Easiest way to convert a CAN frame that is in the form of an 8-byte array to a single 64-bit integer?

[Incrementum]

I am writing a program that will test a manufactured unit. I figure the easiest way to run through really long automated test procedures is to compare bit patterns of entire frames. I have been trying to accomplish turning a read frame into a 64-bit integer for the last few hours and I just can't seem to get it to work. Does anyone have any ideas?

thanks,

Well, I came up with something that works but I feel like an easier way exists that I don't know about. I basically converted the 8 bytes into 64-bit integers, shifted them, and then added them together.

Type cast?

[Incrementum]

Yes, this was one of the first things that I tried. The problem is that it outputs a string. You can choose it to display as HEX, but when you try to compare a static value and the output it doesn't recognize that they are the same because of the different data types.

OK, I'm a little slow. I apparently didn't know how to manipulate the Type Cast correctly.

Thank you for your solution.

The Type Cast is the correct way to do this.  However I've seen performance is slightly better with joining of values.  I didn't test the performance with shifting.  When I do conversions like this I call an inlined subVI.

This is what is used in my Frame Signal conversion library.
