// ============================================================================= // font5x7.h - 5x7 dot-matrix bitmap font table // ============================================================================= // // WHAT THIS IS // A 256-glyph bitmap font (derived from the classic Adafruit GLCD 5x7 font, // "glcdfont.c") used to render single characters on 5-column x 7-row LED // matrix / dot-matrix displays. Several glyphs have been hand-modified from // the original Adafruit set (see "old:" comments below for the replaced // values), and the upper half of the table (0x80-0xFF) has been customized // with Hungarian/German accented letters (a, ä, ö, u, Ä, Ö, U), Greek // letters, and math/misc symbols in place of the original CP437 glyphs. // // DATA LAYOUT // _font[] is a flat byte array with exactly 5 bytes per character: // _font[c*5 + col] for col = 0..4 (NUMCOLS in wordclock.ino) // Each byte is one COLUMN of the glyph (column-major, not row-major). // Within a byte, bit 0 (LSB) is the TOP pixel of that column and bit 6 is // the BOTTOM pixel (7 rows tall); bit 7 is unused/always 0. Columns are // ordered left-to-right within each 5-byte block. // The table holds 256 entries indexed 0x00-0xFF, i.e. it is indexed // directly by (unsigned) character code - there is no separate character // map or lookup table. // // WHO USES IT // wordclock.ino is the only consumer: it does #include "font5x7.h" and // reads the array in show(byte c) as // loccol[i] = _font[c*NUMCOLS + i]; // then calls transposePattern() to convert the column-major glyph into the // row-major bit pattern actually clocked out to the display hardware // (honoring the _upsidedown orientation flag). No other .ino in this // project references _font[] or includes this header. // // CHARACTER RANGE // 0x00-0x1F : custom symbols (smileys, suits, arrows, euro sign, etc.), // not standard control characters. // 0x20-0x7E : standard printable ASCII (space through ~). // 0x7F-0xFF : custom/extended glyphs - accented Hungarian/German letters, // Greek letters, and math symbols (see inline comments). // ============================================================================= byte _font[] = { 0x00, 0x00, 0x00, 0x00, 0x00, // 0x00 empty 0x3E, 0x5B, 0x4F, 0x5B, 0x3E, // 0x01 sad 0x3E,
