Calculate CRC according to CCITT standard.
This function takes length bytes from buf and calculates the CRC for this data. The result is returned.
- Note:
- This implementation calculates the CRC with LSB first, i.e. all bytes are "read" from right to left.
- Parameters:
-
[in] preloadValue : Initial value of CRC calculation. [in] buf : buffer to calculate the CRC for. [in] length : size of the buffer.
- Returns:
- 16 bit long crc value.
