Using the CRC Module on Hercules™-Based Microcontrollers

and the accompanying linked software examples (available at http://www.ti.com/lit/zip/spna235).

The CRC function ‘generate_crc_64_for_tms570_on_board_crc_calculation’ is implemented in Python based on the example code from ‘CRC64_calc.c’ (which is part of http://www.ti.com/lit/zip/spna235).
