 Overview: This VI takes in a string variable and calculates the 16-bit CRC value based on the CRC16-CCITT standard (polynomial 0x1021) with seed value of 0xFFFF ONLY.

Description:

This VI takes in a string variable and calculates the 16-bit CRC value based on the CRC16-CCITT standard (polynomial 0x1021) with seed value of 0xFFFF ONLY. This VI code is based on an extremely efficient implementation originally intended for microcontrollers and is adapted for LabVIEW.

Requirements: LabVIEW 2012 (or compatible).

Steps to Implement or Execute Code:

1. Input a string.
2. Run this VI.
