Help with Calculation CRC16-CCITT

[crisares]

Hi all

Some would be so kind as to help me with the calculation CRC16-CCITT that I should do to a 4 byte hexadecimal string. I found some examples but they are text strings and not a hexadecimal value. I don't have much experience and I couldn't make the modifications to achieve it.

From already thank you very much

I'm not certain what is the problem, CRCs works on binary data and returns integer value,  in this case 16 bits. Then just convert it with inttohex().

Or attach minimalistic project code itself.
