Function Documentation

crc8_0x2F()

WS_DLL_PUBLIC uint8_t crc8_0x2F	(	const uint8_t *	buf,
		uint32_t	len,
		uint8_t	seed
	)

Calculates a CRC8 checksum for the given buffer with the polynom 0x2F using the precompiled CRC table

Parameters

buf	a pointer to a buffer of the given length
len	the length of the given buffer
seed	The seed to use.

Returns

the CRC8 checksum for the buffer

crc8_0x37()

WS_DLL_PUBLIC uint8_t crc8_0x37	(	const uint8_t *	buf,
		uint32_t	len,
		uint8_t	seed
	)

Calculates a CRC8 checksum for the given buffer with the polynom 0x37 using the precompiled CRC table

Parameters

buf	a pointer to a buffer of the given length
len	the length of the given buffer
seed	The seed to use.

Returns

the CRC8 checksum for the buffer

crc8_0x3B()

WS_DLL_PUBLIC uint8_t crc8_0x3B	(	const uint8_t *	buf,
		uint32_t	len,
		uint8_t	seed
	)

Calculates a CRC8 checksum for the given buffer with the polynom 0x3B using the precompiled CRC table

Parameters

buf	a pointer to a buffer of the given length
len	the length of the given buffer
seed	The seed to use.

Returns

the CRC8 checksum for the buffer
