The "library": two files crc.c and crc.h in the periph directory.
The main.c contains buffer with test data and provides CRC calculations for the different standards (CRC size and initial values). The results will be printed in two values, the first - is the calculated CRC for the data buffer using the CRC unit, the second - test value calculated with CRC different utilities. Both values must be identical :)
Also note: in word and half-word calculations the input bit reversing is still configured as per-byte, this is done due to features of function CRC_CalcBuffer().
An output of demo code in main.c must be something like this:
