Web* generate a ccitt 16 bit cyclic redundancy check (crc) * The code in this module generates the crc for a block of data. * * Version: 1.0.2 * Author: Joao Alves * Required files: crc16.cpp, crc16.h * * History: * 1.0.2 - 2024-03-14 - Initial Version * * This library is free software; you can redistribute it and/or modify Calling the function "to update the current CRC" doesn't make any sense, because the function doesn't retain the previous FCS but starts at blank data, all ones = 0xFFFF, as required by CRC16-CCITT. If you wish to continuously update the FCS, you would have to save it then pass it to the function with each call.
