CRC-16 with 0x8005 polynomial

[swbpnole]

I am not getting the expect result. I modified the VI to look like this:

Could you post a picture of your modified version?

The 0x1FF3 should be 0x4042...

Here, use this.

Could explain this one? Why the changes?

This VI is based on a setup I have had for a very long time.  Like I said before, there are many different ways to do a CRC.  In this case, we needed to shift the CRC to the left while the Data is shifted to the left.

Are you using a PC? This is too wierd I am not getting this...

Try right-clicking on the Boolean Array To Number and select properties.  There is a tab in there to allow you to change the output data type.  Change that to a U16.  I'm not seeing anything else obviously wrong.

Between you and the NI AE, I realized it was my polynomial and initial value representations, both were I32 and should have been U16. Thanks...
