Hi everyone, I am using labview 2017 and getting measurements from my serial port. I don't have any problems receiving the data but still, I would like to check it out using the CRC-16. It is a CRC-16 based on polynomilal 0x8005 with an initial value at 0x0000. Here is an example of the fata I get : 5B01D0010088065D 5B is the start of packet 5D is the end if packet 8806 is the CRC-16 in this particular example and applies to evrything before (meaning : 5B01D00100) When using this online CRC calculator I get the good CRC (need to swap the values) looking at line "CRC-16/BUYPASS". So i guess that is the offical name of the CRC-16 I am looking for. I have tried using the solution in this post, but it doesn't workout for me :https://forums.ni.com/t5/LabVIEW/CRC-16-with-0x8005-polynomial/td-p/3271384/page/2 And it corresponds to the "CRC-16/ARC" of the online calculator. Would anyone know where I could find the CRC-16/BUYPASS VI ? Thanks. User

Solved!

Hi Jamiva,

Good Afternoon,

This is my HEX Value (01 01 1F) for CRC value calculation.

The CRC value come in online calculator (5860)

But, in LabVIEW code i get the CRC value is (5586)

Could you please support me to solve the issue?
