Adresse in Enumeration hinterlegen

[karl (Gast)]

Hallo, ich drehe mich gerade im Kreis, denn ich versuche eine Adresse in 
einer Enumeration zu speichern. Wie mache ich denn das. Der C-Compiler 
meckert immer bei "DMA6_Config_PAD_Address = (&U2RXREG)".

Danke schonmal.

Steht doch klar und deutlich da: Ein Enum möchte Konstanten!

Jo stimmt, mensch. Ich machs dementsprechend mit #define. Irgendwie nich 
mehr so ganz fit.
Nacht :D
