Detailed Description

Macro Definition Documentation

◆ ZB_RAND_MAX

#define ZB_RAND_MAX ((zb_uint32_t)~0U)

Maximal possible value for randomly generated (32-bit) value

◆ ZB_RANDOM_U16

#define ZB_RANDOM_U16 ( ) zb_random_u16()

Equivalent of zb_random_u16(). The macro is left for compatibility reasons.

◆ ZB_RANDOM_U8

#define ZB_RANDOM_U8 ( ) zb_random_u8()

Equivalent of zb_random_u8(). The macro is left for compatibility reasons.

◆ ZB_RANDOM_VALUE

#define ZB_RANDOM_VALUE ( max_value ) zb_random_val(max_value)

Equivalent of zb_random_val(). The macro is left for compatibility reasons.

Function Documentation

◆ zb_bzero_volatile()

void zb_bzero_volatile	(	volatile void *	s,
		zb_uint_t	size
	)

Analogue of bzero() for volatile data.

A custom version should be implemented because there is no standard library function for that purpose. Also, this function is not platform-dependent in contrast to ZB_BZERO() macro and therefore can't be overridden by specific ZBOSS platform.

The function sets individually every byte of provided memory region to zero.

◆ zb_generate_prbs9()

void zb_generate_prbs9	(	zb_uint8_t *	dest,
		zb_uint16_t	cnt,
		zb_uint16_t	seed
	)

Fill in memory with PRBS9 pattern using linear-feedback shift registers.

Parameters

dest	- Pointer to the block of memory to fill.
cnt	- Number of bytes to be set.
seed	- Random seed

◆ zb_random()

zb_uint32_t zb_random ( void )

Generate random 32-bit value using zb_random_val() with ZB_UINT32_MAX

Returns: random value between 0 to 2^32-1

◆ zb_random_u16()

zb_uint16_t zb_random_u16 ( void )

Generate random 16-bit value using zb_random_val() with ZB_UINT16_MAX

Returns: random value between 0 to 0xffff

◆ zb_random_u8()

zb_uint8_t zb_random_u8 ( void )

Generate random 8-bit value using zb_random_val() with ZB_UINT8_MAX

Returns: random value between 0 to 0xff

◆ zb_random_val()

zb_uint32_t zb_random_val ( zb_uint32_t max_value )

Generate random value between 0 to max_value, inclusively.

Internal software algorithm using LFSRs can be overridden by define ZB_RANDOM_HARDWARE

Returns: random value between 0 and 'max_value' (32 bits).
