa5cdb4ab67 | 50 | * |
Jonathan Austin |
1:8aa5cdb4ab67 | 51 | * Example: { 0x08, 0x08, 0x08, 0x0, 0x08 } |
Jonathan Austin |
1:8aa5cdb4ab67 | 52 | * |
Jonathan Austin |
1:8aa5cdb4ab67 | 53 | * The above will produce an exclaimation mark on the second column in form the left. |
Jonathan Austin |
1:8aa5cdb4ab67 | 54 | * |
Jonathan Austin |
1:8aa5cdb4ab67 | 55 | * We could compress further, but the complexity of decode would likely outweigh the gains. |
