-/* This file provides translation primitives and tables for the conversion
- * of (ASCII) characters to a 7-segments notation.
- *
- * The 7 segment's wikipedia notation below is used as standard.
- * See: http://en.wikipedia.org/wiki/Seven_segment_display
- *
- * Notation: +-a-+
- * f b
- * +-g-+
- * e c
- * +-d-+
- *
- * Usage:
- *
- * Register a map variable, and fill it with a character set:
- * static SEG7_DEFAULT_MAP(map_seg7);
- *
- *
- * Then use for conversion:
- * seg7 = map_to_seg7(&map_seg7, some_char);
- * ...
- *
- * In device drivers it is recommended, if required, to make the char map
- * accessible via the sysfs interface using the following scheme:
- *
- * static ssize_t show_map(struct device *dev, char *buf) {
- * memcpy(buf, &map_seg7, sizeof(map_seg7));
- * return sizeof(map_seg7);
- * }
- * static ssize_t store_map(struct device *dev, const char *buf, size_t cnt) {
- * if(cnt != sizeof(map_seg7))
- * return -EINVAL;
- * memcpy(&map_seg7, buf, cnt);
- * return cnt;
- * }
- * static DEVICE_ATTR(map_seg7, PERMS_RW, show_map, store_map);
- *
- * History:
- * 2005-05-31 RFC linux-kernel@vger.kernel.org
