Byte-wise XOR

[GS]

Help.

I am trying to do a BYTE-WISE XOR on a string to generate a checksum. In
short, how do I do this. I have looked at the XOR function on the functions
palate but it is a bitwise operation. FYI: this project involves interfacing
to a GPS receiver. I am reading/writing NMEA sentences. Any help or guidance
would be appreciated as I am new to using LabView.

define inputs as U8
unsigned 8
and wire them with the XOR gate

thats it

Did you solve the CRC calculation for the NMEA yet?

If you do coudl you post the answer? 

thanks
