  Name         :  LcdChr
  Argument(s)  :  Ctrl = X*X_MUL+y*Y_MUL+ BIG1 + BIG2 + OutLen
                  Inverse == 1 - inverse output
                  Str - out string
 Description  :  Displays a character at current cursor location and increment cursor location.
              Len from 0 to 84
              y from 0 to 5
              x from 0 to 13
              BIG_UP -  upper part of 16 point string
              BIG_DOWN -lower part of 16 point string 
              BIG_UP   | Y2 | Y1 | Y0 | X3 | X2 | X1 | X0
              BIG_DOWN | L6 | L5 | L4 | L3 | L2 | L1 | L0
              It is parts of Ctrl. Ctrl = X_MUL*X+Y_MUL*Y+LENGTH+(BIG_UP||BIG_DOWN||0)
              Length should be >= strlen(Str). 
              Example:LcdChr(5*X_MUL+3*Y_MUL+8, 1, "123") - will out string 123 in position 6 row 4 8 points font.
              The 5 symbols afrer 123 will be cleaned ( 8 - strlen("123"))

  Return value :  None.
