Macro Definition Documentation

RAND_LOCAL_MAX

#define RAND_LOCAL_MAX   2147483647L

Redefinition of rand() and srand() standard C functions. These functions are redefined in order to get the same behavior across different compiler toolchains implementations.

Function Documentation

rand1()

int32_t rand1

(

void

)

srand1()

void srand1

(

uint32_t

seed

)

Initializes the pseudo random generator initial value.

Parameters

seed	Pseudo random generator initial value

randr()

int32_t randr	(	int32_t	min,
		int32_t	max
	)

Computes a random number between min and max.

Parameters

min	range minimum value
max	range maximum value

Return values

random

random value in range min..max

memcpy1()

void memcpy1	(	uint8_t *	dst,
		const uint8_t *	src,
		uint16_t	size
	)

Copies size elements of src array to dst array.

Remarks

STM32 Standard memcpy function only works on pointers that are aligned

Parameters

dst	Destination array
src	Source array
size	Number of bytes to be copied

memcpyr()

void memcpyr	(	uint8_t *	dst,
		const uint8_t *	src,
		uint16_t	size
	)

Copies size elements of src array to dst array reversing the byte order.

Parameters

dst	Destination array
src	Source array
size	Number of bytes to be copied

memset1()

void memset1	(	uint8_t *	dst,
		uint8_t	value,
		uint16_t	size
	)

Set size elements of dst array with value.

Remarks

STM32 Standard memset function only works on pointers that are aligned

Parameters

dst	Destination array
value	Default value
size	Number of bytes to be copied

Nibble2HexChar()

int8_t Nibble2HexChar

(

uint8_t

a

)

Converts a nibble to an hexadecimal character.

Parameters

a	Nibble to be converted

Return values

hexChar

Converted hexadecimal character
