Crc8()

constexpr pw::checksum::Crc8::Crc8 ( uint8_t  polynomial, uint8_t  initial_value, bool  reflect_in, bool  reflect_out, uint8_t  xor_out  )

inlineconstexpr

Constructs a Crc8 calculator with the specified parameters.

Parameters

polynomial	The polynomial used for the CRC calculation.
initial_value	The initial value of the CRC register.
reflect_in	Whether the input bytes should be reflected before processing.
reflect_out	Whether the final CRC value should be reflected.
xor_out	The value to XOR with the final CRC result.
