Hallo,
Ich habe einige Probleme mit dem NOR-FLASH und einenem TFT am FSMC BUS,
beides zusammen geht nicht.
Initialiesiere ich nur das TFT dann gehts wenn ich das NOR FLASH mit 
dazu initialiesiere geht das TFT nicht mehr.
Vielleicht kann mir wer helfen.

Also, du erwartest nicht wirklich, daß sich andere Leser durch deinen 
Wust und auch noch durch die unsäglichen ST-Libs durchackern, oder?

Mein Rat: schmeiß die ST-Libs weit, weit weg und baue dir deinen Code 
selber.

Ich hänge dir mal ein Beispiel dran, damit du sehen kannst, wie ich 
sowas angehe. Auf dem Board ist ein 1 MB SRAM und ein CPLD, was ein TFT 
bedient, 480x272, 16 Bit Farbe (565).

Wenn du Bedarf nach weiteren Quellteilen hast, dann schreib es. 
Allerdings ist es für dich wahrscheinlich einfacher, die eine oder 
andere Sache aus der Lernbetty (hier in der Codesammlung) zu entnehmen, 
denn ein ziemlicher Teil ist zwischen beiden Projekten gleich.
