crc crcFast	(	unsigned char const	message[],
		int	nBytes
	)

void crcInit

(

void

)

crc crcSlow	(	unsigned char const	message[],
		int	nBytes
	)

unsigned char generate_crc7	(	unsigned char *	buf,
		unsigned char	bytes
	)

Generate CRC7.

This function generates a 7 bit CRC using the X^7 + X^3 + 1 polynomial

Parameters:

Parameters:

	buf	Pointer to the first data byte to be calculated
	bytes	Total number of bytes to be included in crc calculation

Returns:

7 bit CRC value
