Function Documentation

compute16CCITT()

uint16_t compute16CCITT	(	const uint8_t *	buf,
		size_t	buf_length
	)

This function computes the CRC-8-CCITT (Cyclic Redundancy Check) of a buffer "buf" of "buf_length" bytes.

Parameters

[in]	buf	The buffer at hand
[in]	buf_length	Number of bytes in "buf"

Returns

The calculated CRC

Definition at line 40 of file crc.cpp.

isValid()

bool isValid

(

const uint8_t *

block

)

Validates whether the calculated CRC of the SBF block at hand matches the CRC field of the streamed SBF block.

Parameters

block

The SBF block that we are interested in

Returns

True if the CRC check of the SBFBlock has passed, false otherwise
