Микроконтроллеры PIC

У меня 2 работает. /* Multi-byte word access macros */ #if _MCU_ENDIAN == 1 /* Use word access */ #define LD_WORD(ptr) (WORD)(*(WORD*)(BYTE*)(ptr)) #define LD_DWORD(ptr) (DWORD)(*(DWORD*)(BYTE*)(ptr)) #define ST_WORD(ptr,val) *(WORD*)(BYTE*)(ptr)=(WORD)(val) #define ST_DWORD(ptr,val) *(DWORD*)(BYTE*)(ptr)=(DWORD)(val) #elif _MCU_ENDIAN == 2 /* Use byte-by-byte access */ #define LD_WORD(ptr) (WORD)(((WORD)*(volatile BYTE*)((ptr)+1)<<8)|(WORD)*(volatile BYTE*)(ptr)) #define LD_DWORD(ptr) (DWORD)(((DWORD)*(volatile BYTE*)((ptr)+3)<<24)|((DWORD)*(volatile BYTE*)((ptr)+2)<<16)|((WORD)*(volatile BYTE*)((ptr)+1)<<8)|*(volatile BYTE*)(ptr)) #define ST_WORD(ptr,val) *(volatile BYTE*)(ptr)=(BYTE)(val); *(volatile BYTE*)((ptr)+1)=(BYTE)((WORD)(val)>>8) #define ST_DWORD(ptr,val) *(volatile BYTE*)(ptr)=(BYTE)(val); *(volatile BYTE*)((ptr)+1)=(BYTE)((WORD)(val)>>8); *(volatile BYTE*)((ptr)+2)=(BYTE)((DWORD)(val)>>16); *(volatile BYTE*)((ptr)+3)=(BYTE)((DWORD)(val)>>24) #else #error Do not forget to set _MCU_ENDIAN properly! #endif
