FIFO write / FIFO read data type difference

[smahlen]

Hello!

My problem is my FIFO on the FPGA side is a fixed point data type:

Where on the host when I read the FIFO it is a completely different data type (U64):

This does present a problem since I have negative data. I've tried delating and replacing and the FIFO properties have it as a fixed point data type that is signed. 

How do I fix this?

How is your FPGA reference opened from the host side ?

If you are referencing a Bitfile, the data types won't update on the host side after you make a change to your FPGA VI.

You either need to recompile your lvbitx or change the reference mode to either VI or Build Specification.

That helped me a lot thank you!
