UCRC16_CCITT_POLY_BE¶

Various generator polynomials.

(0x1021)

CRC16-CCITT polynomial (big-endian)

UCRC16_CCITT_POLY_LE¶

CRC16-CCITT polynomial (little-endian)

(0x8408)

uint16_t ucrc16_calc_be(const uint8_t * buf, msp430_types.h::size_t len, uint16_t poly, uint16_t seed)¶

Calculate CRC16 (big-endian version)

Parameters

buf:	Start of memory are to checksum
len:	Number of bytes in `buf` to calculate checksum for
poly:	The generator polynomial for the checksum
seed:	The seed (starting value) for the checksum

Note

The return value is not the complement of the sum but the sum itself

Return values

Parameters

buf:	Start of memory are to checksum
len:	Number of bytes in `buf` to calculate checksum for
poly:	The generator polynomial for the checksum
seed:	The seed (starting value) for the checksum
