Detailed Description

Interface: console input / output.

Author:
Markus L. Noga <markus@noga.de>
Warning:
If CONF_LCD_REFRESH is set in config.h, the kernel will refresh the display automatically every 100ms. Otherwise, display updates are realized exclusively by lcd_refresh().
Display positions
Digit display positions are denumerated from right to left, starting with 0 for the digit to the right of the running man.
LCD Postions: 5 4 3 2 1 {man} 0
NOTE: Position 5 is only partially present on the LCD display.
Native segment masks
In these bitmasks, bit 0 toggles the middle segment. Bit 1 toggles the top right segment, and the remaining segments are denumerated counterclockwise. The dot isn't encoded because it is desirable
