LCD Menü CvAVR in WiAVR

Hallo,

ich habe einen Teil, eines LCD Menüs, welches in CVAVR programmiert 
wurde.
Da ich aber mit WinAVR meine Programme versuche zu schreiben,
brauche ich Hilfe, bei der Umsetzung von CVAVR in WinAVR.

Hier die Teile, des LCD Menüs, ich hoffe, es steigt jemand durch.
Es sind wirklichnur Teile des Programms, es fehlen einige Funktionen, 
die aber nicht für das Menü gebraucht werden, denke ich.

flash char menu[72][18] = {"A","B","C","D","E","F","G","H",
                           "1-a","2-a","3-a","4-a","5-a","6-a","7-a","8a",
                           "1-b","2-b","3-b","4-b","5-b","6-b","7-b","8b",
                           "1-b","2-b","3-c","4-c","5-c","6-c","7-b","8b",
                           "1-d","2-d","3-d","4-d","5-d","6-d","7-d","8-d",
                           "1-e","2-e","3-e","4-e","5-e","6-e","7-e","8-e",
                           "1-f","2-f","3-f","4-f","5-f","6-f","7-f","8-f",
                           "1-g","2-g","3-g","4-g","5-g","6-g","7-g","8-g",
                           "1-h","2-h","3-h","4-h","5-h","6-h","7-h","8-h"
                            };
