/** \file server/drivers/serialVFD_displays.c
 * Setup routines for the inidividual displays supported by the \c serialVFD driver.
 * 
 * Here are the routines that set up the data as well as function pointers
 * for the individual displays supported by the \c serialVFD driver.
 *
 * If you want to add a new device to the driver add a new section
 * to the displaytype-switch-case in the init-function, add a new load_...
 * function below and fill it with the corrrect commands for the display.
 * (Try wich displaytype works best with your display, copy and modify
 * it's section that is the easiest way I guess.) 
 *
 * For each display the following setting have to be set in
 * serialVFD_private_data:
 * 
 * \li customchars       Number of possible custom characters
 * \li predefined_hbar   The display has predefined hbar-characters
 * \li hbar_cc_offset    Offset of the predefined hbar-characters
 * \li predefined_vbar   The display has predefined vbar-characters
 * \li vbar_cc_offset    Offset of the predefined vbar-characters
 * \li hw_cmd            Table with hardware commands (see below)
 * \li charmap           Table mapping characters 127...255 to other chars
 * \li usr_chr_dot_assignment  Mapping of icon bits (see below)
 * \li usr_chr_mapping   Map indicating which chars may be overwritten in RAM
 * \li usr_chr_load_mapping  Location byte (see below)
 *
 * \b hw_cmd:
 * The hw_cmd is a two-dimensional array used as a table to store hardware-
 * dependant command. 10 commands are supported. For each command a byte
 * array is set with the 1st byte defining the command length (which may be
 * zero) and up to 9 bytes of command. The following commands exist:
 * 
 * \li Set brightness level 0
 * \li Set brightness level 1
 * \li Set brightness level 2
 * \li Set brightness level 3
 * \li Move cursor to Pos1
 * \li Move cursor to position X
 * \li Reset
 * \li Initialize
 * \li Set user character
 * \li Horizontal tab
 * \li Move cursor to next line
 *
 *\verbatim
 * hw_cmd[Command][data] = {{commandlength , command 1},
 *                          .....
 *                          {commandlength , command N}}
 *\endverbatim
 *
 * \b usr_chr_dot_assignment:
 * usr_chr_dot_assignment is an array specifying how our 5x7 matrix of custom
 * character bits are mapped into user defined characters (UDC). The very
 * first byte of usr_chr_dot_assignment gives the number of bytes this VFD
 * uses for one UDC. The remaining numbers give which byte/bit if a UDC hold
 * which bit of the 5x7 matrix.
 *
 * Note: LSB of an icon line is the leftmost entry in the array!
 *
 * \b usr_chr_load_mapping:
 * Usually any character may be overwritten in RAM. Some VFD however use
 * an index number for user defined characters. The usr_chr_load_mapping
 * array specifies which byte of usr_chr_mapping is assigned which index.
 *
 * For displays not using index numbers usr_chr_load_mapping is a copy of
 * usr_chr_mapping.
