Detailed Description

Due to different implementations of data types in the world of C compilers, the following data types are used:

bool_t : Boolean value, True or False
uint8_t : 1 Byte value, value range 0 .. 2⁸ - 1 (0 .. 255)
int8_t : 1 Byte value, value range -2⁷ .. 2⁷ - 1 (-128 .. 127)
uint16_t : 2 Byte value, value range 0 .. 2¹⁶ - 1 (0 .. 65535)
int16_t : 2 Byte value, value range -2¹⁵ .. 2¹⁵ - 1
uint32_t : 4 Byte value, value range 0 .. 2³² - 1
int32_t : 4 Byte value, value range -2³¹ .. 2³¹ - 1
uint64_t : 8 Byte value, value range 0 .. 2⁶⁴ - 1
int64_t : 8 Byte value, value range -2⁶³ .. 2⁶³ - 1

The compiler type/version is evaluated via its internal predefined symbols. If your compiler is not (yet) supported, you will get the following error message upon compilation:

Data types are not defined! Please check compiler definition.

For GNU C compiler the predefined symbols can be obtained by the following command:

gcc -dM -E - < /dev/null

Macro Definition Documentation

◆ __STDC_VERSION__

#define __STDC_VERSION__ 0

◆ CPP_ALIGN

#define CPP_ALIGN ( x ) __attribute__ ((__aligned__(x)))

◆ CPP_BIG_ENDIAN

#define CPP_BIG_ENDIAN 0

◆ CPP_CONST

#define CPP_CONST const

The symbol CPP_CONST defines the expression for keeping data in the flash area.

◆ CPP_DATA_SIZE

#define CPP_DATA_SIZE 64

The symbol CPP_DATA_SIZE defines the largest supported data size (in bits) of the compiler. Typical values are 32 or 64. The data types uint64_t and int64_t are not supported if CPP_DATA_SIZE is 32.

◆ CPP_HAS_ATOMIC

#define CPP_HAS_ATOMIC 0

◆ CPP_INLINE

#define CPP_INLINE __inline

The symbol CPP_INLINE is used to declare a function as inline.

◆ CPP_NULL

#define CPP_NULL (void *) 0

◆ CPP_PACK

#define CPP_PACK __attribute__((packed))

The symbol CPP_PACK is used to pack data structures.

◆ CPP_PACK_PREFIX

#define CPP_PACK_PREFIX ( x ) x

◆ CPP_PARM_UNUSED

#define CPP_PARM_UNUSED ( x ) UNUSED_ ## x __attribute__((unused))

The macro CPP_PARM_UNUSED is used to specify function parameters which are currently not used.

◆ CPP_SECTION

#define CPP_SECTION

The macro CPP_SECTION is used to specify the memory section for the linker.

◆ CPP_WARNING

#define CPP_WARNING ( x )

◆ MC_FALSE

#define MC_FALSE 0

◆ MC_TRUE

#define MC_TRUE 1

Typedef Documentation

◆ bool_t

typedef _Bool bool_t

◆ Float_tu

typedef union Float_u Float_tu

◆ Status_tv

typedef int32_t Status_tv

Data type for status value.

The Status_tv typedef defines the data type for status values, typically used as return values. In order to keep the overhead small for different target platforms the data type can be adjusted.

Setting the symbol MC_COMPILER_EXT_H_ allows to include an external header file named "mc_compiler_ext.h".
