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]bufThe buffer at hand
[in]buf_lengthNumber 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
blockThe SBF block that we are interested in
Returns
True if the CRC check of the SBFBlock has passed, false otherwise
