int  p  int   0x1234   10    0x1234 is the memory address and value 10 is assigned in that address   unsigned int  ptr  unsigned int   0x903jf   20   0x903j is memory address and value 20 is assigned    Basically in Embedded platform we are using directly addresses instead of names

Like this   void   p    void   0x28ff44    Or if you want it as a char     char   p    char   0x28ff44       etc   If you re pointing to something you really  really aren t meant to change  add a const   const void   p    const void   0x28ff44  const char   p    const char   0x28ff44       since I figure this must be some kind of  well-known address  and those are typically  though by no means always  read-only

Your code would be like this   int  p    int   0x28ff44    int needs to be the type of the object that you are referencing or it can be void   But be careful so that you don t try to access something that doesn t belong to your program

let s say you want a pointer to point at the address 0x28ff4402  the usual way is uint32 t  ptr  ptr    uint32 t   0x28ff4402   type-casting the address value to uint32 t pointer  ptr     1 lt  lt 13     1 lt  lt 10     access the address how ever you want  So the short way is to use a MACRO   define ptr   uint32 t     0x28ff4402
