CRC-16 /CCITT false implementation

[nagesh]

Tried all the available VI's.

Not able to find the required checksum.

For example :

for data in hexa 252000 i need checksum A74C

Use the CRC Calculator:
https://crccalc.com/

=> CRC-16/CCITT-FALSE

Sorry, did not read your question precisely... ;-(

You can use this library:
CRC16-CCITT-0xFFFF

CRC_VIs85.zip

I have tried this..

But it is not working..

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.....

This seems to work...

CRC16-CCITT-FALSE.vi

thank you @crossrulz

This is working fine.

I had to modified it and work with my model.
