Here is my problem, i have several simmilar structue definitions (containers for messages)
struct FIRST{ unsigned char Word_Pos[8] unsigned char Data[8] unsigned char Msg_Len }; struct FIRST A
struct SECOND{ unsigned char Word_Pos[4] unsigned char Data[4] unsigned char Msg_Len }; struct SECOND B
struct THIRD{ unsigned char Word_Pos[10] unsigned char Data[10] unsigned char Msg_Len }; struct THIRD C
Is there a way to declare single pointer (lets say "P") such that i will be able to point to each of these structures so i can transparently use: P->Word_Pos [] P->Data [] P->MSG_Len in my ISR.
I realise i could just declare 3 structures of type THIRD and just use one pointer easily, but in my actual application there will be many of these simmilar but different structures and i am trying to save ram.
