Unflattening FXP array yields incorrect results

[Kyle_UCT]

Hello,

I am trying to send some data from my RIO to the PC via Ethernet.

To do this, I am flattening the data (an array of FXP numbers) to String on the RIO.

On the PC, I am unflattening the data, but obtaining different results.

Any idea what's wrong?

Thanks in advance!

Hi Kyle, Thank you for your post and welcome to the NI forums. The first suggestion I would make is, regarding the FXP data you are passing around, have you made sure that the word and integer lengths are the same on both sides? If these are different you would expect the data to be different. Thanks,

Eden is right. You're flattening FXP<+,16,3> data on the RIO, but you unflatten the data to FXP<+-,64,32> on the host. This can not work.

Thank you very much, Eden_S and dan_u. That fixed the problem.
