Array

[SJ BSB]

Hello,

I new to LabVIEW. I need an Array to be passed from Host PC to RT and then to FPGA VI. I started implementing from FPGA VI. I am getting error "Arrays must be fixed size in current target"

For the FPGA, you need to set the size of the Array.

Right click...and select: Set Dimension Size

I tried doing it but still i have the error.

Are you using a fixed size array for manipulation? Posting a snapshot of your block diagram where the array manipulation takes place would help us.

For the FPGA, make sure you have checked every array? (including SubVIs and array constants).

All FPGA Arrays have to be a fixed size

Also, are you using the Build Array function anywhere in the FPGA?

If so, then there may be an option somewhere that you need to set (I'm trying to find it now)

Select: File > VI Properties > Execution

Then check: Auto preallocate Arrays and Strings

See if that helps.

I have changed from array to cluster. Initially I took the parameters by indexing array. Now it is fine and working. I have attached the new VI
