LabVIEW FPGA Read/Write Module - Changing data types

Solved!
Go to solution

Hi All,

 

I'm using the FPGA read/write modules to communicate between my host computer and an FPGA, but I'm having trouble changing the data type of the data I'm trying to send. It seems like such a simple thing, but I can't figure it out. I've looked through the settings when I right click on it and I've restarted the computer. When I left click on the tabs, I can choose from the data types that were used previously in the example, but string isn't an option.

First of all, the I/O shows Unselected. You need to select which front panel items to write to.

Secondly, String data type is not supported in FPGA. By definition,strings are variable in size. An FPGA is pure hardware and therefore can't handle variable sized data types.

You can use Enum which couples an integer data with a string display.
