24/* This file provides translation primitives and tables for the conversion
25 * of (ASCII) characters to a 7-segments notation.
26 *
27 * The 7 segment's wikipedia notation below is used as standard.
28 * See: http://en.wikipedia.org/wiki/Seven_segment_display
29 *
30 * Notation: +-a-+
31 * f b
32 * +-g-+
33 * e c
34 * +-d-+
35 *
36 * Usage:
37 *
38 * Register a map variable, and fill it with a character set:
39 * static SEG7_DEFAULT_MAP(map_seg7);
40 *
41 *
42 * Then use for conversion:
43 * seg7 = map_to_seg7(&map_seg7, some_char);
44 * ...
45 *
46 * In device drivers it is recommended, if required, to make the char map
47 * accessible via the sysfs interface using the following scheme:
48 *
49 * static ssize_t show_map(struct device *dev, char *buf) {
50 * memcpy(buf, &map_seg7, sizeof(map_seg7));
51 * return sizeof(map_seg7);
52 * }
53 * static ssize_t store_map(struct device *dev, const char *buf, size_t cnt) {
54 * if(cnt != sizeof(map_seg7))
55 * return -EINVAL;
56 * memcpy(&map_seg7, buf, cnt);
57 * return cnt;
58 * }
59 * static DEVICE_ATTR(map_seg7, PERMS_RW, show_map, store_map);
60 *
61 * History:
62 * 2005-05-31 RFC linux-kernel@vger.kernel.org
