Deepika	4d7fdfc2a9	Use MbedCRC for LittleFS (0xEDB88320) ... CRC used in LittleFS is Reversed ANSI, hence new polynomial added. Reversed polynomials perform shift in reverse direction of standard polynomial, and we do not have option to notify reverse shift to hardware. Hence this option is available in software only.	2018-09-02 15:25:40 -05:00
deepikabhavnani	531a83ebd2	Add optimized implementation of 32-bit ANSI CRC	2018-08-09 17:27:07 -05:00
deepikabhavnani	b60eb1d001	Updated table to be const and small fixes	2018-02-27 09:35:55 -06:00
deepikabhavnani	8e537115c5	Removed init/deinit and added cpp file for tables	2018-02-02 09:43:06 -06:00
deepikabhavnani	afe8834bb8	CRC class implementation ... CRC class `MbedCRC.h` is templated class created to support hardware/software CRCs. Default CRC will be hardware CRC when support for HAL is available. Polynomial tables are available for 8/16 bit CCITT, 7/16 bit for SD card and 32-bit ANSI. Polynomial table implementation will be used if Hardware CRC is not available. In case device does not have hardware CRC and polynomial table is not supported, CRC is still available and is computed runtime bit by bit for all data input.	2018-01-24 13:26:41 -06:00
