Cloedu72 Posted January 27, 2021 Report Share Posted January 27, 2021 (edited) Use the CRC Calculator: https://crccalc.com/ => CRC-16/CCITT-FALSE Sorry, did not read your question precisely... ;-( Edited January 27, 2021 by Cloedu72 Quote Link to comment
Cloedu72 Posted January 27, 2021 Report Share Posted January 27, 2021 You can use this library: CRC16-CCITT-0xFFFF CRC_VIs85.zip Quote Link to comment

nagesh Posted January 27, 2021 Author Report Share Posted January 27, 2021 (edited) http://www.sunshine2k.de/coding/javascript/crc/crc_js.html Add reference of type i need. In above link there are two possibilities: 1) Custom with 0x1021 polynomial , 0xFFFF as the initial Value and 0x0 as the final Xor value. 2) Predefined type CRC16_CCITT_FALSE. With other settings: a) CRC width (Bit Length) is CRC-16 b) CRC Input Data is bytes. I am stuck at this point....... Need Help..... Edited January 27, 2021 by nagesh Quote Link to comment
