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); | ||
