Detailed Description

This module implements the CRC-16 calculation in the blocks.

Function Documentation

uint16_t crc16_compute	(	const uint8_t *	p_data,
		uint32_t	size,
		const uint16_t *	p_crc
	)

Function for calculating CRC-16 in blocks.

Feed each consecutive data block into this function, along with the current value of p_crc as returned by the previous call of this function. The first call of this function should pass NULL as the initial value of the crc in p_crc.

Parameters

[in]	p_data	The input data block for computation.
[in]	size	The size of the input data block in bytes.
[in]	p_crc	The previous calculated CRC-16 value or NULL if first call.

Returns

The updated CRC-16 value, based on the input supplied.
