uint8_t mirror_byte (uint8_t value)

mirror_byte This function is used to mirror a Byte (LSB -> MSB and so on) (This is used if the Display is physically used in 12:00 mode -
otherwise the Characters will be broken)

Detailed Description

This is the header file for using the Graphic-LCD
.

It handles all LCD specific functions.
It could be used with C167 AND AVR90USB
