CRC16C API Overview

CRC16C API assists you in generating CRC16C checksums.

CRC16C checksums can be generated in two modes: accumulative and non-accumulative.

The accumulative mode is applied when the data for which the checksum is calculated (data) represents one or more continuous memory block(s) or when the data is created at runtime in many steps (for instance, when reading a file).

Non-accumulative mode can be applied when the data represents one continuous memory block, a null-terminated string, or a file.

To generate the checksum in the accumulative mode, perform the following:

• Call the SL_FCRC16C_Init function to initialize the crc variable.

• Call the SL_FCRC16C_Update function for each continuous memory block of data to perform the calculations.

Note. You can use SL_FCRC16C_UpdateStr function (instead of SL_FCRC16C_Update function) if the data represents a null-terminated string.

• Call the SL_FCRC16C_Final function to obtain the checksum.

To generate the checksum in the non-accumulative mode, perform one of the following:

• Call the SL_FCRC16C_Calculate function if the data represents a continuous memory block.

• Call the SL_FCRC16C_CalculateStr function if the data represents a null-terminated string.

• Call the SL_FCRC16C_CalculateFile function if the data represents a file.
