Function Documentation

crc8()

uint8_t crc8	(	const uint8_t *	data,
		size_t	len,
		uint8_t	poly,
		uint8_t	seed
	)

Calculate CRC-8.

Parameters

[in]	data	Start of memory area to checksum
[in]	len	Number of bytes in buf to calculate checksum for
[in]	poly	The generator polynomial for the checksum
[in]	seed	The seed (starting value) for the checksum

Note

Reflected inputs or outputs and final XOR must be realized by the caller if needed.

Returns

Checksum of the specified memory area.
