27 * The 7 segment's wikipedia notation below is used as standard.

29 *
30 * Notation: +-a-+
31 * f b
32 * +-g-+

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) {
