Input data format

[ni5640]

Hi:

I am using ni5640r.

1. I want to transfer an array of data which is generated by labview from host to fpga by using Invoke method (write), do I need to set up I and Q before I transfer it and which format am I using U32, U16 or I16? 

2. In FPGA, when I read the data from host and send it to FPGA I/O node, do I need to convert it to 14 bit?

Thanks

Please refer to the Analog Input Output example which ships with the NI-5640R drivers.

C:\Program Files\National Instruments\LabVIEW 8.6\examples\instr\ni5640R\FPGA\PXIe-5641R\ni5640R Analog Input and Output\...

Hope this helps!
