Function Documentation

uint16_t usCrcCcitt	(	uint16_t	usCrc,
		const void *	pvBuf,
		size_t	uLen
	)

#include <crc.h>

This function implements the CRC-CCITT calculation on a buffer.

Parameters

crc	Current CRC-CCITT value.
buf	The buffer to perform CRC calculation on.
len	The length of the Buffer.

Returns

The updated CRC-CCITT value.
